we have setup Exchange 2010 in co-existence with Exchange 2003 and are in the process of migrating everything over.
My question relates to Distribution Groups.
I have a distibution group named All Staff and the recipient type is Mail Universal Security Group.
If I try to change a member of the group I am faced with a Microsoft Exchange Error stating 'you don't have sufficient permissions. This operation can only be performed by a manager of the group (Set-DistributionGroup).
If I go into Group Information there are no settings shown for Managed by.
What do I need to do in order to recitfy this problem.
