Have been running Exchange 2003 Version: 6.5.7638.1 without problems on Server 2003 SP2. PC having the issue is running Win XP Pro SP3 and Office 2007. For months the PC was fine. The one day it stopped getting the calendar information. On the PC when Outlook is started, message comes up "Could not read the calendar", and every 15 minites or so downin the task bar message pops up '"MS Outllok - could not load personal free/busy data"".

The first thing to do is exit outlook and find the .OST file being used by the Outlook profile (even if the OUtlook profile isn't set to use Exchange cached-mode). Then delete the .OST file and start Outlook with the "/Cleanfreebusy" switch. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

It tells outlook to republish the calendar information in the F/B public folder (if you use public folders). --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
