When in Outlook 2003 for Windows, I am getting this bizarre error when my users are trying to print someone else's calendar ...

The messaging interface has returned an unknown error. If the problem persists, restart Outlook.

... restarting Outlook often has no effect. Sometimes, changing a style in Page Setup first, then exiting, and restarting the program will result in the ability to print in the new style (Daily/Weekly/Monthly styles, e.g.), but this behavior isn't consistent. I have one user limited to only Monthly style, with any attempt to print any other style resulting in the above, goofy error. On the other hand, I have another user that will get the error when printing a Daily style, but if changed to Weekly in Page Setup, exiting the program, and then re-entering the program, Outlook will print fine in the Weekly style.

There appears to be no problem when printing their own Calendars. One of the end-user Calendars is local which she doesn't need to print (her own), but most of these reside on the Campus Exchange Server. All the printers are on queues. No one is printing directly.
