I have made 3 attempts to add a thunderbird account to receive email from an old verizon.net account server. All have failed.

All three times, I got the message.

     "Unable to login at server. Probably wrong configuration"

which is a remarkably ambiguous error message. It takes about 10 minutes for that message to appear.

I am able to log directly/independently into what I understand is the verizon server. But obviously I am doing something wrong.

Independently, I successfully added a thunderbird account for an outlook.com.

I will skip the verizon account for the time being. I have one other account to move the Thunderbird.

I successfully moved all three to Mac mail a few weeks ago, only to discover that I really don't like it for a variety of reasons, the most significant for me was that

     - I learned about IMAP
     -  I couldn't delete messages, although IMAP on a mac creates the 

illusion that I could.

There is nothing quite like seeing messages that I know have deleted, reappear marked as unread, right before my eyes.

Thoughts anyone?

I logged in to Thunderbird the other day and none of my stored folders were displayed. I logged in to my Virgin Media Email and they were all there. About 9 months ago I had a similar problem and it was resolved using my Thunderbird backup and help from yourselves. I cannot get this to work this time. Firstly I would be keen to know why the stored folders have suddenly not loaded when I start Thunderbird. Secondly is there an easy way to get the folders downloaded from Virgin Media rather than trying to use my backup? Thanks.

I am using Thunderbird version 128.7.0esr on Windows 11 Pro. I moved my Mail folder (and sub-folders) on my local drive. I re-directed each of 4 email accounts to their new sub-folder. The emails are downloading from the email host's POP3 server. New email messages are not visible in any of the inboxes. The counter shows the number increasing when messages are downloading. Global search does not find the new emails. The new emails show when I right click on any of the inboxes and select "Search Messages" (From/Contains."@"). I tried manually removing the Inbox.msf from one account, but did not fix when I restarted. I tried the Repair Folder button (right click Properties on Inbox folder), but did not fix. I know the emails are on my computer, but I cannot get to them without the very cumbersome "search messages" function. Suggestions?

Been using thunderbird for years, stopped getting new messages. Removed/deleted the accounts and tried to setup again and get error unable to login at server, probably wrong configuration, username or password. username and password are entered correctly, changed them just to verify, using default settings and appear to match what their supposed to be as documented. Gmail accounts... Any help appreciated...

Starting this week, an increasing percentage of, BUT NOT ALL, incoming e-mails are coming through unformatted, which makes them almost unreadable. In the Cards pane nothing appears except the time stamp. Some examples: id CD/0A-06843-A1BCB986; Tue, 12 Aug 2025 23:15:38 id 09/00-49518-8A0AC986; Wed, 13 Aug 2025 10:26:48 id 24/87-15587-133DD986; Thu, 14 Aug 2025 08:14:41 id 05/94-10997-4184E986; Thu, 14 Aug 2025 16:33:24 I'm running ver. 140.1.1esr (64-bit).

The same messages appear fine in Thunderbird for Android on my phone. Anybody have any clue as to what's going on?

Why does it take 30 minutes or more before Thunderbird downloads the new messages for the day. Most of the time Thunderbird will not download new message for 30 minutes or more. And some times it will let me know i have new messages and not download them Pleas help. I must have missed some indicator

I know that there are thousands of threads related to moving a profile, but despite having read many of them I am still struggling to move my profile (and I have been trying to do this for several years)

the Default profile is setting up under my Home directory that that is burning up about 10GB of space.

Folliwing Moderator Matt's excellent suggestions:

"so when you go to the troubleshooting information and select profile folder, where does it put you? In a different newly created profile folder. So copy everything to the new folder from the old one"

I DO finally seem to get all my old TB accounts and messages to show up from the moved location.

However, I can neither send nor receive email. which suggests that my Gmail IMAP and SMTP settings are wrong.

My IMAP settings are showing as: Port 993 Security: SSL/TLS Authentication: OAuth2

my SMTP settings are Port 465 Security: SSL/TLS Authentication: OAuth2

When I close the Newly moved profile and restart and specify the original profile (that is housed under /Home) the server settings there seem to be the same. But I am able to send and receive email under that profile.

what am I doing wrong?

Hello, I speak french therefore sorry for my english ! I have since 3 days, the impossibility to send a mail. I always receive an error message like this :

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail : erreur du serveur SMTP. Le serveur a répondu : bluewin.ch mailout-004.p.bluenet.ch Swisscom AG sc774: Blocklisting in effect.

This have been caused as I wanted to send a message to a list of more of 100 personn and the system of my provider (Swisscom Bluewin) blocked me.

I contacted them explained the situation and the have deleted the blocking list and if I go on the email of the provider Swisscom I am free to send message without problem.

BUT in Mozilla Thunderbird i am still blocked with the above mentioned error message !

I have controlled all my SMTP info and they are correct, I have try to disabled the Bitdefender security but no way it remains blocked.

My question is, is this blocking list only remaining in Mozilla Thunderbird and for how long time or someone can help me to cancel this blocking list in Mozilla Thunderbird ?

Many thanks in advance for your help

Folders are visible in webmail but not updating in Thunderbird. Server settings have been checked and are correct. ALSO .html signatures are not updating or saving to account. When Thunderbird is closed, the attached signature disappears

Running Thunderbird with three accounts on my desktop PC - two 'btinternet.com' accounts and one 'gmail.com' account. Inboxes have no more than 20 emails in them, as I delete unwanted ones and transfer others to various sub-folders ( In excess of 40 No.). Today I suddenly found that incoming emails on both bt accounts were not showing the subject or sender and the content is displayed in plain text (txt) format - no problem with the gmail account.

