I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

Is Mozilla working on the below email I have received from Microsoft? "The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Hi.

Why every time i run thunderbird and if i leave it open too often it bring me the error message for all hotmail/outlook mail accounts i have???

What the heck is happening and how i can solve this?

'bold text'bold textOn 6/24, Juno Security <security@support.juno.com> sent me an email that Thunderbird downloaded that my account had been compromised, & I needed to reset my password. I chanced my password in Juno & put that same password into Thunderbird [I think] Since then I have needed to use that new password to open the Thunderbird program, but Thunderbird won't download email from my Juno popmail to Thunderbird. Thanks for your help.

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

Hi, I'm using Thunderbird 115.4.1 and Windows 8.1 Pro. Ever since the Supernova update, TB crashes pretty much daily (up to 3x a day). I turned off auto-updates as soon as I found out how to, since everything was so confusing and didn't work the way I was used to. Now I'm afraid to do any more updates since I don't want a whole bunch of other things to get screwed up. I have learned to kind of work around the problem areas, though it's frustrating. But I don't want to spend another 10-15 hours trying to fix new problems. Any suggestions? I can't seem to find any information about people who have had this crashing problem and then had it resolved through an update. Thanks

Hi, I have a disaster situation. I backed up my profile and then I wiped my computer running Ubuntu 20.04. I replaced it with Ubuntu 24.04. Now my profile seems to not be compatible with the Firefox installation on Ubuntu 24.04.

I followed this official instructions: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I put my old profile in the ~/snap/firefox/common/.mozilla/firefox/ folder and I set the correct values in profiles.ini. But sadly when I start Firefox all my passwords, extensions and history are not there. I lost everything.

I'm super desperate. Please tell me I can fix this somehow. Why is the official documentation lying?

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

Fx 124.0

Why am I getting these notifications? I have the latest version, but this prompt not only asks me to update, but there's no mention that it will install the beta 125.0 beta 1

Hi,

I recently setup a second computer and installed Thunderbird (Built 115.13.0 (64-bit)) again. I transferred all my preferences, but have this strange problem, that the appearance of the email list looks different. In the previously installed version it is a simple list with separators and in the new installed version every email is in a separate box. I included the screenshots as a reference.

I googled and searched the settings to align this, but unfortunately without success. Does anyone know how to change this?

Thank you!

About 3 weeks ago, I stopped getting email from ATT in Thunderbird. I am able to go online to the ATT mail and see my email, so it is something with Thunderbird. I've looked online for other suggestions and have tried several. Between everything, I've really messed things up and not sure where to start now. Last thing I tried was to delete the certificate and now I can't seem to add a certificate. Not sure if I'm suppose to create a new one or if there is one on my computer.

This morning I found some steps on how to create one. It had me go to the End-to-End Encryption to generate a new one. I didn't see that option, so I created a new OpenPGP key (not sure why I thought that would help).

Maybe the best thing is to try and reinstall Thunderbird.

I'm open to any suggestions.

Thank you.

i have for over 7 months that i have multible firefox crashes during the day, i only uses the pc for gaming, but now also for other stuff and use firefox for it.

Can anyone help me out ? and if more info is needed i would be happy to share, as long as this problem can be solved

I have an IMAP account which receives general email and email from a number of mailing lists.

I only want to see the mailing list email on my laptop, where I run Thunderbird (115.12.2).

So (on the laptop) I have Message Filters to move the email for each mailing list to a corresponding folder. But with IMAP I cannot add a rule to delete the email from the IMAP server. (I guess that is because folders in the IMAP accounts Inbox are resynced with the server ?)

What I'd *really* like to do is have a 'Retention Policy' (in the 'Folder Properties') to 'Remove From Server' -- so that anything appearing in such a folder would be removed from the server and/or not resynced with the server.

What I have done is create the mailing list folders in 'Local Folders'. This has the effect I want: it removes the mailing list email from the IMAP server.

However, the Local Folders languish at the bottom in the Folder Pane. I really want the mailing list folders to appear in the Inbox (for the account in question -- one of several I have).

