I have read with interest some posts in which Outlook calendar can be fixed by running the \cleanfreebusy switch. We have 2 users out of over 200 whose calendars cannot be viewed properly - even from the exchange server admin account. We are running mainly NT4/Office97. Rebuilds of PCs and profiles hasn't fixed the problem, but strangely a few of our admins who are running Win2k/OfficeXP seem to be able to view the suspect calendars with no trouble. If I ran the switch on the server Outlook through an admin account, does it repair and regenerate calendar items (as I have been led to believe) or does it wipe out everything (initialise)? Alternatively does anyone know what else could be wrong?
