We have recently completed the exchange migration from 2003 to Exchange 2010. Prior to the migration, users were able to manage distribution lists and add/remove users in distribution list. Also all users were able to update their own information (cell phone number, etc) however since migrating to exchange 2010, all of these areas are greyed out and no one can make any changes.
All mailbox and distribution list are now on exchange 2010, outlook version is 2007 or 2010.
Any suggestions on how to get back this functionality is greatly appreciated.
