Need better way than "delete .msf file manually" in order to force re-fetch of mesaege header and message body for maildirstore/IMAP/Offline-Use=On folder, if design of "Repair Folder" in maildirstore/IMAP is changed from berkleystore/IMAP.

Just an idea.

(A) Per folder "Re-fetch of all message headers".
    "uid xx fetch body[headers]"
    + comparison of all header lines with content of cur/nnnn file
      (uid xx fetch body[], if header is different)
    + current "Repair Folder" in maildirstore/IMAP/Offline-Use=On
      (reparse message headers held in Mbox/cur/nnnn file)

(B) Per mail "Re-fetch of entire message data".
    Similar to current "per mail Undelete" in mail context menu
    for "mail marked as deleted" with "Just mark it as deleted".
      Set Offline=false in msgDHdr.flags
    + delete Mbox/cur/nnnn file
    + msgDBHdr.setStringProperty("storeToken",null)
    + nsIMsgImapMailFolder.downloadMessagesForOffline(),
      or force message re-display(no local mail data, then fetched)
      => uid xx fetch body[] => saved in Mbox/cur/nnnn
      => return to Offline=true in msgDNHdr,
                   StringProperty of storeToken=nnnn
