Yes, I set the source folder to have local storage (also called store for offline use) and did the copy. You're right, it does seems stuck at 1 but the copy completes much faster. This may mean when you do the copy, the messages are being fetch from imap first. This should indicate that you did **not** have local storage for the source imap folder. Before you did the offline copy, did you set the source folder to have offline storage? Anyhow, maybe an IMAP:5 log would be helpful if the corrupted messages are coming from the imap server.

This may mean when you did the online copies, the messages are being fetch from imap first. This should indicate that you did **not** have local storage for the source imap folder. Before you did the offline copy, did you set the source folder to have offline (local) storage and then download the folder? This can be done using the right-click properties menu under synchronization Anyhow, maybe an IMAP:5 log would be helpful if the corrupted messages are coming from the imap server which I is being to sound like. Yes, tomorrow maybe an imap log would help: see https://wiki.mozilla.org/MailNews:Logging
