Can anyone help? I have a corrupt Calendar Navigation Pane in my Outlook 2003 Professional. It does not display any dates in the monthly calendars in the navigation pane. I see the frame for the calendar (with a holder for each date) but nothing at all in the date fields. I have tried de-installing office and re-installing, this hasn't solved it. I have tried the repair utility on the PST files, I have tried running Outlook.exe with the /CleanFreeBusy option, I have tried re-creating extend.dat, Outcmd.dat and Frmcache.dat, but still nothing works. I am so frustrated now, that I have just de-installed Office and IE7 and then re-installed both, but I still have the same problem! I have run out of ideas! Can anyone help? It is incredibly frustrating!!
