What do we have in Office 365?

6. Office 365 Groups – General
I found this interesting illustration talking about process leading to SUCCESS!
Office 365 groups are just more than a feature and will help team organizing, structure and have
efficiency set as a key objective in daily work life.
There is a reason, why Office 365 is also called a PRODUCTIVITY SUITE. Why is this?
A look into our daily work (and you will find yourself in here too)
In our daily work we receive emails, most likely a lot. In my current job as Business Development
Manager, I have received in a single year more than 25.000 mails. Which is incredible high. If I
assume I spend approx. 30 sec on each mail, including say 10% I need to react on. Let’s see how
much time I spend in total on Email.
(25.000 * 30 sec)/3600 = 208,33 hrs -> 26 days
That’s a lot of time! As is said, I need to react on 10% only, I waisted 24 days. With costs my
company more than an entire monthly salary.
I was now looking into a way how to manage this Email flood proper. First step was (still bevor O365
Groups) creating a lot of Outlook Server rules. Especially those where I’m cc’ed on and moved them
into a sub-folder, creating further more rules, simply deleting emails without reading them. This btw,
is a dangerous task, since you could loose important mails.
Well, the cc’ed rule got already 25% of all my mail consolidated in folder, which enabled me run
through those mail must fast, once I have a couple of minutes time.

7. Now, I was looking into the issue
I consulted during my past jobs. This enabled me not only for technical designs based on customer
requirements, no it enabled me for transforming with Office 365 into business process consulting.
And this is what was needed.
Here some findings what was happened:
- We have traditional distribution groups
- We receive a lot information from vendors
- We have tools and applications sending emails
- We are used to sending documents across multiple DLs
- We used shared calendars (as a team calendar)
I could continue the list with findings. At this moment, I was digging into the root cause findings, I felt
instantly catapulted back to those good old days with Exchange 5.5 😊
Let’s have a look into two issues, which you instantly can address with Office 365 Groups.
Starting with traditional Distribution Lists:
Send mail to a DL, causes everyone receiving information which might not be relevant to them.
Causing instant disruption of their work.
Next this DL’s cause, where, vendor information where sometime send multiple time across different
DL’s, meaning at the end, the same email was received up to 6-times.
Distributing files via email:
Once we started working on procures or even quotes, those were sent to DLs or multiple person
involved. Until a document was final, not seldom I had more than 20 copies in my mailbox. Good
was, if none of our workmate changed the mail subject, outlook is able grouping this conversation in
useful view. But versioning was not there!
In total, my mailbox growth was 9GB in one year. Can you imagine. This can’t be the efficient way of
work.
After the first Office 365 Group was established, we experienced a significant reduction of the email
blasts. We shared documents via OneDrive (SharePoint), had a structured calendar, organized task in
Planner, started working with consolidated OneNotes. Best ever, the conversation in the Team Email
folder help following up with work, and more the amount of emails was reduced further.
My personal email flood reduced down to less than 18 mails in my inbox and around 6 in cc’ed
subfolder. This is taking my incoming mails down by approx. 6.000 plus around 5.000 in the team
Office 365 Group.
And it’s not the end yet. Now the next level is in progress, once Teams is activated!!
Today we increased the work efficiency per person by:
48% based on Email measuring!

8. Comparing Group features in Office 365
Office 365 Admin Portal has the following selection of Group types. Form here we go further into the
usability and example scenarios.
Type of Group Description Creating Features
1
Office 365

