I have a client that use Outlook 2003 on a Win XP Pro system up till now was able to move calendar item with a mouse between shared calendar and his own calendar. Now when he tries to drag a calendar item there is a circle with a slash thru it and it will not allow him to copy the calendar item any where using a mouse. I've tried login in on another system and create a new profile on it and still the same problem. All of the other users connected to the shared calendar are able to move calendar items. This has to be on the Exchange 2003 because login on a different PC had the same problem.
Is there a way to reset permissions on the shared calendar or will i need to delete and recreate a new calendar?
