[urgent] Add bulk external users via powershell to Microsoft Teams

Question

Adding bulk external users to teams and check if they already exist in the team for the specific group and need help in implementing using powershell

Answer 1

AFAIK, This is possible through the Graph API.
To bulk add users to your team, the most recommended way is to create an office365 group or distribution list by your admin. Once you have those members in it, at teams client, instead of adding individual members, you add to as group, so you could achieve adding multiple users at the same time.

If you need to using PowerShell command to add team users, you could refer to https://learn.microsoft.com/en-us/powershell/module/teams/add-teamuser?view=teams-ps.

For importing the csv file to create a new dg, we need to use a PowerShell command as below:

Import-Csv “D:\list.csv” | foreach{Add-DistributionGroupMember -Identity “GroupName” -Member $_.alias}

Please replace “GroupName” with your actual distribution group email address.

Answer 2

Hi @sweetu ve ,

You need to invite the external user first. You can do it via the Azure AD module.