Curiously: in the 'Saved Search Properties' for the Inbox, I can go to "Select the folders to search" and I can see all the Local Folders. I can select mailing list folders and when I 'Update', those folders disappear from Local Folders, but they do *not* appear in the Inbox. When I restart Thunderbird, those folders magically reappear in the Local Folders and still do not appear in the Inbox -- even though they are still selected to do so !

Even if it was possible to show some local folders in the Inbox they would not be in the Inbox for the account.

I do not know how Thunderbird knows which folders are local and which ones are not. Is it possible to change a folder setting somewhere so that a folder in an account's inbox is actually local (or is treated as local) ?

Since installing Thunderbird (on Linux Fedora) I have been really confused by and disappointed in the search functionality. I used Mac Mail for the last 20 years, I know that is pretty good, but I was told Thunderbird is at least function, if not as 'pretty' (some say).

I dont use the Quick Filter box as I have a ton of local folders and usually just need to find an email which could be anywhere, but i KNOW it's there.

I begun testing it. Noticed a few things so wondering if someone can advise if this is just me, or normal behaviour...

In the global search, I finally realised (i think anyway) that it does not actually search everywhere, far from it. For instance, I searched for emails many times and it said they don't exist, so i panicked thinking they were lost, but no, I dived into Deleted Items and there they were. I store deleted items for 3 months, and often refer back to them for past purchase receipts or similar in the rare occasion that I need it again for some reason.

- It doesn't seem to search (doesn't find anyway) in my Imap Deleted Items folder,. OR the Local Folders

- It isn't searching/finding emails in my Local Folderrs, which is a HUGE problem as 95% of my email is stored in those. Why wouldn't a global search find stuff in my local folders? I have tested it and confirmed it's not searching in any of them.

- I have ebay messages in my INBOX, from a username starting with perrie134 - I tried BOTH the quick filter and the CTRL K search, searching for 'perrie134' and then 'perr' and ZERO messages come up. Does the search not include 'from' info?

As far as I can tell, the search is not working at all. So I am hoping something must surely be wrong my end, but grateful if someone can comment. I can't use a program that can't find emails when I type in information included in 'from' and 'subject' areas, but at this point it's failing in every way.

Appreciate any advice/thoughts. Thanks

Im trying to put my email (prkirby@sky.com) on to thunderbird (version 115.12.1 64Bit) running on a windows 11 computer I have 2 other emails which run perfectly All my settings are correct, pop 3 incoming pop.tools.sky.com port 995 outgoing smpt.tools.sky.com port 465 both my username and password are correct, all these settings work when using outlook 2013 pro plus on a computer running windows 7 username and password also work when signing in to emails on different computers When I create the account the message I get is password/usename incorrect Any help will be gratefully received Phil

Outlook.office.com not refreshing automatically anymore and requires browser refresh to show new e-mails, etc... Works in Edge and Chrome just fine. Had this issue years ago and issue self-resolved, so unsure what resolution was then.

i am moving my accounts from outlook 2007 to Tb slowly doing one account at a time, making sure it all works, then moving on the the next account, i have already moved my hotmail.com & outlook.com emails accounts to TB successfully and all the inbox, sent and draft emails also went to TB with ease.

I now have 2 bigpond accounts i want to move to TB from outlook 2007, i am only going to move one at a time and once one is fully working , ill move the other one. So now i am trying to move one of my bigpond.com email accounts to TB, the account moved over ok, but its not bringing over any of my inbox, sent, draft, or other folders with it at all.

the bigpond account in TB works for new messages in and out, but none of my emails previous and older emails from outlook came with it. i have removed the account twice and still same issue. there was a warning or something that popped up during the first time i tried this with bringing the bigpond over to TB, cant remember what it said, but something along the lines of bigpond isnt trusted or veryifed certificate. i cant really recall. but maybe that is why. i copied the same settings from outlook 2007 to TB, i even tried setting them to pop for one try and them imap the next try, i still dont know.

is there a way to find the log warning message any where on TB as to what happen during the first try of adding the bipond account, maybe that will help you guys narrow down the issue. As that warning does not come up any more when i remove and try to add the account again, it just happened the first time. i though if hotmail can work easily ( being so old ) then bigpond should definitely have no issues. maybe its a pop or Imap issue, i dont know ???
