Hi Readers,

This is also a unique issue that we faced after migrating users to exchange 2010

Secondary Owners  are not able to edit Distribution Lists, These secondary owners have write-members permission &

It was working perfectly in Exchange 2007 & Outlook 2010.

But now its kind of broken so solution is: As exchange 2010 allowed multiple users in managedby field therefore

We have done below to resolve our issue:-

• Check who is the current owner?
• Whom do you want to add as backup owner?

Owner(user1) should be first in sequence & Backup owner(user2) should be second.

Set-DistributionGroup “name of Distribution List” -ManagedBy “User1”,”User2” –BypassSecurityGroupManagerCheck

This resolved the issue for us.
