This Question has been asked before for Outlook 2003 SP2. Which was solved by this hotfix (http://support.microsoft.com/kb/920061
. We upgraded to SP3 2 weeks ago and this error message is back again.
Outlook 2003 SP3, when accepting an appointment, users are getting the following message:
"The function cannot be performed because the message has been changed"
This is not wide spread but its happening to enough users that I need to find an answer quickly.
All of the users are on Outlook 2003 SP3. Some of the invites are sent from delegates. Any assistance is greatly appreciated.
