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

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

I have been running Thunderbird for almost seven years now, and these behaviors have persisted since day one on my laptop and desktop computer. First, I have five accounts set up. I am running two add-ons (Provider for Google Calendar, and Quicktext). I am currently running a snap version 115.12.2 of Thunderbird on both machines and they both are running Ubuntu 22.04 LTS. Plenty of RAM and plenty of free disk space.

Here are the two issues...

1. More often than not, when an email comes into one of the inboxes and I am viewing the unified inbox there are two copies of the same email. If I switch back to the actual inbox of the account it only shows the one. This is very aggravating and when you start trying the delete emails from the unified inbox it gets all hosed up and I end up having to go to each individual mailbox to delete the messages.

2. This somewhat relates to issue one... Sometimes when an email is deleted from the unified inbox, a blank record remains like in the image. This shows only one but sometimes there are multiple ones. Of course, if I go to that message's inbox it is not there.

I have tried all the common things like deleting the index files to let the indexes rebuild, comparing folders etc., and again, this has been a persistent problem since day one. Any insight or solution would be greatly appreciated.

Thank you! Mike

You have recently released version Thunderbird 128.1.1 in which you have changed the Compact View so that it is effectively no longer a Compact View, because the spaces have been increased between the Folders in the sidebar folder pane. I have been using Thunderbird for a couple of months and really liked the Compact View but now it has been spoiled. I don't understand why it was necessary to change this, and would be grateful if you would please revert the Compact View to how it appeared in version 115

Kind regards

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"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."

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

Up to now when I want to move TBird or update my TBird on a second PC I copy the profile folder <C:\Users\Elliott\AppData\Roaming\Thunderbird\Profiles\y6jsbo3s.default> from the Roaming folder. That seems to work well, though I sometimes have to update some of the layouts on the second machine. Is that still the best approach in 115.13? Will that change in 128?

As of today, my inbox has 7,563 emails, but none of them are displayed in the messages pane. I can see them if I go to All Mail, but I'd like to be able to use my inbox.

UPDATE SINCE THERE DOESN'T APPEAR TO BE A WAY TO DELETE THIS POST - I CLICKED "REPAIR" AND IT'S NOW FIXED.

Hi. I have approximately 26 folders in gmail and 34 filters that sort messages from my inbox to the appropriate folder on the mail server. I am planning on rearranging the filters and would like to know if there is a preferred way to optimize them. For example, am I better off having individual filters (say from several health providers) that end up saving respective messages into a 'Health' folder OR should I have 1 filter that looks for each provider in turn (OR condition aka 'Match any of...' ) then moves them to the 'Health' folder.

Not worried about performance, but more wondering if one method is more efficient than another.

Also, I seem to recall seeing in the filter help pages that it is preferable to have local storage for filters as opposed to having the mail server sort them out. Why is that?

kind regards, Kirby

As of December 1st 2023, one of my gmail accounts in thunderbird stopped working. Every time I check messages, I get the Oauth prompts to allow thunderbird access to the gmail account, I click through without error messages, and I can see the rights were granted to Thunderbird in my account, but Thunderbird is unable to connect. If I check saved passwords, I see it has not saved an OAuth password.

Things I have done: (1) Verified everything in this article: https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20 (2) Verified that IMAP was enabled on the gmail account (3) Checked the settings against my other gmail accounts which are all working, I don't see any difference. (And this account was working up until December 1st, along with all my other ones which are still working)

Anyone have any ideas what might be causing this?

I have been using Thunderbird for about 5 yrs and I strongly prefer it to Outlook. However, my PC has a small solid state drive (128 GB) and Thunderbird is creating very large files. The first time this happened I uninstalled Thunderbird and then reinstalled it and picked up about 20 GB on the hard drive. I have always installed it with the standard selections. When space became short again, I started deleting or moving files and applications. I would free up 15 GB, but the next time I booted up, that space would be gone. Using WinDirStat, I found a folder in my Users/myname/appdata/roaming/Thunderbird that was 70GB, more than 1/2 my drive. As info, the total space used for email on the Gmail server was only 13GB. I uninstalled Thunderbird but only picked up a small amount of space. I manually deleted the Thunderbird folder and picked up 70 GB in storage. Outlook seems to have no such folder, I also learned that deleting an email message in my inbox folder does not delete it from my Important or from my All Mail folders and most importantly the Gmail server. I was suprised to find that the all mail folder on the server contained nearly 200,000 messages. The only way to delete them was going to gmail using a browser and deleting them directly on the server. I would like to return to Thunderbird if these problems can be resolved.

