Thunderbird Support Forum

After the Thunderbird 91.9.1 update I get errors sending emails. Small emails work. One email that fails is 17.9KB and if I remove some text it will send. The same thing happens on other emails and also other gmail accounts. I can receive emails with no problems.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.

Outgoing settings Server: smtp.gmail.com Port: 587 Connection Security - I have tried both SSL/TSL and STARTTLS Authentication Method - I have tried both OAUTH2 and Normal Password

I can't for the life of me find out how to stop Thunderbird from deleting my emails form Thunderbird and my email server. I use to think it was after 30 days but my oldest email is from May 11th, today is the 26th. So maybe it's a set size limit. My email is through my web hosting provider and it is set to unlimited. When I asked them they said there's a setting on an email client that is deleting my emails. How do I fix this? I have tried to delete the email account and add it again from scratch but that didn't do anything. Many times I need to access older emails from my customers that are just gone.

I know another person mentioned this before but I didn't see a resolved answer, only that he created a new folder to import his old messages to. Which I don't see how to do that but also feel that's just a band-aid type fix. I want my emails to stop being deleted automatically, only if I delete them.

The email composing window includes Write: in the title (before the actual email title). How can I remove this part from the title?

The space I have on my device is narrow where I can see the titles of the emails being composed and I would like to see only the email title in that location, without the "Write:" portion. Does anyone know how I can achieve this?

I have a lot of issues with my mailbox. Constantly have to repair folders because the wrong subject shows on the wrong email. A big one I had was my inbox getting bogged down, but I learned it doesn't like to have more than a couple thousand emails in it. I kept getting a "exceeded maximum number of connections" error but read something about too many folders, got rid of a few folders and that error went away.

1) What other kinds of tips are there for keeping TB behaving well? 2) I see that my profile has a lot of old files for old folders that don't exist anymore. There's also nstmp files and foldercache.json files. Should I delete all these types of things to clean up? Or should I just start fresh with a new profile and re-download all my email messages? I can't imagine how long that will take because sometimes folders download quickly but other times take forever and I'm not sure the difference. I just downloaded a 4000 email folder in a 20th the time of another 2000 email folder.

Hi I have my email on my server with my hosting company for various sites. Nothing has changed on this set up for years and now in the last week I am getting the message "connection to server "my site" has timed out." but only for the two emails associated with this one particular site. I deleted the smtp, deleted the incoming settings, added back, same error. The email is working fine on my other devices and the emails for the other sites are all working fine on thunderbird, too. Thunderbird is up to date. Any ideas?

I'm sure I've always had years of emails in my Bins, but recently noticed 1 Bin only having about 1mth's. They go back years in All Mail. 1 account's Bin has had emails put in during the last month, but is empty. I just tapped on another, an account not used much now, where I've kept seeing emails from a long time ago. On tapping, I could see them all for a split second, then they vanished. I want to keep all my deleted emails in my Bins.

Thunderbird 68 - deliberately not updating. Server Settings > When I delete a msg: Move it to Bin. Storage: neither option ticked (neither checked, if you're American). Synchronisation > Msg Synchronising > Keep in all folders. Advanced > all ticked. Disc Space > Synchronise all regardless of age. Don't delete any.

Gmail > Forwarding & IMAP > IMAP access: Auto-Expunge off. Archive the msg. Do not limit.

Any help greatly appreciated.

After a recent update, Thunderbird now lists other conversations in my message pane. How can I get rid of this list and go back to the default view of just the email that I have clicked on?

I often need to add a single pixel border/line around an inline image (an image just dropped into the body of the email). For many years I have been able to select the image, hit the 'link/anchor/image' button, knock the up arrow on the 'solid border' option and click ok.

Now, when I hit the 'link/anchor/image' button the radio button next to 'Alternate text' is selected. I have to remember to UNselect it every time or I get the intenseley annoying error "If the image is relevant to the content of the document you must supply alternate text, blah blah blah..." then do it all again.

I don't think we should be forced to add alt text, nor unselect the button every time. Surely this alt text button shouldn't be selected - it means that by simply hitting the 'link/anchor/image' button and then OK (without actually soing anything) an error dialogue is provoked! This can't be right, can it?

i have mail in my inbox in thunderbird account that is not in my inbox in my Yahoo account.

I am using Imap

How do I get email from my thunderbird inbox to my yahoo inbox? I am using Imap - but I can get these emails there.

