Outlook hangs when moving from message to message in the In Box or from the In Box to the Calendar. I have run Scanpst several times. Rebooted seveal times. I looked at Event Viewer/Applications and found the errors. The description is different for each error and is unintelligible to me. For example the most recent description reads:

"The description for Event ID ( 0 ) in Source ( Broadcom ASF IP and SMBIOS Mailbox Monitor ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: !ERROR 53 Refreshing BMAPI data."

The prior description reads:
Fault bucket 467407681.

Prior to that:
Hanging application OUTLOOK.EXE, version 11.0.8169.0, hang module hungapp, version 0.0.0.0, hang address 0x00000000.

Prior to that:
Fault bucket 467407681

The first error description was:
Hanging application OUTLOOK.EXE, version 11.0.8169.0, hang module hungapp, version 0.0.0.0, hang address 0x00000000.