I accidentally deleted an email account through Tools- Account Settings - Account Actions - Remove Account.

Is it possible to restore this account and its associated sub-folders.

I have installed Thunderbird on a separate PC and restored my latest backup, which unfortunately is 4 months old, meaning that I am missing 4 months worth of emails.

Might it be possible to link to files/folders containing my messages prior to the removal, perhaps by recreating the email account or might there be some other method in which I could achieve this.

Any thoughts you might have would be VERY welcome.

Kind regards - Deirdre

PS. We are using Thunderbird Version 128.0.1esr Build: 20240717233102

Hello,

Thunderbird keeps crashing. That is about all that I can tell you. It started this morning (/when I got to work I fist noticed it). I have not used any add ons. I have been submitting crash reports. Crash data avaiable on request. I uninstalled and re installed, same result; crashes immediately on start up.

Please assist.

Thank you

I am using Thunderbird 102.12.0 (but the problem may have started before the update) I have had this problem intermittently in the past but it only affected 1-2 emails but today it seems to be most of the emails in my inbox. It seems that multiple emails are being combined into one email so when I look at my inbox it will tell me who it is from and the title, but when I click on it the sender and title may disappear (or may not) and the email is multiple lines of text & code (not necessarily the body of that email it can be 1 or multiple other emails in there all mixed up with or without different sender details). I can view the emails with no problem on my iphone and using webmail so it seems to just be a Thunderbird problem. If I look at the email on my phone or web browser I can see it perfectly and forward it to myself and then it seems to be ok. All help appreciated! Thank you Jean

I've been a Thunderbird user for years. I have no idea what they changed recently, but it's incredibly, incredibly SLOW, almost to the point of unusability. Even something as simple as deleting emails.

I usually do these in chunks -- select multiples and delete. We're not talking about hundreds of emails at at time here, just maybe 5-15. Select them all, hit delete, and it should take just a couple of seconds to delete the messages. It did, in the past. But lately, it's taking so long that I could leave and make a sandwich, and when I come back, maybe it will be done. Maybe it will still be working, though, or maybe it will have locked up because it was taking so long.

It's pretty difficult to get work done at this rate.

I am running a Mac Mini M1, on the latest OS, after upgrading my TB I have just had 2 force quit because of TB. As you will see it is using over 40 GB of memory, normally between 500 - 600 MB

Thunderbird automatically updated to v128 earlier this week after I went to Help - About Thunderbird to check that it had updated to v115.14.

Everything seemed okay immediately after the update, but when I started Thunderbird the next day it was very unresponsive. Checking the Activity Manager showed that Thunderbird was indexing messages, but that this was happening very slowly. I let Thunderbird do its thing that day in the hope that things would settle down.

The next day when I started Thunderbird things were still bad. I tried Rebuilding the Global Database but when I restarted Thunderbird it was just as bad, if not worse.

I then turned off indexing in the Thunderbird settings and Thunderbird is now responsive and back to normal.

Is anyone else seeing anything like this? Any suggestions to fix the problem?

I am a long time Thunderbird user so my profile is very large with a lot of accounts, and has been through a lot of Thunderbird versions, so it is potentially more complicated than normal.

Thunderbird version is currently 128.1.0esr (32-bit).

Thanks

TB has been extremely finicky the past few days with send and receive. The biggest issue is that the Get Messages / Get All New Messages stops responding altogether - it works fine, and then suddenly nothing except (sometimes) the word "null" next to the online icon at the bottom left, and a pulsating blue progress bar in the Activity Manager area, that disappears after a moment.

A few times I have been able to "fix" it by going to Server Settings and changing Connection Security to None temporarily, but this doesn't work every time.

Another "solution" is to change the password on the mail server, which prompts TB to demand the PW. This is not a good solution, as the password must then be changed on any/every other device that connects to the mail server, and then the problem repeats after some period.

Other times, and per a suggestion on another thread with a similar subject line, clicking on the "go offline" icon at the bottom, generates a prompt to download emails before going offline, and this seems to cause a demand for password, which allows emails to be downloaded, but this also seems like a band-aid. What is going on here? Windows 10 64 Bit TB 102.11.0 (64-bit)