Communicate, collaborate,
scheduling events and planning

Users can create
Groups by
themselves or if

2 Distribution list Simple email distribution Admins only - - Nothing - -
3 Shared

Share mailbox, where uses reply
with from “on-behalf”
Admin sonly Outlook based
second mailbox
4
Security group
Only for managing security and
rights
Admin only Only security and
right management
5 Mail-enabled
security group
Combination of DL and SG Admin only Only security and
right management
Before I describe the Office 365 Group, I’m looking into the other groups first.
Distribution List:
This is a traditional group used in the past for team collaboration. It simply replicates, send an email
to multiple members at one shot. This duplicate an email several times and could start flooding
mailboxes. Remember the incident, where an email was send to “all”, this crashed the email servers
at the Germany government a couple of years ago.
In today’s environment, the best way using DLs is for example distributing scheduled events, like a
team meeting. Another scenario would be very important mails the team or an entire organization
needs to receive, even here could be s segregation/ classification of the those mails into mails with
must be read or the team/ organization SharePoint site. News or information could be spread
according their importance very well with this approach.
Security Group:
This is a straight forward usability, everything requires permission, like SharePoint resources, or
MDM (Mobile Device Management). This approach is best if security segregation is key.
Mail-enabled Security Group:
This is the efficient combination of both topic above. Where you could consolidate security and
distribution of important information at the same time and will reduce admirative efforts. But it
should be used wisely. Best Practice consulting advice would use DL and SG but try not combining
them.
Share Mailbox:
Getting shared mailbox up in your organization is the first step of using Office 365 Groups. Mostly
were so need isolated information and not a team work enabled. A case where SM makes sense
could be for example a “Support” or “Inquiries” Mailbox. It would be so nicely accessible as Office
365 Groups, but the advantage is a very easy way of replying “on-behalf” of incoming emails. That’s
why in those cases it is common sense using shared mailboxes.

9. Please don’t get confused with Resource Mailboxes, like you use for rooms or equipment.
Office 365 Group
Finally, we reached out to topic of this document.
An Office 365 Group is the best possibility targeting the following objectives:
- Team mail flow control
- Team consolidates mail thread tracking and tracing
- Team collaboration
- Team collaboration with external partners
- Team planning and tracking
- Team work space sharing
- Team work space meetings (Microsoft Teams)
See what Office 365 Group are about and where they are used.
Office 365 Group
Outlook
OneDirve
OneNote
Calendar
Skype
DynamicsCRM
Delve
Yammer
Teams
Azure AD Apps
Outlook - Group Mailbox shared
OneDrive - Group OneDrive, shared File Storage
OneNote - Group One Note for shared notes and team collaboration
Calendar - Group calendar with team member scheduling
Skype - Group for instant multi-IM-chats
CRM Dynamics - Group alignment between CRM and Non-CRM users
Delve - Group efficiency for activity analysis
Yammer - Group team new announcement and billboard
Teams - Group persistent chat and team meeting rooms
Those combined feature and tools enhance the private or personally owned resources and add the
additional team/ group work space in a joined model. All members can use those resources across
and make use for efficient team work.
Knowing exactly where to look for, access and track information and documents, furthermore share
their activities fast and efficient by at the same time saving valued resources of time and technology.

10. Important for business process consulting is that we are able to understand and clearly respect the
user privacy and team sharing areas.
Therefore, it is understandable the Office 365 Groups can simply enhance the team collaboration
capabilities, by adding shared workspaces.
This is the key subject reducing duplicated information, redundant files and complicated sharing’s
between team members personal resources.
My E-Mails
My meetings
My documents My Notes
Office 365 Groups

Remember:
Groups enhance the team’s capabilities and keep the personal workspace.
Challenges to be addressed:
Different Groups have different needs!
Chat-based
Workspace
Mail &
Calendar
Voice, Video
& Meetings
Co-Creating
Content
Sites & Content
Management
Enterprise
Social
Siloed Apps:
Multiple login to different non-interested applications, information discovery and sharing difficulties
Wasted Time:
Switching between apps is time consuming, redundant information itself and with in teams
Shadow IT:
Incomplete tool sets can force users look for their own solution outside the IT Enterprise boarders

11. Office 365 Group creation process
The creation process should be seen from tow side, the user creation by themselves and with the
central approach. But possibilities are having a strong impact on ROI calculations later.
Starting with the user own capabilities. Each group creation initiates the activation of the SharePoint
related resources, teams and planner. While the Group itself defines in Azure AD the identity,
SharePoint URLs, Group member list.
Once the process has been accomplished, the group experience is populated in app of choice.
If the admin centrally manages the groups, the process follows the same approach.
Best Practice:
A mixture of user and admin creation should be best. Where only several team leaders should be
allowed creating groups on their team needs. Admin therefore enabled groups on a global level. They
also need to control resource consumption and define possible quotas.

