Please help! I am trying to add an outlook.com account. Mac (Sequoia) -Firefox (132.0.2) -Thunderbird (nebula) The login page flashes briefly, but then I get I get the dreaded:

"Microsoft (logo). We can't sign you in

Your browser is currently set to block cookies. You need to allow cookies to use this service." https://login.live.com/cookiesDisabled.srf?

No matter what I do in Firefox-Setting-Privacy nothing helps! I've tried changing my default browser to Safari and that doesn't help either.

Please help!

I recently changed my password to a passphrase. Thunderbird 115.16 ER Linux could not/would not handle it. By changing to a password based on the passphrase, Thunderbird sometimes works fine.

I had to change my Microsoft password and I believe it didn't change for my TB email account. I no longer know the old password (I use Keeper to make pw changes). I get a pop3 account password error and no longer can get email in TB. I am currently unhappily using Outlook. I made changes on my pc to meet the new requirements mandated by Microsoft: incoming server - pop3.live.com:995; SSL/TLS; 0Auth2 and outgoing server - smtp.office365.com:587; STARTTLS; 0Auth2. Appreciate some help. Thanks

Hello I have a problem where I get an error message "Unable to use profile when you launch an older version of Thunde...."

I noticed that I had 2 versions of the program installed, 115.16.0 and 128.3.3. Thunderbird must have been running okay up to v115.16.0 as I had to do manual installs from then to now. Initially there seemingly was no indication of any problem. I'm not sure how many manual installs I did as it was only 15th Oct that this issue started. I was on holidays for 6 weeks Thunderbird was unused between about 28th Aug to 15th October. So, my Thunderbird was running at 115.16.0. I tried to uninstall 115.15.0 but it said I had another version that needed to have the uninstall completed by rebooting the PC. I did that but 115.16.0 still remained. I uninstalled 128.3.3 successfully. 115.16 still wouldn't uninstall, so I used a program to cleanup all of this version. I reinstalled 128.3.3 and still get the same problem I started with. "Unable to use profile when you launch an older version of Thunde...."

How can I get Thunderbird running? Regards Alllan

I have successfully used Thunderbird for 7-8 years for my business e-mail account. About 2 weeks ago the platform simply wouldn't send or receive any more and I have no idea why. I would like some help to get this working once again

after latest update nov 12 128.4.3esr 32 bit my wife can not access our same email server mail.patokalakemarina.com. Gets security alert of invalid certificate. When I try to add an exception says is good and don't need an exception.

My 64 bit machine took the upgrade ok, no alert, and her android phone still accesses. Every box is checked the same as my 64bit. How to roll back an update?

Whenever I click away from the write window while writing a reply, the window gets closed, not minimized, and the email is sometimes saved as a draft. I'm not sure how to fix this, I'm using Thunderbird 128.4.3esr for Arch Linux.

Thunderbird gobbles up too much of my SSD space!

How can I prevent this from happening?

I'm using Thunderbird 128.2.3esr (64-bit) Safari browser Version 18.0 (19619.1.26.111.10, 19619) Macbook Air M2 15" running OS 14.7

Good morning. I am using Thunderbird version 115.16.2 (32 bit).

Several days ago when every I attempted to get email by clicking on the "Get messages" button on my menu bar, nothing happened. If I went through the menu (File -> Get messages for -> email address, I would receive a box message titled "Add Security Exception". I have added a screen shot image.

If i clicked "Confirm Security Exception" I could then receive mail the way I normally do by clicking on the "Get Messages" button on the menu bar.

But the next day after booting my computer, I would need to repeat this once again.

This is not normal. Is it an issue with Thunderbird or should I take this up with my server provider.

Thanks Pete

I have a problem with receiving POP3 and sending SMTP emails, but it only concerns the Onet (onet.pl and onet.eu) server. All POP3 and SMTP settings are correct, verified. The problem appeared a few days ago, probably after an update. The problem with receiving is when I receive emails in bulk from all accounts by clicking the Download button (Download new messages for all accounts). They are downloaded from all servers, except Onet. This problem does not occur if I download messages from Onet by clicking in the menu File/Download messages from/account name. The problem with sending messages appears when after writing an email I click the Send button (Send this message). There is no problem if I click the File menu/Send later, and then in the Outgoing folder I click Send pending messages. Can anyone help me to solve this problem?

I am sending emails but they dont appear in the Sent folder. I have changed no settings. They used to go to the Sent folder but have stopped. All my settings are correct but the Sent folder is not being populated. Whats wrong?

Hello, Since the Oauth2 security from Microsoft, I can't send messages anymore from thunderbird with an outlook adress (but I can receive messages after following instructions) I followed rigourously the instructions from Microsoft and Thunderbird on this two pages : https://support.microsoft.com/fr-fr/office/param%C3%A8tres-pop-imap-et-smtp-pour-outlook-com-d088b986-291d-42b8-9564-9c414e2aa040 https://support.mozilla.org/fr/kb/microsoft-oauth-authentification-thunderbird (These are pages in french because I'm French hence my poor english (sorry for that)) And tried every solution (for instance, the smtp server advised is not the same for Microsoft and Thunderbird, of course I tried both many times)

Thanks for your answers Michel

Thunderbird for Mac won't allow me to set up Gmail. I'm using the latest version (128.4.3esr) of Thunderbird on Mac OS Sonoma 14.6.1.

It gets stuck on "Checking Password"

I've gone through all the standard checks - The password is correct, IMAP Access in verified in Gmail, Accept Cookies is on in Thunderbird settings, incoming and outgoing server details are correct. Firewall and anti-virus are off etc.

I really want to stop using MS Outlook for Mac, but need a reliable Email client. Am hoping this is Thunderbird....

Anyone know a fix for this? Thanks

I have three e-mail accounts. By some mysteripous reason TB sets the first one as default. Trying to change is no avail. Even though I select the correct standard account in settings TB refuses to make the change. Would appreciate some advice. /Leif Arvidsson

I have Thunderbird 128.4.2 (32 bit) on Windows 10 Home (64 bit). I want to add a second email account. To do this, I used File> New> Email Account. I entered the email address and password. TB found and entered a server configuration. The new email address appears in the Folder List but has only an Inbox folder after it. The other folders (Sent, Junk, Trash) are missing. Test messages show the new address in TB will send a message correctly except it hangs trying to save the sent message. The new address is unable to receive a message. Please advise how to get the new email account (outlook.com) set up in Thunderbird. Thank you.

The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.

Yesterday I was unable to receive or send e:mails. Thought they fixed it, waited until morning to check in.

My e:mail ([edited] @gmail.com) was just fine on my lap top, but when I looked on my desktop, it was just the same. Can't send or receive e:mails there.

What's the problem now?
