I have a similar problem. We have Outlook 2007 and WinXP SP3. About 3 weeks ago, we could print a range of 12 months. Now we can only print 2-month ranges. When you select any 3 months, Outlook "protests" and closes. We can, however, print any one month at a time, but that is time consuming. The printing of ranges errors out whether we print the Outlook Calendar to a regular printer, or if we print CutePDF into an Adobe PDF file. We also tried looking at the WEEKLY view, but print to the MONTHLY view -- the error persists. There are no disable add-ins. If you suggest we delet outlprnt, I am unable to find that file anywhere.
