If you open calendars in "People's Calendars" other than "My Calendars," it
corrects the problem.

Any luck on finding a solution. I have not found a solution to this problem
either. We have secretaries that need to have full permissions on certain

The problem lies with the permissions on the mailbox... if you are delegated (tools-options-delegates) only on the calendar it works fine...but as soon as they give you permissions on the complete mailbox, printer assistant will duplicate your calendar...haven't found any solution yet though...
