Do you know how to locate the message by it's ID?
No. AFAIK there is no way to find the exact message by ID.
Run the script to export as MBOX files. When the script runs it makes a
folder on you desktop named Entourage Archives. After you start the script,
go to the Finder and click on the folder so you can watch it create the MBOX
files of your folders. The script will fail on the folder with corruption.
Note the last folder that was created.
[Note also open the Activity Monitor while the script is running. The
Microsoft Database daemon will be active. When it goes back to normal, you
know the script has stopped running.]
Once you know where the first folder is that has a problem message, divide
the folder in half and manually drag each subfolder to the desktop. This
will fail if the folder contains a corrupted message. Often you have to make
several subfolders to get to the corrupt message. When you narrow it down to
a small number, you drag out individual messages. Often it will show up OK
in Entourage but will fail to drag as an individual message. Sometimes it
will even drag out, but will open as corrupted data. Delete the bad message.
Then start the MBOX script again until you get out all folders as MBOX
files. If this is successful, try the autoarchive script again.
Export folders as MBOX files (includes subfolders)
