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.

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.

Trouble connecting to my email provider Time Warner Corporation to send emails using my wifi. They claim I have to be connected to Spectrum to send them using my WIFI and they are not in Massachusetts where I am now for the summer. I get the following message when I try to send one using my wifi:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout004.msg.pkvw.co.charter.net cmsmtp 73.238.167.193 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

‘I can login to Orange website & read my mails: Thunderbird, using same password, gets "Authentication Failed", This on 2 accounts.’ for ‘Thunderbird’. This is a recent problem, occuring after a series of"Account blocked , due to suspicious activity"

This past Saturday (21st) I noticed it was taking longer to get emails from Spectrum. I had to click the Get Messages button several times and eventually the box to put in my password would pop up. After putting it in the emails would finally show up. This continued into Sunday, but by late afternoon I was getting no emails from Spectrum. I tried sending a test email from Thunderbird and got the following error message:

An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout007.msg.chrl.nc.charter.net cmsmtp [my IP address] blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1120.

I went to the Spectrum website to look up the error message and found this:

The IP address you’re trying to connect from has an issue with the Domain Name System (DNS). Spectrum requires a full circle DNS for emails to be allowed through. Verify the IP you’re connecting from, and check the IP address to ensure a reverse DNS entry exists for the IP.

At that point I called Spectrum tech support, spent about 2 hours talking to 3 different people, but I got no solution. I was able to verify my IP address is not blocked. I was basically told everything is fine on their end, so I should contact Thunderbird. All of my emails are still on the Spectrum website. I can send and receive on that site. No changes have been made to account settings or my password. I’ve tried to find an answer using Google and Youtube, but nothing so far. I did look on the Thunderbird forum, found a post from someone who was also having trouble with their emails and Spectrum this weekend. I’ve downloaded the latest version of Thunderbird, 153.1. One of the tech people suggested I use the Repair tool in Thunderbird on one of my folders. I wish I hadn’t. I used it on the Inbox folder and all of my emails disappeared in Thunderbird. They’re still on Spectrum’s site. If anyone has an idea for a solution I’d appreciate it.

As I was about to post this I opened Thunderbird and about half of the emails from my In Box have reappeared.

I have had a problem the last few months with my power/sleep settings in Windows being reset to "Never" and it appears to happen when I get Thunderbird updates. Have I done something incorrectly?

My emails suddenly stopped coming in. Everything was working fine until now! When I try to get emails in thunderbird, I get the message that cannot access the server, or that the system has timed out. I am using Thunderbird for my charter email accounts. I am using Windows 10 on my PC. I checked all email settings in Thunderbird and they are correct. I went to the online email with Spectrum/Charter website, and it is all there.

I need help understanding why this suddenly happened. I am using my Outlook email for this forum since I can't receive my charter emails. My outlook email on same PC is working correctly. Any help would be appreciated! Thank youm

I have just used a saved email address to write an email. When I went to send it the send failed because the from account was an old account I do not use anymore.

How do I change saved email addresses so they do not use the old account.

Why would this happen.

I checked which account I was using at the time and then repeated the process with the same result. I was using my current account.

I have been using Thunderbird successfully for sometime and since yesterday there were no new emails in my inbox. This coincided with Thunderbird being upgraded, so I am told. So, I tested by sending an email to myself but TB kept assuming my old email address was valid (died last year) and any attempt to get in and edit my address failed because it kept thinking the old email was was still valid. So, I installed Betterbird, hoping it might work but it copied over my profile, etc and it had the same problem! I guess I could look far another email client but I want to stay with Thunderbird.

Any suggestions please. Robin

“My Spectrum email address is [redacted]@charter.net. Spectrum webmail can send and Thunderbird can't receive or send. The outgoing server is mobile.charter.net and the connection times out. I tested the connection from my computer and ports 587 and 465 both respond successfully. Thunderbird is set to No Proxy. when i tried to send today, it gave me this message, "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mobile.charter.net timed out. Try again." i contacted spectrum about this and now when i try to send, it says nothing and the message never arrives.

Bonjour,

Depuis le passage à Thunderbird 154.0 (64 bits), plusieurs de mes comptes IMAP ont vu leur arborescence se modifier de façon inattendue.

Avant, j’avais une présentation de ce type :

Brouillons Envoyés Archives Indésirables Corbeille Courrier entrant Clients Fournisseurs etc.

Depuis peu, sur plusieurs comptes, les dossiers spéciaux Brouillons, Envoyés, Archives, Indésirables, Corbeille apparaissent désormais sous Courrier entrant.

Le phénomène touche notamment :

un compte Orange ; un compte hébergé sur un domaine personnel ; un autre compte professionnel IMAP.

En revanche, un compte Free reste affiché correctement.

En comparant les abonnements IMAP, je constate que :

sur le compte Free, Sent, Trash, etc. sont réellement à la racine du serveur, tandis que les dossiers personnels sont sous INBOX ; sur les comptes qui posent problème, les dossiers spéciaux et les dossiers personnels sont tous sous INBOX.

J’ai essayé le paramètre :

Paramètres serveur > Avancés > Dossier sur le serveur IMAP = INBOX

Cela fait bien remonter les dossiers spéciaux au niveau du compte, mais cela remonte également tous les dossiers personnels, donc l’arborescence devient entièrement plate.

J’ai également constaté qu’un déplacement manuel peut produire une erreur du serveur du type :

Client tried to access nonexistent namespace. Mailbox name should probably be prefixed with: INBOX.

Je cherche donc à savoir :

Thunderbird 154 a-t-il modifié la façon dont les dossiers spéciaux IMAP (Sent, Drafts, Trash, etc.) sont affichés lorsqu’ils sont physiquement sous INBOX ? Existe-t-il un réglage permettant de conserver les dossiers personnels sous Courrier entrant, tout en affichant les dossiers spéciaux au niveau du compte comme auparavant ? S’agit-il d’un comportement connu ou d’un bug de la version 154 ?

Je peux fournir les paramètres IMAP avancés et les captures des fenêtres S’abonner si nécessaire.

Merci.
