for information protections
• Group property updates
• Group manager changes
• Group member changes
• Group hard delete
• User property updates
• User hard delete
What’s behind when a Team is created ?
• A SharePoint Online Site is created
• Team mailbox is created (exchange/sharepoint)
Operations performed on
Groups are synched to Microsoft
Teams
AAD Microsoft Teams
Teams persistent chat is
provided by a chat service that

28. CASE SCENARIOS

29. • Enumerated content data and applicational assets
• Identified archive & useless content
• Plan : POC, Business user sponsors
• Reorganized content
• Migrate >Validate > Deploy
CASE SCENARIOS

30. Constraints:
• Client don’t want to open teams creation
globally, but in a contained manner
• No API for Migration to Microsoft Teams
and migrations are not supported
Context:
Multinational clients with >5TB of information
Leveraging Microsoft Teams for internal and external users
CASE SCENARIOS

31. Open teams creation in a contained manner:
• Enable group creation to a specific security group
PowerShell...
Connect-AzureAD
$Template = Get-AzureADDirectorySettingTemplate | Where-Object {$_.DisplayName -eq 'Group.Unified'}
$Setting = $Template.CreateDirectorySetting()
New-AzureADDirectorySetting -DirectorySetting $Setting
$Setting = Get-AzureADDirectorySetting -Id (Get-AzureADDirectorySetting | Where-Object -Property DisplayName -Value
"Group.Unified" -EQ).id
$Setting["EnableGroupCreation"] = $False
$Setting["GroupCreationAllowedGroupId"] = (Get-AzureADGroup -SearchString "AllowGroupsCreation").objectid
Set-AzureADDirectorySetting -Id (Get-AzureADDirectorySetting | Where-Object -Property DisplayName -Value "Group.Unified“
-EQ).id -DirectorySetting $Setting
CASE SCENARIOS

32. Migration to Microsoft Teams
CASE SCENARIOS
• No API was available for teams management
Not really state of the art … but it works:
• Screen scraping PowerShell managed scripts to create
teams for the migration
• Afterwards, migrate content to teams using usual
SharePoint Online migration tools

33. • Managed PowerShell script for team creations
PowerShell...
….
$ie = new-object -ComObject "InternetExplorer.Application"
$ie.Visible = $true
$ie.navigate($siteUrl)
while($ie.document.body.outerHTML -notMatch $elementToCheckifDOMisLoaded) {start-sleep -m $sleepTime};
## while( $ie.ReadyState -ne 4 ) { Start-Sleep -Milliseconds $sleepTime }
start-sleep -m $sleepTime
…..
$ie= OpenSite -ie ([ref]$ie) -siteUrl https://teams.microsoft.com -elementToCheckifDOMisLoaded "picture-load" -sleepTime 3000
$createTeam = @'
var content = $("[aria-label='Teams Toolbar button']");
$("[aria-label='Teams Toolbar button']").trigger("click")
$("[track-summary='Add Team']").trigger("click")
$("[translate-once='icons_team_create']").trigger("click")
'@
$result = ExecJavaScript $createTeam
Start-Sleep -Milliseconds $sleep
….
CASE SCENARIOS
http://bit.ly/MsTeamsPSModule
Alternative : PowerShell module for
Microsoft Teams using the rest API *

34. During the implementation, some of the problems we come across
CASE SCENARIOS
• Teams created with 2 site collections associated to it
Resolution: Delete Team + Recreate the team
• Teams created but with no site collection provisioned
Resolution: Create an Office Group; Promote it to team
• Users can't recreate a pre-existing channel name
Once a channel name has been created, even if it's deleted, it cannot
be recreated.
By renaming a channel, folder in SharePoint remains unchanged
Avoid renaming channel associated folders

35. During the implementation, some of the problems we come across
CASE SCENARIOS
• List of workspaces is not alphabetized
Users switching workspaces when adding a PowerBI tab will encounter
an unalphabetized list of workspaces to switch between.
• A team name with an & symbol breaks connector functionality
When a team name is created with the & symbol, connectors within the
Team/Group cannot be established
Resolution: recreate the team
• Can't save profile picture
Users can't save their profile picture when the Exchange Mailbox is
hosted (homed) on-premises.

36. Be Aware off …:
• No API to actually create object as is from one place to another
• Conversations migrated using rudimentary exportimport (html)
• Conversations cant be recreated as is
• PowerShell API (supported by MsGraph) not aligned with the DesktopWebClients
• Some Teams Features structure with continuous updatesreworks
