Hi there,

done the install of Sp1 just over a week ago and all went great. However, since then I seem to have lost permissions to do various things.

For example, I can create a new mailbox but can't add the mailbox do a distribution group! even trying to remove a member from a group gives me an error. (see below)

Microsoft Exchange Error
The following error(s) occurred while saving changes:

You don't have sufficient permissions. This operation can only be performed by a manager of the group.

To add/remove members I have to do it in AD!

Anyone any ideas?