12. Office 365 Group ROI calculation
I will only redefect the learnings we have from “Wasted Time”, if we address security issues and
other areas, the costs an organization might have to bear could be incredible high.
As we understood from the chapters before, we can save time on each individual employee in an
organization and I will define a lower value, which might be closer to an average:
We assume a company with 100 users in the back office!
Saving
ROIT = -----------------------
total investment
Costs:
1000 User with total of 160hrs/mth and 11 month to work
average hourly rate 20€ and an average salary of 3.200€/mth
saved time per month is 2hrs (only)
Admin managing the resources in a defined mixed model = 6500€/mth
Admin costs over a year: 78.000,00 €
Total employee cost = 1000x 12 x3200 + 78.000€ (admin)= 38.478.000€
100 user save 200hrs -> 1000u x 2hrs x 20€ x 11mth = 440.000,00€
ROI within the first year:
ROIT = 440.000/78.000 = 564%
Therefore, the ROI is reached after approx. 2 weeks 😉
Now it’s time seeing how we configure those groups….
Note:
I will cover the Azure AD management of Office 365 Group only rudimentary in a dedicated chapter
https://docs.microsoft.com/en-us/azure/active-directory/active-directory-accessmanagement-
groups-settings-v2-cmdlets

13. Office 365 Group activation
Planning before creating
Understanding Office 365 Groups Limits
Office 365 has limitations in the count of groups and other resources.
- Each Office 365 tenant is limited to 500.000 Groups
- Each user is limited to 250 Group creations
- SharePoint Storage is in the limit of the tenant total amount of SharePoint storage
Beside this, we can address the file storage over usage issue simply by configuring quotas on the
Office 365 Group SharePoint Site.
WARNING:
Be aware, that creation of a new Task Planer already would create a new Office 365 group. So limits
could be reached easily within your tenant
Understanding Public or Private Groups
Within your organization / tenant, you either create a PUBLIC or PRIVATE Group.
A private group is not protected against non-member access. This should be the default value for
each new group, but can’t be controlled by admins on a global groups policy. You have, if you with
controlling this make use of the SharePoint permission concept. This needs to be trained and advised
to user who are allowed setting up groups.
If a Group is public, any request joining those groups is automatically answered with “approved”.
Note:
The default value of a Group is PUBLIC
Each group created is visible be default from your outlook online and desktop client, regardless is
private or public. If you wish hiding groups, you have to use the
HiddenFromAddressListsEnabled cmdlet and set it to ”True“.

14. Understanding Office 365 Groups Permissions
If you enable Office 365 Groups in your tenant, first all users are enabled for Group creation. More
worth, they are granted rights to the entire Group Site Collection (SP) and will be able change and
update documents.
One you limited the group creation to admin, member of the Group Owner groups are still granted to
those rights.
Understanding Groups Sharing Permissions
The rights sharing document with groups is the same with you OneDrive. You can simply do so, even
with Groups set to private. The outside sharing can be limited with in your tenant, which you might
do.
On the other hand, if you deploy RMS, you have the best approach to comply to company
compliance requirements.
Note:
Do always apply RMS with your tenant!
Understanding Office 365 Groups External Users & Collaboration
As mentioned above, as per default setting, Office 365 Group are enabled for external collaboration.
If you invite an external person, the Azure AD will have an internal entry for those persons defined.
Default, those external users will be threatened as internal for Office 365 Groups Make sure the right
are proper set for those external users!!!
Understanding Groups Storage
OneDrive is part of SharePoint as we know. But an Office 365 Group Site Collection will not appear in
f the central SharePoint Online Administration. This has an significant impart, it simply can’t be
managed for the SharePoint Web GUI via the user interface.
This could impact your SharePoint Storage contingent if you don’t plane for Group Storage Usage.
You can limit the storage size via the Set-UnifiedGroup cmdlet.

15. Create an Office 365 Groups Permissions
Office 365 Groups SharePoint Site
First, we create an Office 365 Group directly from SharePoint.
Navigate to SharePoint and click.
Next you have to create a “site”.
Name and define the Group.