Thunderbird non si apre più, da 5 giorni. Ho notato che il computer ha rallentato moltissimo tutte le attività e, dopo il riavvio perchè bloccato, Thunderbird non si apre più. Non compare neanche la schermata iniziale; ho provato con il tasto shift ed il tasto destro del mouse ad avviarlo come "amministratore", poi ad aprire la rubrica ed ho controllato tutto quanto possibile per le mie (scarse) conoscenze informatiche. La casella mail, sul server, funziona perfettamente; ma senza thunderbird non posso aprire l'archivio "storico", con centinaia di messaggi e continuare sul solo server è estremamente complicato. Ho provato anche a cliccare sull'icona da "start" (win10 a 64 bit), ma è lo stesso, nessuna reazione, nessun caricamento, come se non esistesse. Non so come fare, grazie

I use Thunderbird to download my email from my Gmail account. On 24 May I closed down Thunderbird in the afternoon, later that evening I opened up Thunderbird to check on my emails, Thunderbird indicated it would start after it finished downloading the latest update. I have been unable to access my emails from Gmail since that update. I did receive a message indicating that there might be a problem with the number of server connections to cache. My connections were set to the default 5 connections. I tried resetting to 10 but I still could not download my emails. I also tried setting to 4 but still was unable to download any emails. Just in case the problem was only with downloading emails I tried sending an email but I received the following message: “Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.” I have tried the “Troubleshooting” option under “Help” but nothing is happening. I am running Windows 10 and Thunderbird 91.9.1 (32-bit)

There are corrupt inbox sub-folders on our Rackspace account. Thunderbird will not 'get messages' and throws a 'SERVERBUG' error. Then proceeds to tell me to look at the server logs. Right! Rackspace is going to let me look at their server logs.

Anyway, Rackspace says this is a known Thunderbird bug. The 'SERVERBUG' error message is being generated by Thunderbird and there are no server log error messages.

FWIW Apple iPhone native mail client and Rackspace Apps web client also fail to open the corrupted folders. Only iPhone and Thunderbird generate consistent error messages.

Anybody got an idea what is going on here? I'd really like to check our mail.

Thanks

I have changed absolutely nothing on my computer and this has just happened out of the blue. The following message appears whenever I attempt to send an email:- Sending of the message failed. An error occurred while sending mail. The mail server responded: 626F290E04D8BA88 Message content rejected due to suspected spam. OB703. Please check the message and try again.

Today Thunderbird stopped being able to reach the Yahoo server to access my mail. It tries to search for mail but says that the connection to the Yahoo server timed out. I am able to download and send mail from my Yahoo account if I use their webmail site or phone app but not Thunderbird. Mailbird (which I just downloaded to see if it would work) was also able to download Yahoo mail. I checked the Thunderbird account settings (set for POP which I prefer to keep for various reasons) and they are the same as they've ever been. I'm using Thunderbird version 91.9.0 which worked just fine until today. It does seem to still work when accessing a different email (GMX) account.

Any help would be appreciated. I would like to be able to continue using Thunderbird which has been my mail program of choice for many years.

Hello I try to move emails with the filter function (from x to z). Both folders exist. I can not choose the destination folder. It is dimmed and says "Destination folder not available". Thank you Heinrichxx

I started my Mac Thunderbird 2 days ago and all of my email accounts were blank.

Everything from the Library files were deleted.

Anything to offer? This happened about 5-6 years ago.

I can go into my TimeMachine back-up and redo the entire drive or, hopefully, less than that just all of the Thunderbird stuff in the Library section.

Regardless, how the hell does this happen? This occured after updating to your latest version a day or so earlier.

Great job guys.

I have asked this question before with a different subject title, and I am surprised there is no move to fix it. It is an annoyance that I expect effects many. So I am trying again with a new title and more explanation.

I have attached 3 images, showing a) how I have my folders layed out, b) viewing a group of my folders including my local folders, and c) the change in view after I rename one of the observed folders called "Amick." Instead of the view staying the same, so that I can see the name-changed folder in the folder structure, it reverts to the top of the structure showing all the favorites followed by the local folders.

What I would like to have happen is for there to be NO CHANGE in the view after I change the name of a folder or delete a folder, so that I can see what I have accomplished and continue working. As it is now, it is a big nuisance the time waster. Am I missing something that I can do to solve this problem, like some advanced setting?

Thank you.

Suddenly, Thunderbird stopped delivering emails from one pop 3 gmx.net account (the others are okay, including an IMAP gmx.net account). TB DOES still deliver these emails to my IPhone SE (15.4.1--the current OS). I use TB 91.9.1 on a MacBook Pro OS 10.14.6. I have checked all the settings on TB and GMX. I have deleted a lot of emails and cleaned the cache and compressed folders. I deactivated the firewall. Nothing works. Please help! Nancy

Is there any way to use CSS to style the Thunderbird Print Preview drop-down menus? I tried using the same agent sheet that works in Firefox, but it didn't work in Thunderbird.
