Hi,@Rising Flight

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

Based on your description, you seem to be experiencing permission issues.I checked the official documentation, which provides two solutions.1.You may lack the following permissions:

2.Add yourself to the attribute ManagedBy

You can refer to this link for the exact method:https://learn.microsoft.com/en-us/exchange/troubleshoot/groups-and-distribution-lists/no-sufficient-permissions-moving-dg?source=recommendations

Currently, user1 is the owner of the group mesg1@contoso.com. I want to add user2 as an additional owner, so that both user1 and user2 are owners. Which of the syntaxes below will work?

Update-DistributionGroupMember -Identity mesg1@contoso.com -ManagedBy @{Add="user1@contoso.com", "user2@contoso.com"} -BypassSecurityGroupManagerCheck or Set-DistributionGroup mesg1@contoso.com -ManagedBy @{Add="user1@contoso.com", "user2@contoso.com"} -BypassSecurityGroupManagerCheck

hi,@Rising Flight

I'm glad to hear back from you.

To add an additional owner to a distribution group in Exchange, you would generally use the Set-DistributionGroup cmdlet. Between the two syntaxes you provided, the second one is the correct approach to add an additional owner:

Set-DistributionGroup mesg1@contoso.com -ManagedBy @{Add="user2@contoso.com"} -BypassSecurityGroupManagerCheck

Here is my testing process:

1.The DL currently has only one owner.

2.Run the second command to add the owner.

Use powershell and bypass the manager requirement

https://learn.microsoft.com/en-us/powershell/module/exchange/update-distributiongroupmember?view=exchange-ps

Update-DistributionGroupMember -Identity "Research Reports" -Members chris@contoso.com,michelle@contoso.com,laura@contoso.com,julia@contoso.com -BypassSecurityGroupManagerCheck