16. Define the Owners and Members Group.
Your Group with all feature will be setup in a couple of minutes.
From here you can further configure your team site in SharePoint and manage the group.

17. Office 365 Groups Admin Portal
Open you tenant Admin Portal and maneuver to Groups.
Create the Group as usual.

18. If the Group should be able receiving Email from external, you need to activate this in the group
properties.

19. Office 365 Groups Exchange
Navigate to the Exchange Admin Portal/ Recipients/ Groups
Create the Group

20. You can manage even like with a shared Mailbox, your Send As and Send on Behalf permissions.

21. Office 365 Groups Organizational Settings
Go to you tenant Service & add-ins and define the outside access permissions
Office 365 Groups Settings in Outlook
If you are the Group Owner, you can modify your Office 365 Group.

22. Guest access in Office 365 Groups
How it works
Office 365 users can use Outlook on the web or Outlook 2016 to add and manage guests in
their Office 365 groups. Guests can have any email address, and the email account can be a
work, personal, or school account.
• Step 1 A group owner adds a guest to the group or a guest is nominated by group
members. The group owner approves the nominees.
• Step 2 The group owner is informed of what the guest can access within the group.
A combination of text and icons give all group members clear indication of guest
participation.
• Step 3 The guest receives a welcome email and can participate in group
conversations, receive and respond to calendar invitations, and access the group
files.
• Step 4 Guests can leave the group at any time via a link in the footer of all group
emails and calendar invites.
Guest access is a tenant-level setting and is enabled by default. A tenant admin can manage
the guests and their access to Office 365 group resources using PowerShell. See Allow
external people guest access to Office 365 groups for instructions.
The guest experiences
When a guest is invited to join a group, they receive a welcome email that includes a little
information about the group and what they can expect now that they're a member.

23. Managing Office 365 Groups with PowerShell
With Azure AD
Uninstall-Module AzureAD
Uninstall-Module AzureADPreview
Install-Module AzureADPreview
Connect-AzureAD -> enter your tenant admin
Get-AzureADGroup
With Get-AzureADDirectorySettingTemplate, you will see the Configuration Templates for
Unified Groups (Office 365 Groups)

24. Next we want to see the Group Settings:
$Template = Get-AzureADDirectorySettingTemplate | where {$_.DisplayName -eq
'Group.Unified'}
$Setting = $Template.CreateDirectorySetting()
$Setting.values
For example, changing the “EnableGroupCreation” gloably to “false” follow the next steps
Get-AzureADDirectorySetting
$setting.values
$setting.values["EnableGroupCreation"] = “false"
Set-AzureADDirectorySetting -Id d634c419-bde2-4ebb-880e-a1dc4a1904cb -
DirectorySetting $Setting

25. With Exchange PowerShell:
Connect remote PowerShell to Exchange Online:
$exchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -
ConnectionUri "https://outlook.office365.com/powershell-liveid/" -
Credential $credential -Authentication "Basic" -AllowRedirection
Import-PSSession $exchangeSession -DisableNameChecking
Get-OwaMailboxPolicy | FL Name
Set-OwaMailboxPolicy -Identity ‘OwaMailboxPolicy-Default’ -
GroupCreationEnabled $true
Get-OwaMailboxPolicy | FL Name, GroupCreationEnabled
What can be controlled:
1. Naming Policies
o Blocked words
o Pre / Postfixes based on Active Directory attributes
2. Creation restriction
3. Dynamic membership rules. (i.e. all Marketing users should be member of “Marketing” Office
365 Group)
4. Group Policies
o Show and inform users about the organizational “Groups usage guidelines”
o Data Classification
▪ Labels such as internal, external or confidential
o Hidden Memberships where only members can see other members
PowerShell cmdlet’s managing Office 365 Groups
Get-UnifiedGroup
New-UnifiedGroup
Remove-UnifiedGroup
Set-UnifiedGroup
Add-UnifiedGroupLinks
Get-UnifiedGroupLinks
Remove-UnifiedGroupLinks
Refer to the Hyper-Links for each cmdlet and configure the property you are required.

