I then went online to sync the folders and I couldn't find the e-mail anywhere. It wasn't in the local folders and it wasn't synced to Google. Reproducible: Always Steps to Reproduce: 1. Go offline by clicking light bulb 2. Drag messages to GMail folders 3. Go online 4. Search for dragged messages. Actual Results: E-mail is missing. Expected Results: 1. E-mail should by synced when going online. Failing that; 2. UI should prevent dragging to offline IMAP folders.

I cannot reproduce this. I followed the listed steps, and the dragged messages were uploaded when I went online.

WORKSFORME, with Tb trunk(2008/7/10 build) and Tb 2.0.0.14, on MS Win-XP SP3, with Gmail IMAP account(imap.gmail.com). Tb issued "append" command for mail which was copied/moved while "work offline", upon change from "work offline"->"work online". "Mails in local folders" are really new mails for Gmail? Or "mails downloded from Gmail IMAP" are moved/copied back to Gmail IMAP folder? Which Gmail IMAP folder is used? Special folder such as [Gmail]/All Mail, [Gmail]/Trash, [Gmail]/Spam? Or other usual Gmail IMAP folder? If copy/move back, it's due to Gmail IMAP current design/spec. - Only single copy of a mail is held in "[Gmail]/All Mail". - A mail in other folder via Gmail IMAP==A mail labeled as "other folder name". - Gmail checks mail data, and Gmail wont't create new mail data copy, if copy back of a mail, although Gmail IMAP returns OK to append command. So, the appended mail will not be displayed as newly copied mail(new mail data of larger UID) by Gmail IMAP upon re-sync, then the appended mail will disappear from a Gmail IMAP mail folder. Get IMAP protocol log, and check real protocol level flow. (See Bug 402793 Comment #1 for getting log)

Local folders is downloaded e-mail from another account. I am downloading to a self-created tag. It has slashes in it (e.g. Personal/Family/Dad. I will try and reproduce this and get a log.

Interesting. I can see the missing e-mail in the local files if I grep for it. The subject I am looking for is in Profiles/adsfadfa.default/Mail/Local Folders/Inbox and Inbox.msf. However, if I use T'bird's search function it doesn't find them. By the way, I don't have a Local Folders folder in T'bird. I only have ISP names listed at the top level.

I just went offline and back online again and I saw the sync happen. A number of messages were synced in a number of folders. I can see them in the web interface to GMail but I can't see them in Thunderbird. I'll have to keep my on this.

FYI. When local mail folder, "delete/move of a mail" is merely flag as MSG_FLAG_EXPUNGED in X-Mozilla-Staus: header (will never be shown as a living mail in a mail folder). See http://www.eyrich-net.org/mozilla/X-Mozilla-Status.html?en for flags. This is reason why "compact folder" is required for "local mail folder" or "local copy of IMAP folder with offline-use=on".

Since the messages eventually got synched I am going to downgrade the severity from "critical" to "normal". I have also changed the title to better reflect the actual issue with this bug. I will continue to keep my [eye] on it and report back if I get some better information.

stephen, can you confirm problem is gone using current nightlies and beta? backup your profile before using ... http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/latest-trunk/

I can't reproduce this on Thunderbird 2.0.0.19. If I move to a folder it doesn't appear immediately but if I move to a different folder and then back again I can see it.
