Microsoft Teams PowerShell

Poweshell is simply amazing , it saved more than 3000 hours in my life. It made the impossible possible to work with Microsoft Products seamlessly. when it comes to managing large data sets or user base. It makes life simply easy. Microsoft Teams dynamic membership can happen only on the team level with Azure P1 license . But if you wish to have channels with large user base. PowerShell is your savior.  Otherwise your fingers are going to pain clicking it.  i have made as simple as possible using the existing cmdlets . if you wish to add any additional cmdlets please feel free to leave on comments.

  1. hey im curious if its possible to use this module to directly manipulate chat conversations or if such a module exists. Specifically Im hoping to clear out conversations older than a specific age.

  2. Hi, I followed the instructions step by step, but I have this error message:
    Get-TeamChannelUser : The term ‘Get-TeamChannelUser’ is not recognized as a cmdlet name, function, executable program or script file. Check the spelling of the name or verify that the path is included and correct, then try again.
    In riga:1 car:1
    + Get-TeamChannelUser
    + ~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : ObjectNotFound: (Get-TeamChannelUser:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

    Can you help me ?
    thankyou !

  3. This was very helpful. I am receiving an error “BadGateway” when I attempt to modify your script to include “Role”. Am I doing something wrong?

    Import-Csv .\addChannelUsers.csv | ForEach-Object{Add-TeamChannelUser -GroupId $GroupId -DisplayName $_.cdisplayname -User $_.cuser -Role $_.crole}

  4. Display All Teams and Channels – Get-Team | ForEach-Object{Get-TeamChannel -GroupID $_.GroupID | FT DisplayName,Description,MembershipType}

    How do I export to CSV? I added Export-CSV but it doesn’t show all the info as it does when listing on PS. I’d like to export all Teams channels/groups their owners and members for each channel.
    Pls help! Thx!

  5. Hi, Satheswaran,
