Question

Unauthorized when using Add-DistributionGroupMember to add user to Exchange managed Distribution

Shawn Imholte 20

I followed the steps in this article https://learn.microsoft.com/en-us/powershell/exchange/connect-exo-powershell-managed-identity?view=exchange-ps&WT.mc_id=M365-MVP-9501 to use my Azure Automation System managed identity to connect to ExchangeOnline but when I use the CmdLet Add-DistributionGroupMember I get an Unauthorized exception. I tried adding the -BypassSecurityGroupManagerCheck flag but it still comes back Unauthorized. I followed Step 5 in the article mentioned above so that Identity is already an ExchangeAdministrator. What other permissions does that user need?

Hi,@Shawn Imholte

Thanks for posting your question in the Microsoft Q&A forum.

Based on your description, you are using Azure to host Exchange Online. i am not sure if it is Azure that is affecting the use of Add-DistributionGroupMember. Can you describe specifically how you are using Add-DistributionGroupMember? It is recommended that you disconnect Azure Hosted Exchange Online first and only run commands in Exchange Online PowerShell.

I'm using a Runbook in Azure Automation, I'm simply trying to automate on-boarding new employees into the organization by providing some simple functions. With error handling and params removed my code is simply

Connect-ExchangeOnline -ManagedIdentity -Organization XXX Add-DistributionGroupMember -BypassSecurityGroupManagerCheck -Identity

hi，@Shawn Imholte

It's nice to hear back from you.

Based on the information you provided, I checked the official documentation and found that special permissions are required to use BypassSecurityGroupManagerCheck.

Suggest you check if you have access to your account and if not add it on.
