(In reply to Geoff Lankow (:darktrojan) from comment #32) > If we know it's an IMAP folder we're compacting, and we come across what we think is a corrupt message, clearing the offline flag should be enough to trigger a new download once compaction is complete, no? No. Downloading a new copy of a corrupted message doesn't resolve the issue, because it doesn't fix the bad data at the beginning at the message file. As long as we have non-"From " data at the beginning of the file, compact continues to fail with that error message.
