For a few weeks now we have been unable to send emails through tbaytel server via Thunderbird. We get SMTP error. This happened after recent upgrades to Mozilla. Any idea when a fix will be out?

Tried adding my outlook account, it said that the account settings are found automatically so when I left those options unedited and clicked continue it showed this error. Have no idea what went wrong though.

Kan ikke modtage og sende mails. Får følgende besked - Kunne ikke skrive mailen i mailmappen. Sørg for at du har skriverettigheder til filsystemet, og at du har nok diskplads til at kopiere mailmappen.

Hello !

I'm using Thunderbird in the dark mode. When I open the detail of an event in the agenda, the text is still written in black, on a gray background so this is not really readable (cf linked screen shot)

At some points I had similar issue with mails, but I found the little button "toogle dark mode for mail" that allow to keep the dark mode for thuderbird but show the mail with white background and black text.

Is there a similar functionality for the agenda ?

Thanks !

Short problem description: Gmail auth is running before the master password dialogue

Long description: When starting up, Thunderbird runs Gmail auth before the master password dialogue. This leads to a failure of the login when the user does not enter the password in time. The access token is not unlocked, auth fails, and a browser window will pop up with the gmail authentication dialogue, necessitating further user interaction and generating extra mails because TB will be reconnected with a regenerated token.

Expected behaviour: Authenticating email accounts being delayed, until the secret cache is unlocked with the master password.

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

I'm trying to add an email account to Thunderbird that (seems to) require Oauth2 authentication, but it keeps opening the wrong provider in the Firefox window that it launches. The email account is a professional G-Suite address, but it always opens login.microsoft.com instead.

I've checked the MX record for the domain and it correctly lists Google servers, and my laptop was able to authenticate to the correct destination just fine. I have used my desktop for work before, which is all handled through Microsoft accounts, so I suspect that there's some kind of locally cached data which is identifying O365 as the provider, but I can't find any relevant settings or documentation from Firefox. I also cannot find any settings or controls for the Oauth provider in Thunderbird in order to force a Google workflow.

I have two different email accounts in Thunderbird. For the last few days, my Yahoo mail will not download. I can go to Yahoo, but prefer not to. My other account will download. I have just noticed that it seems to be downloading the same eight or nine emails over and over.

Thunderbird in Linux has worked perfectly for me for many year. This is my first ever problem with emails not downloading through Thunderbird.

What could be the problem?

I like the new support for Outlook. Thank you very much. This was the first year that I did not spend >16 hours rebuilding accounts each January. It is also nice that this support automatically transfered incoming emails to the Local Inbox.

Just recently, Spectrum Internet dropped POP3 support and I was able to setup IMAP.

Gee, It would be nice if there was just one more checkbox in the Account Setup which would automatically transfer IMAP messages to the Local Inbox.

Can this be added to the wish list?

Hi, I am running a windows 10 with Thunderbird version 157.0.1 (64bit) IMAP version. I am having problems with quite a few of my old messages not wanting to open when I click on them. This is the message that pops up (Server mail.daystar.io has disconnected. The server may have gone down or there may be a network problem.) mail.daystar.io is my carrier.

I'm running the current 157.0.1 release on Windows 11, and specifically am having my emails from the AP be sent to spam even though I have a specific filter set to tag them. I feel as if the filter itself is set up properly because when I manually run it the messages will be moved from the spam folder to the inbox and tagged accordingly.

The one thing sticking out to me is these emails are being forwarded through my relay account. I've tried changing the filter to work based on the relay address, but again it only works when I manually run it. I've also tried setting the filter to run both before "and" after spam classification, but neither option works. Ideally the filter would work without me having to go to my spam and run it, and even then I'm wondering why the spam filter hasn't learned by now that those email belong in my inbox.

I'd appreciate any help or solutions; I'm not an email power user or networking wiz though so please try to keep it as dumbed down for me as possible!

Today TB froze during start up. No problems yesterday.

I deleted global-messages-db.sqlite and restarted TB. Now it is frozen with a "Loading messages". Maybe it is rebuilding indexes and this takes a long time and I should be patient.

Maybe my In and Sent mail boxes are too big? If so, how can I safely prune them?

TB is becoming increasingly unstable for me. It was very reliable before about a month ago.

I doubt my AV is the culprit because AV has not changed today.

Thank you one and all.

I get "connection to server pop.mail.yahoo.com timed out" every few minutes. mail is not usually delivered, and some mail that's delivered is from two-three weeks ago that I've already gotten. It seems that I've stopped receiving mail for account "redacted@frontier.com" after 10/8/26. Mail that's sent to other accounts seem to be delivered OK, but mail that's sent to this account doesn't show up. I've received at least some mail for account "redacted@frontier.com" for 10/9 and 10/10. Not sure if I'm getting everything. Mail seems to be received at the yahoo.com website for both email addresses [redacted@frontier.com and redacted@frontier.com]. At least I hope it is! Mail also seems to be received using the yahoo app for Android [phone] and yahoo app for iPad.

Hello, I am having an issue that Emails which are displayed in the reading area disapper for appr. 2 minutes. Afterwards they appear again. I have not been able to find out if this is a problem in Thunderbird, or if another application is causing this. I have read an article that Avast Antivirus is temporarily locking folders during scan. Maybe someone has had the same topic and can give me a hint where to search for the root cause. Thank you.

I tried to add my Outlook account to Thunderbird, I entered my details and clicked Continue but it stuck in the "Looking up configuration" screen. I then tried doing manual configuration and entered outlook's IMAP and SMTP server but there's an error message that said "Failed logging in to server" and when I try again it became "Incoming server already exists." An OAuth2 popup appears only after I closed Thunderbird and since Thunderbird is already closed the address it's trying to return to (127.0.0.1:41003) is no longer monitored.

My @googlemail.com account has been working in Thunderbird for years. Two days ago it stopped. No incoming e-mails and attempts to send e-mails from Thunderbird result in the outgoing server timing out. I can access direct at gmail.

Please note that my previous e-mail: alan.rhodes@talktalk.net is no longer available The replacement: alan-rhodes@outlook.com has been blocked by MS-AI (It didn't like a circulation e-mail to 60 members of my local history group) The only working e-mail I have is the current problem one: rhodes.alan1@googlemail.com

I moved some emails to a folder and they are not there. Tried to move last email to folder and it jumps back to my inbox. Also how do I access help in thunderbird?
