PowerShell Script that updates Distribution Groups - JSON error

Patterson, Cody L 0 Reputation points

I have a PowerShell script that updates AAD distribution groups. Periodically, I will get a JSON error when doing the update

Here is the PowerShell command that I'm using. I have checked the IDs that are getting posted and none of them seem to have any incorrect characters in them.

Update-DistributionGroupMember -Identity $dgalias -Members $UserList -Confirm:$false -ErrorAction Stop    

I have attached the error as an image as it would not let me paste it in the text field.

    Are you getting the same type of errors when connecting via the old, RPS-based method (i.e. Connect-ExchangeOnline -UseRPSSession). If not, best report this directly to the team at RPSdeprecation at service.microsoft.com.
