Hi @Rising Flight

Use the Add-TeamChannelUser cmdlet, or the corresponding Graph API endpoint: https://learn.microsoft.com/en-us/powershell/module/teams/add-teamchanneluser?view=teams-ps Here's a quick example on how to bulk add via CSV:

Copy

Import-Csv "blabla.csv” | % {Add-TeamChannelUser -GroupId GUID -DisplayName "channel name" -User $_.UPN}  

where the CSV has a column called "UPN" to designate the users

I am getting below error.

Add-TeamChannelUser : Cannot bind argument to parameter 'User' because it is null.

Add-TeamChannelUser : Error occurred while executing Add-TeamChannelUser

Message: Invalid User Id.

i have used my csv files in the below 4 formats

EmailAddress
user1@contoso.com

EmailAddress
user1

UPN
user1@contoso.com

UPN
user1

i have used the below syntaxes but stil i am getting error.

Import-Csv "C:\temp\input.csv" | % {Add-TeamChannelUser -GroupId 111111-1111-1111-111-1111111 -DisplayName "test1" -User $_.UPN}


Import-Csv "C:\temp\input.csv" | % {Add-TeamChannelUser -GroupId 111111-1111-1111-111-1111111 -DisplayName "test1" -User $_.EmailAddress}