26. Getting the configured Groups:
Get-UnifiedGroup
Get-UnifiedGroup -Identity sfbdach | fl *name*,*group*,*email*,*access*
Configuring settings on a group:
Set-UnifiedGroup -Identity "TestGroup" -PrimarySmtpAddress
TestGroup@domain.com -RequireSenderAuthenticationEnabled $false -AccessType
Private
Handling members and owners:
Get-UnifiedGroupLinks -Identity sfbdach -LinkType owner
The LinkType could be: Members | Owners | Subscribers | Aggregators

27. Office 365 Teams
The new Office 365 feature called TEAMS requires an associated Office 365 Group. Without it will not
work.
Both, Groups and Teams a very powerful set of tools to users. They influence our way of work
massively and enable us work even more efficient than with Groups alone. We still need some
planning our Teams and for sure the business process impact. We want then enabling business not
disabling.
We need to ensure these key areas are covered:
• Governance
• Security
• User education
• Data management (duplication and versioning)
• Lifecycle
Office 365 Teams consideration
Some thought we have and I list them down here:
Do we want both or only Group, just a mixture is the right approach in your business? The interaction
of both need to be remembered.
1. Creating a Team will always create an Office 365 Group, with all additional resources (e.g.
team site, OneDrive and more)
2. If you create a Team, better connect it to an existing Group (this could be done by the group
owner)
3. Group Merging do only support (Files and Calendar), conversation and chats are not able to
be merged yet
4. A Group’s OneNote will not be entirely displayed in a Team, only the associated sections for
each channel
5. Group Planner is not accessible from Teams interface. Team Planner task created in
separated Teams channels will not show up in Group Planner
6. Teams File Storage is not synced with the Groups File Storage!
7. In Teams you can only see OneDrive Storage, if you add the URL as a SharePoint tab
8. No file/ content could be recovered (yet) when deleted in Teams
If this was a file under the SharePoint tab, its recoverable with SP (Groups)
The Teams limitation goes along with Office 365 Groups, 500.000 tenant-wide and 250 per user each.
A Team can have up to 10 owners and 999 members. 20 members can be in a private chat and max.
80 members in meeting.

28. Office 365 Teams tenant activation
You need to go to your Admin Portal under Setting/ Services& add-ins.
From here you global enable or disable TEAMS, as well as all the individual organizational setting.

29. I’m not going deeper into the Tenant-wide and user settings. They are very much self-explaining and
make the global setup much easy.
Create Office 365 Teams (with new Group) from the scratch
Start your Teams client.
From here create your TEAM incl. the Office 365 Group.

30. Add you team members, remember, you are still the owner
After you added the team member, you can decide if he is a owner or still a member
You are done!

31. Create Office 365 Teams with existing Group
Follow the same process like above, but chose the “Yes, add Microsoft Teams functionality”, this
adds the Team to an existing Office 365 Group
All exiting Office 365 Groups are provided where you can create a Team from.
Finally, we have two TEAMS created

32. Create Office 365 Teams Channel
The following options let you create channels within your Team, and more option, which are self-
explaining.
Add you channel name and description

33. Office 365 Teams further options
In Teams you can add several types of documents or other apps, even BOTs which you can write
answering common question in team. Planner, SharePoint and WebSite are interesting, with the
focus on SharePoint
Office 365 Teams - Adding a SharePoint OneDrive File Storage
As we know, OneDrive is the SharePoint document library and one of those we will add now.
Click the “+” Symbol and than the SharePoint App.
Instantly the SharePoint based OneDrive will be found from all exiting Sites Documents.

34. Pick your document library:
Provide a name for the new tab.
It takes a couple of second and the SharePoint view will be provided in your TEAMS

35. Office 365 Teams – Plan a Team Meeting
As you will soon see you Teams as an important workspace, you will work with on a daily basis.
Scheduling Team Meetings is straight forwards.
Define the topic, the Meeting Team and Channel, Time. You are also able to schedule reoccurring
meetings.
Next go and select the meeting recipients required to attend

36. One part I like more than in Skype for Business is, that the meeting has it limitation. So you CAN’T
join earlier and its restricted. Similar as we know it from WebEx.
Have fun playing with your TEAMS and OFFICE 365 GROUPS.
I believe you see a huge value and potential collaborating much
more efficient than before.
