Don't know since you conveniently forgot to mention your version of Outlook
and when this began happening (e.g., what you installed/uninstalled/updated
just prior to it starting.)

After furious head scratching, Joe asked:

| When I try to switch to tab Scheduling in the Meeting, the Outlook
| always crashed and exit. Running debug, the message "Unhandled
| exception in Outlook.exe (MSPST32.DLL) : 0xC0000005 : Access
| Violation".
|
| How can this be fixed?
|
| Thanks.
