+Normally, when you copy a message between folders or add a
+new message to a folder locally, OfflineIMAP will
+just do the right thing. However, sometimes this can be
+tricky -- if your IMAP server does not provide the SEARCH
+command, or does not return something useful,
+OfflineIMAP cannot determine the new UID of the
+message. So, in these rare instances, OfflineIMAP will
+upload the message to the IMAP server and delete it from
+your local folder. Then, on your next sync, the message will
+be re-downloaded with the proper UID. OfflineIMAP
+makes sure that the message was properly uploaded before
+deleting it, so there should be no risk of data
+loss. |
