I have one new lapotp that is running outlook 2007 connected to Exchange 2003. When Shared Calendars are being viewed from Exchange on this laptop no appointments are displayed. I also logged in with my domain account and the appointments are not there. I see them on my laptop but the same user, logged in to his old laptop and can not see them there either. This lead me to believe the OST or PST file was corrupt. I ran the ScanPST.exe on the OST and PST files which found errors but after the scan the problem still exists.
