I'm having a similar problem with one of my mailboxes The inital error reads
\\NCS1\Microsoft Exchange Mailboxes\~~~Mailbox Name~~~?Top of Information Store?Inbox~~~lots of kanji characters~~~ Outlook Message Manager (Outlook) (KEY: BA4FC0B3F72B1146BD40CD1E3CB737E9)" is a corrupt file.
If this is caused by a corrupt attachment, how do I determine which email message needs to be deleted? By sorting the backup by size I've determined that the message is around 400 bytes long but a review of all messages in the user's inbox of similar size turned up nothing. I was able to find the messages shown by the backup to be just smaller and just larger than the corrupt message, but no messages were shown in the inbox with a subject of "Outlook Message Manager" or of the appropriate size.Message was edited by:
