There are multiple recipients matching identity. Please specify a unique value #41

Hi, Just been using the script to migrate a Mail-enabled security group, the migration fails with the error ‘There are multiple recipients matching identity "Department of Engineering". Please specify a unique value.’

2 other groups are (not mail-enabled) are being synced already with the same display name.

Any recommendations on a workaround?

Hello - please download the lastest version.

Code was changed to stop using mailNickname after it was determined that mailNickName does not have a unique constraint. Now when the DL is created we automatically update the post create configuration - and use the externalDirectoryObjectID for each call from that point forward.

That should eliminate this moving forward.

Confirm that you updated from the powershell gallery? I ask because I had a other customer with the same yesterday but it was still using older module code. If so please send me the full log @.***

Hi! Ok thank you for posting this.

So I went through and took some more changes. The first was to also move the unambiguous DL creation into new DL. So it looks like new DL, set DL etc all trip up when there's other things that come close to matching across all attributes like name / alias / etc.

So now the code creates a generic blank DL - then later on renames it which eliminates all collisions. The set operations now use externalDirectoryObjectID - which allows it to reference the exact group that was created.

Can you try this new build 2.5.14.1 and advise?
