"New-TransportRule -FromMemberOf" fails because object can't be found

Iron Contributor

I'm trying to create a transport rule (Exchange Online) to add an image to outgoing emails where the send is a member of a certain group.


I've created the group in AD and performed a delta sync to AAD. I've verified that the group was successfully synced.


Is this possibly a timing issue within Office 365?


Here's the full error:


Couldn't find object "Transport Rule - Banner Type 1". Please make sure that it was spelled correctly or specify a different object.

(That's funny. Looks like this forum's emoji parser could use a little TLC.)

The group needs to be 'recognizable' by Exchange. You cannot use a regular security group, it needs to be mail-enabled. Or a simple distributiongroup. In other words, it should appear in the list you get with Get-Group or Get-Recipient.

Thank you. That did it.

On my Exchange server:
PS> Enable-DistributionGroup -Identity $GroupToMailEnable
