I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

New incoming emails are no longer marked as "unread" and In bold print when they arrive. I have to manually mark them as unread. Then when I read them, they do not consistently change to "read". This was not a problem until I started using the 128.10.0esr (64-bit) version of Thunderbird.

I recently had to do a clean install of Windows 11. I followed the instructions on how to save Thunderbird info to be entered back into Thunderbird once I was up and running again. Well I'm up and running and am trying to install Thunderbird. Thunderbird sees me from before I did the install of Windows 11 and is setting me up without me doing anything, until it came to password time....... I do save my passwords but cannot find one for Thunderbird. I do have on for Firefox. I tried creating a new password but Thunderbird isn't accepting it. I don't see any "if you forgot your password" choices that you normally see. How do I either change my password or get hints on what the old one is?? I might need help on installing the info I saved before the Windows install.

I am trying to upgrade from 128 esr version to the new 139 version. I tried several ways to transfer data from the old version to the new version - I tried to export and import a the Thunderbird zip file. I also tried to open profile manager and creating a new profile that refers to a copy from my old version. Nothing has worked. In the old Thunderbird 128 version, if I select Help and Troubleshooting Information and then Open Folder next to the Profile Folder I get an error in Thunderbird that it can’t find my profile. I get the same error message when I go to Tools, export and select "open profile folder." This in spite of the fact that the old version continues to correctly display my contacts, tasks and events

After several hours of this, I finally decided to download version 139 using the standard Mozilla set up even though my Thunderbird 128 version is located someplace else. So, at this time I have two working versions of thunderbird on my computer – the old 128 version with all my data and the new 139 version with no data.

I think I need help figuring out which Profile has my contact, calendar and task data. Then I need help getting it to the new version.

Thanks

I set up a CardDAV addressbook link to my iCloud addressbook. Everything is fine, and syncing works great. After ~2 days, it stops working and I have to generate a new app-specific password, delete my addressbook, and re-establish a new link with the new app-specific password. I tried to turn on CardDAV login, but nothing it written to the logs.

Has anyone run into this problem and how do I go about troubleshooting it?

Hello, I am using Kubuntu 24.04.2 LTS on a Lenovo T470. After a regular installation of updates via Discover three days ago, thunderbird can no longer be started via the icon in the window bar (message: KDE -Plasma workspace: The file or folder /snap/thunderbird/644/usr/lib/thunderbird/thunderbird-bin does not exist).

I was able to start thunderbird via the menu (the location now appears to be /snap/bin/thunderbird), but the profile and all mails have disappeared, as if I had reinstalled thunderbird.

The Personal folder/snap/thunderbird folder contains the folders 721, 734, common and current. Only common has something, but very little content (25 MB).

I set up my profile again in the post-update thunderbird (no problem thanks to imap-server), which works well. However, now I have two icons: If I click icon no 1, thunderbird starts as a new installation without any profile and mails, icon 2, thunderbird starts with my profile.

Can anyone make sense of this strange behavior?