I have compacted and repaired the inbox folders but no difference. If I send a message from either of the bt accounts to the other the problem occurs, but if I send a message from either of the bt accounts to my gmail account, it goes through fine. I can receive bt emails fine on my laptop. I assume this is a thunderbird problem on my PC but not sure where to start - would be really grateful for any guidance.

One of my email addresses, which I haven´t used for a month or so, has stopped sending messages. I am told to check my SMTP settings. Incoming messages are being received. The server is smtp.office365.com I am using port 587, as recommended by the Outlook site. I was using 465. I have restarted the pc since making the change. The email address is ....@outlook.com Settings are: SSL/TLS OAuth2

I am using WIndows11

I cant find any useful advice on the Outlook site.

Any suggestions ?

My email from a third party domain is routed to both my gmail inbox and to my thunderbird client. The emails typically get received by thunderbird first, and I read them quickly because of the notification that comes up. However, these emails on thunderbird disappear as soon as they show up in my gmail inbox. Does anyone know how to prevent this? I haven't found any other similar issues on the support forums or other sources.

I have had Thunderbird for decades and have donated a small amount twice to its maintenance. Now as a result of a password change and perhaps some setting change I was not aware of and then a uninstall and reinstall of Thunderbird 4 times, I have lost my archived e-mails (did not realize a profile had to separately be set up for archived folders) and lost about 1/2 of my old e-mails as well as all my sent e-mails. Now I CANNOT SEND OUT EMAILS through my desktop but can do so through my phone - thus nothing wrong with the provider Spectrum. So something has happened on my desktop to prevent sending out e-mails even though I can receive incoming e-mails. Thus nothing wrong with the password. Also, I temporarly shut down anitvirus and firewall but that did not remedy the situation. I spoke to spectrum technical support and nothing from their end. Also, I have the current ports and settings. I love the way Thunderbird looks and its utilities compared to Gmail and Outlook so hate to walk away from it at this point. I posted before and want to see if anyone else has a simple solution. Would appreciate any considered help. please.

I am running Thunderbird 115.18.0 (64-bit) on Linux Mint 21.3 Virginia (base: Ubuntu 22.04 jammy). My goal is to create an offline copy of a 13 GB gmail account in local folders and then delete all the custom IMAP folders to regain some free space in gmail storage.

I am achieving this by: 1) Setting up an IMAP account in Thunderbird for the gmail account. 2) Enabling local storage of all folders (in Settings and set config flag, etc). Changed gmail settings to unlimit the number of IMAP downloads. Set Thunderbird account concurrent connections to 15 (gmail max). a) Edit/Preferences/Advanced/General/Config Editor: mail.server.default.check_all_folders_for_new = true 3) Click on each IMAP folder in Thunderbird to initiate download of that folder. I don't see this documented anywhere but it doesn't seem to download the messages in each folder until I do this. 4) Turn Thunderbird offline and ask it to download all emails before going offline. 5) Copy all folders from the gmail account in thunderbird to local storage. 6) Turn Thunderbird back online. 6) Delete custom IMAP folders in Thunderbird gmail account to clean up gmail online storage.

In my mind, step 2 should be enough to force a download of all emails in all IMAP folders. I added steps 3 and 4 because it's unclear when this process is complete. Especially given gmail IMAP bandwidth limits: https://support.google.com/a/answer/1071518?hl=en

My questions relates to step 3 and 4. In step 3, I don't really have any way to know when Thunderbird has finished downloading all emails from all the gmail IMAP folders. I'm experiencing the typical gmail login issues and throttling due to too many concurrent connections and given this it could take days if Thunderbird can even keep track of which messages downloaded and which got errors back from gmail.

How do I know when Thunderbird has finished downloading messages prior to going offline? Does it notify me with a dialog or do I just have to keep hovering over the Offline toggle periodically until it actually says offline?

Any constructive tips on how to confirm everything is downloaded or process improvements, etc.

Thanks, pi

Every time I open up Thunderbird email I get a message box which pops up saying " Sending of the Message failed An error occurred when sending mail. Were sorry but we cant send your email. etc, etc and "Please check by sending it again(6-1-1-2)

ID (68CA1CA0089AF165) please check the message and try again"

How do I find this message ? When I look at sent items in my mail , I have sent nothing and I am not aware of sending anything.

If this is possible, how do I create filters for incoming emails from specific writers and/or subjects to go directly to specific folder/sub-folders? (I'm looking through the info here, but haven't come across this.)

I have just upgraded my computer from Windows 10 to Windows 11. Due to hardware complications (e.g., new motherboard) I had this done at a shop. I took the computer in about noon on Wednesday, July 30. The upgrade to W-11 finally happened on Monday afternoon, August 11. During that period I received 83 emails to my Gmail account, which of course were not downloaded to Thunderbird, and also sent 13 -- all directly to/from the web Gmail site. Since the activation of W-11 I have received 19 emails and sent 6 -- still all directly from the web Gmail site. Due to additional hardware issues, my computer did not come home until this (Thursday, August 14) afternoon. After I got it hooked up, and running, I brought up Thunderbird. It has downloaded the 83 received + 13 sent, from 7/30 through 8/11, but not done anything with the 19 received + 6 sent emails since then. When I turned Thunderbird off and back on -- or the entire computer off and back on, it has repeated this behavior. Currently I have 332 (83*4) received messages sitting in my inbox, and 52 (13*4) sent messages sitting in my sent box.

What do I need to do, to stop it from repeating this 7/30-8/11 download; and more importantly /start/ downloading messages since then? I feel fairly confident that the timing of the switchover from W-10 to W-11 is not coincidental; and that there is something I need to do in Thunderbird under W-11, to correct this behavior.

All advice will be greatly appreciated.

Thank you, Franklin Coleman
