I have had messages about EWS support being ended from 1st October from the Beonex ExQuilla Add-On which I have been using for many years.

So I installed Beonex's new Owl Add-On which supports Microsoft Graph Protocol and migrated my Email accounts. However, this just renamed my existing account with "Old" at the end and created new ones which cannot connect!

The IT provider for the Email Domain will not allow the Owl Beonex App to connect, despite the ExQuilla one being used for many years!

They have now pointed out that Thunderbird natively supports the Microsoft Graph Protocol from Release 154. BUT I am on the ESR channel (as I need stable Email handling) and the latest ESR Release is 153.4.0esr!

So when will an ESR be released with Graph Support, as Microsoft could stop me being able to receive and send Emails any day as it is now past 1st October???? - Please let me know your timeline for the next ESR with Graph support A.S.A.P.

I do not want to install a non-ESR as I see that the latest Release 157.0.1 fixed a bug with the Graph protocol and 155.0 streamlined the manual account configuration. So I want stick with stable releases!

Also, do I have to add new accounts to use Microsoft Graph, or can I just change the configuration of my existing ones?

If the former, then I guess once I am happy I have all old Emails available (as I rely on Emails going back many years!), I can delete the original Accounts from Thunderbird, including the non-working " Old" ones created by the ExQuilla to Owl migration????

Thanks

I had my dad on Thunderbird, and migrated him to Evolution, after your horrible failure. I only wish there was a Mac version, I'm stuck on Thunderbird on my Macs. There is no way I can trust Thunderbird, after this destructive failure. They tried to force people off of apt, Linux, and put in hooks to have apt use SNAP, want it or not! When it force migrated him off of apt, which was NOT wanted, or asked for, it lost ALL of his Thunderbird data.

Not only are you not smart enough to realize that some people don't want SNAP, AppImage, FlatPak, or other crap sandboxed garbage, but, without giving them a choice, trying to force a screwed up migration, that obviously doesn't work, and deleting ALL of their data is unacceptable. Even if it hadn't lost all of his data, it wasn't wanted, and I would have had to undo the damage.

FIreFox is the same shit, forcing to SNAP garbage. Fortunately, I have him on Brave, so it's not really needed, just installed for backup, but not being used.

I had to create install scripts just to get them to install normally, no SNAP GARBAGE! It was not easy, because they still try to force migrate.

There are a lot of authors now coming to Linux, that know nothing about it, and don't know how to use apt, so they try that sandboxed shit, not understanding that's why a lot of people are abandoning Windows and Mac in the first place. But most, if not all of them, at least have a .deb to download, or options. This is the first software I have seen trick apt into installing SNAP, then deleting all of its data. And, yes, after searching the entire drive, the data was gone.

What you did is complete BS, and unlike some of those newer people moving to Linux, you can't blame ignorance, because you are not new.

Firefox said to update to 153.4.0 esr to continue to use Google Calendar. I did and was able to recover the calendar. But the upgrade lost all my emails and folders. Previous answers for lost emails have not worked. Please give me a step by step procedure to recover my emails. Thank you

Hello, So my thunderbird updated yesterday 10/1/2026 and since then it's changed my layout and also making problems in attaching documents etc. Is there a way to revert to the last version? Or does someone have a way to fix this problem?

Ever since the last update 157 when i open a conversation it open every single tab in that conversation and i hate that, cause i have to close every one to go to another email. this stupid updating thing is for the birds. Another thing that i really liked in past versions that whatever color tag i wanted to use would color the subject line now it just does a little symbol all the way on the right side. Can i uninstall a update by chance?

I thought I had opted for the release channel. But after a recent update, it seems I'm on the beta channel. I'm using a laptop with Ubuntu 24.04 LTS, Tbird was installed as a snap, and is updated automatically via snap. However, when I look at Help/About, the image says Beta.

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.

Thunderbird did update while Thunderbird was running. Notice no new emails a few hours later. Icon changed to text picture and all folders showing. Received request if I wanted text icon removed? Said yes. Everything gone. Went to program file, x86 file and only file in Thunderbird visable last nigher were update logs. Now gone, everything in Mozilla maintenance folders gone.

Appdata shows 8/10 profile. Mobile email link to Thunderbird down, not receiving.

When I up dated the latest version of T.B.. when switching form the index desk top page to read the email, the page is blank EXCEPT for "SWITCH TO: EXTENSION" displayed at the top of the page

The T.B. icon is not is not displayed

From the release page of Thunderbird - https://www.thunderbird.net/en-US/thunderbird/releases/

I see 153.0 (the first release) is marked as ''esr'. But from 153.0.1, there are both esr and release. I would be great to understand the reason behind this approach.

Thanks in advance!

Dear Foristi, after updating to V. 135 Oesr (64Bit), neither AOL mail nor Yahoo mail cooperate any longer. Passwords checked, correct. Other PC, not updated, still connects to AOL and Yahoo addresses without flaw. OS: Linux Mint, both PC have 8 GB RAM. Where did I screw up?

Thanxalot in advance -rick

I believe I downloaded 153, but I don't where to find it.

The information regarding Version 153 and downloading it is confusing.

One page states, "Manual upgrade to 153 is now enabled via Help > About", but when I go to Help > About, all I see is the current version and the statement that it is up to date. The recommendation on one page regarding 153 is to switch from Release to ESR, although the contrary seems to be the case for Version 153.

End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

I'm up to date on Windows 10 with version 151.0.1 of Thunderbird. My preference is to discontinue using Windows and move to Linux Mint. The Software Manager in Mint installs and manages Thunderbird updates. I like the idea of Mint managing my software. However, the latest version is 140.11.1esr. Consequently, moving my data from Windows to Mint is not possible. A profile problem is flagged.

I've switched off automatic updates. I'm wondering how long it will take Linux Mint to catch up to v150. One solution is to install v150 independent of the Mint software manager, but I'd rather not do that. I'm wondering if there are any workarounds.

French please !

Bonjour,

Lorsque je veux modifier la manière dont Thunderbird est mis à jour, il s'affiche ceci :

"Thunderbird est mis à jour par une autre instance" et il est impossible de le modifier car si on on choisit de le faire, le logiciel thunderbird corrige immédiatement et retourne à la configuration précédente (solutions/choix à cocher, mises à jour automatiques ou manuelles) !

Comment opérer S.V.P. ? Merci à vous. Salutations cordiales. Alain.
