I have imported a large archived message file from a backup storage location.
The mailbox name is not one of the OE default names, it's my own creation.
The import seemed to be successful with the mailbox name showing up in the OE
left pane folder list.

There were several thousand messages imported although the file size is only
about 400mb.

However when I try to open the folder to look at the messages, OE shows a
percentage loaded status indicating that messages are being loaded into the
maibox, but as soon as it reaches 100%, OE just shuts down completely.

Is there anyway to fix this problem?
