I have a user who is receiving the following error on their Outlook 2007 mailbox.
"Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachements and images from unsent messages you are composing."
There are no administrator set policies, group policies, settings or anything that would cause this as far as I can see. The user is a member of a group/organisation unit that has 4 other users in, they do not receive this error.
Having googled this error I have tried applying the hotfix described in http://support.microsoft.com/kb/970944/
and Disabling the session limit by setting the following value to 1 on the exchange server.
Value: Disable Session Limit
Neither of these solutions solved the issue!
