We are running Exchange 2010 and just found out that users are unable to modify a Dist. Group from Outlook client like they were able to do in the past. We have a user that would like herself and her team to modify email groups and from what I have read since 2010 they feature is off by design with in the Outlook client. Back in the day (its been awhile) we use to choose a group in Outlook and modify the users in there no problem but after Exchange 2010 that feature throws an error which I have attached. I was doing some research and there are workarounds but we want to know what Microsoft suggest we do to allow a group of users to modify DG again with in Outlook. I am sure many others have ran into this and wondered if they found a easy way to allow this again. We don't want to give these users to AD just to make the changes.
