Hello! I don't understand what's happening with the folders... I've been using Mozilla Thunderbird with this setup for a long time. I had a RedMine folder and a filter configured to move messages from the Inbox to it. But recently, the filter stopped working because it couldn't find the folder on the server, even though I could see it in the folder tree and in the web version of Mail. I deleted the folder and created it again. I enabled the filter, and the messages moved, but they weren't moved to the new folder, but to the one in the Trash, and the new one remained empty. Yes, I restarted Thunderbird, and messages started moving to the new folder, but I don't understand why this happened in the first place—why did I have to delete and recreate the folder?

I tested out the incoming and outgoing security server and they both are successful at SSL/TLS but I still cannot send email. Is there anything else I should check?
i get this message from Thunderbird "could not connect to server, the connection was refused".
I tried what you suggested and did not have any luck so what else should I try?

I recently (unwisely) refreshed my Windows 10. I had to relaod Thunderbird, but when I tried to reinstal my previous profile, I couldn't do so. I've tried using profile manager. but it only seems to recognise two of the six or so profiles that exist in my profile folder. This means I can't access several years' worth of emails - I need to access these for invoice and work purposes. What is really frustrating is that I can see the profile I need in the profile folder, and all the emails seem to in the Mail/popmail/Inbox folder (all with a much smaller MSF. file of the same name). I've tried importing the profile into Thunderbird, but that doesn't work, it just imports the mailbox with no subfolders. A responder called David has already kindly provided advice (many thanks, David), but unfortunately the solutions haven't worked. Can anybody help?
Please give me a telephone number I can call for tech support to talk me through a solution to the problem

In the last month or 2, when I delete an email it does not show in the trash folder. I can wait from 5 minutes to even the next time I reboot my puter to finally see it it trash. Sometimes it sends it to the all mail or important folder instead of trash. And if I delete from there, it still takes tons of time to end up in the trash folder...if it even gets there. This seems to be getting worse by the day. I have clicked repair folder, no change, I have cleared Thunderbird's cache, no change. It's also now taking way too much time to load an email that contains a picture. This happens with at least 3 of these gmails. I'm at a loss here and extremely frustrated and about to change these gmails from imap to pop. win10 and TB is up to date. But it doesn't compact folders as much as it used to either. Any help appreciated

We are facing a critical printing issue with Thunderbird 154.0 (64-bit).
Emails are not printing from Thunderbird and are coming out as completely blank pages. However, the same email/file prints perfectly when saved to a folder and printed from there. This confirms that the printer is working properly and the issue is specifically with Thunderbird.
The problem is affecting multiple systems in our office as well as our Ahmedabad branch, which is seriously impacting our daily work.
This issue requires immediate attention. Please investigate and provide a solution/workaround at the earliest.

This post is more for posterity than asking for a solution because all similar topics ended up being Avast antivirus interfering or something less nefarious. In my case eM client started having this problem first, then I switched to TB, but the same issue here. Of all places, the best clue was found on [[Linux mint|https://forums.linuxmint.com/viewtopic.php?t=213352]] forums. It was a permission problem. Right click on C:\Program Files\Mozilla Thunderbird -> properties -> security. I did two things and not sure which one did it, but they pretty much achieve the same. The Users group in the list only had read permissions so I gave it full access to the folder and checked the option to set the same permission changes to all subfolders. I also added my own personal user to that list and gave that full permissions. Oh yeah, also changed owner to myself from whatever default windows group was there before. Now, do I know the full repercussions of doing this? No. Pretty sure this just created a security hole inside my C drive, but... I don't really care at this point. If I had to fix this again, a solution might be to instruct TB to store the the email files somewhere else rather than where it is installed itself (somewhere less locked down than Program Files).

A couple of days ago we could no longer send or receive email through Thunderbird. When we try, we get the notification "Connection to server mobile.charter.net to [email address] failed" and repeatedly get the notification that our server connection has timed out. We can send/receive through Charter's webmail site, but not through our Thunderbird email client. Thank you for your help.
Why does thunderbird go into "not respondong" so often? and what can I do about it?

THUNDERBIRD 154 - IMAP MESSAGE LIST EMPTY AGAINST MERAK MAIL SERVER 8.5.0
SUMMARY Account sets up successfully. Folder tree enumerates. Message counts and unread counts are correct (folders render bold for unread). No messages are ever displayed in the message list pane, in any folder, regardless of size.
ENVIRONMENT
Client : Thunderbird 154.0, Windows 10 Enterprise 22H2 (19045) Server : Merak Mail Server 8.5.0 (2006), IMAP 143 STARTTLS Auth : CRAM-MD5
SERVER CAPABILITY STRING
IMAP4rev1 AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=LOGIN AUTH=PLAIN SORT THREAD=ORDEREDSUBJECT UIDPLUS QUOTA ACL NAMESPACE CHILDREN IDLE UNSELECT STARTTLS
Note: no CONDSTORE, LIST-EXTENDED, ESEARCH, MOVE, LITERAL+, SPECIAL-USE.
REPRODUCTION
1. Add IMAP account (autoconfig finds 143/STARTTLS correctly). 2. Wait for folder discovery to complete. 3. Click any folder. Message list pane is empty.
OBSERVED
- Empty on every folder, including a 7-message folder and a 19-message folder, so this is not a volume or indexing-time issue. - Reproducible on a brand new profile with only this account configured. - All folders confirmed subscribed via Subscribe dialog. - Error Console (Ctrl+Shift+J) shows nothing when a folder is clicked. - "Run search on server" + Search returns nothing, AND no SEARCH command ever reaches the server (confirmed in server log). The request is never put on the wire. - Setting mailnews.imap.jsmodule=false has no effect.
CONTROL - SERVER IS HEALTHY
The exact command Thunderbird issues works correctly from curl on the same machine, same credentials, same account:
curl.exe -v -u stem --url "imap://<server>/INBOX" \
--request "UID FETCH 1:* (FLAGS)"
Returns all 2932 messages with UIDs and flags. SELECT INBOX reports: * 2932 EXISTS * OK [UIDVALIDITY 1435733459] * OK [UIDNEXT 45598]
Bounded FETCH (FETCH 1:5 (FLAGS)) also returns correctly.
CONTROL - CLIENT IS OTHERWISE HEALTHY
CardDAV and CalDAV from the same Thunderbird install to a Nextcloud server work correctly - address book and calendars sync fine. Outlook (with the same mailbox) reads this server without issue.
LOGGING NOTE
MOZ_LOG=IMAP:5 produces no log file at all in 154 (tried via batch file, as administrator, with Thunderbird fully exited, log path outside any redirected folder). The MozillaWiki instructions for IMAP logging appear to be out of date.
SERVER-SIDE LOG
Below: sessions for user "stem" only. Other users on this server have been removed, all SASL credential blobs redacted, duplicate sessions dropped, sorted by time.
IMAP server-side log - sessions for user "stem" only Server: Merak Mail Server 8.5.0 (2006) Other users and all SASL credential blobs removed.
