I'm working in Windows 11 on my PC and can't find the menu tab to change layout of my email. The only instructions I see were posted ibn 2017. Why is this so difficult?

Microsoft outlook warned that I will no longer be able to use thunderbird after Sept 16th unless I use Oauth. I've tried changing settings to allow Oauth, but it's not listed as an option fot outgoing mail. Is this because I'm running windows 7? Is there any way around this, I want to keep win 7?

Thanks...

I've been using Thunderbird for several years now without any issues, and I currently have the latest version installed. I typically have multiple email accounts logged in. Recently, I tried adding a Gmail account, but it wouldn’t log in, showing the error: "Unable to log in at server. Probably wrong configuration, username, or password."

I’ve tried the usual fixes like closing and reopening Thunderbird, clearing cache files, and even searching online for solutions. Based on what I found, I’ve tried turning off VPN/antivirus, changing the default browser, clearing browser data, and, finally, uninstalling and reinstalling Thunderbird after removing all my email accounts.

Now, I’m unable to log in to any of my accounts, which were working fine before. Can anyone guide me on how to resolve this issue?

Thanks in advance!

HI, I have TBird 102.15.1 64Bit installed on several different PCs and laptops. On my main Laptop I checked the Roaming\Thunderbird folder properties and found the following: Size on Disk: 35.8 GB Contains 253,172 files and 1,533 Folders. Is their anyway I can reduce the size? My TBird seems to be running slowly and occasionally stalls. I do not want to switch back to Outlook client program, I am not a Microsoft supporter. I do know I could move mail to local folders but would that mean I could only access them from one machine? Thanks.

I've never knowingly installed a non-mainline thunderbird, but earlier this week I started getting the following when I open Thunderbird:

This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use. Use at your own risk, this build is the same quality as Thunderbird Beta.

Checking the version of thunderbird.exe It says its v131, which happens to be the same as the copy of Firefox installed. When I remove and reinstall Thunderbird it starts off as 128 but quickly changes to 131, even after uninstalling Firefox. (Also annoyingly, this stomps on the version in the profile, which 128 claims is no longer compatible, because Thunderbird isn't clever enough to save a copy of files when it makes "breaking" changes to user files)

I wouldn't being on 131 if actually worked, but it gets stuck in the handshake with my IMAP server, and doesn't even show the local folder caches. (It also for some reason shows the window controls on left side of the window title bar, rather than the right).

How can I restore standard functionality?

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?

Dear Thunderbird team I am an avid user of TB (home desktop Windows PCs), but I have been resting on my laurels on v78 for a few years now. I know, shame on me. I would like to upgrade to a stable "modern" release (emphasis on "stable" please). Can you please advise if I should aspire to end up on 115 or 128, and how I might get there ? From reading some older blogs, there is advice that says.... first go to v91, then v102, then v115, and so. That seems a bit tortuous, but I am happy to do so if that is still the recommended approach.

Also, can you advise on how I manage my Profile through all this, do I need to do various exports/imports as I move through these different versions, etc.

Many Thanks

Suddenly, I can't send emails from Thunderbird. I get this message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <rbrawer@nyc.rr.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500. Please verify that your email address is correct in your account settings and try again.

After closing the In Box, you'd think there'd be some simple obvious way to open it again. But no. The switch is hidden. Your Help agrees that the switch is nowhere to be found in the Menu Bar (as it obviously ought to be), but that it can be found in the Tool Bar.

The Tool Bar is not found in the Menu Bar either (as it obviously ought to be). Short of relaunching the program, what am I to do?

Did the designer of the interface have an addiction to video games? In video games everything is hidden, as though it were FUN to poke around looking. I have never played a video game. They are not fun. They are a waste of time. All commonly used email tools and windows should be accessible under the Menu Bar. Please fix your program. Meanwhile, please tell me how to open the In Box after closing it. Thank you.

I'm finding threads that include the correct emails for the subject, but also additional emails that do NOT relate to the original subject. How do I pull the other "subjects" from being in the wrong thread and create their own thread. See the highlighted emails in the attached image. Each color represents a separate thread that should stand on its own.

Thanks.

I have imported a certificate and setup my Thunderbird. When I try to send an email using encryption it won't send and Thunderbird displays the message ' End-to-end ecryption requires resolving certificate issues for XXXX@ddd.com'

How do I resolve this ?

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

This is the third time I wite a question but got no answer on the previous ones.... I created a mailing list but cannot send mails to it: it does not recognize the name and want à xxxx@yyyy.zz address. Pls help

All of a sudden yesterday 10/14/24, my email keeps saying not responding and freezes for at least 30 seconds before it will let me do anything. I have tried all suggestions that were given over the internet and none of them are working. I need help please! [edited phone# from public community support forum] Kelly

Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.

I have used Thunderbird for years without issue. In the last 2 days, it keeps crashing on one of my laptops (fine on the other). I sent a crash report, but I can't reopen Thunderbird. I tried both quitting and restarting. I shut down my computer and restarted it. I tried updating by downloading the latest version, but that didn't work either. I completely uninstalled it, reinstalled it, and it worked for a few hours. Now, it is back to the Crash Report.

Any suggestions? I love TB and don't want to switch to something else.

Hi I’m a very grateful Thunderbird user, for at least 10+yrs - and its always worked for me. I have done some pretty regular donations as well, to express my gratitude. On Wed my Thunderbird seized up on startup “Not Responding” and after about 5minutes of waiting I killed it with right hand top x. I have one imap and two pop accounts, plus about 7.2G of filed local mail The size on disk of my <profile> is 9.6G My connection to the mail server imap.sonic.net is a DSL ~ 1Mbits For the last two weeks, the writing emails, and saving has been a bit jerky – I assume having I’m Windows 11 latest (i7-9750H CPU @ 2.60GHz ram 16G.) with a C: drive 256G and d: 1000G. I have C:\Program Files\Mozilla Thunderbird - and been on the update channel, though not beta. D:\usr\a\n\AppData\Roaming\Thunderbird\Profiles\<MyProfileName> I copied the profile to a NAS for safe keeping. I ran through https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

and for all same result on startup – seized up. I reinstalled Thunderbird Ver 128.4.3esr (64-bit) – seized up. I created a new profile – and starts ok I started using “thunderbird -p” and choosing profile and “work offline” to not pull in the pop account. I copied in the old profile 10G, deleted contents of imap – still seizing up, So I started judiciously deleting older .sqlite though didn’t keep track initially – and then was able to startup, though sometimes also went into being seized up. I went through local folders – folder properties – repair folder. I still have the orginal 10G that was seizing up - so I could do some debug if useful.

A few weeks ago after an automatic update I ended up having Thunderbird version 131.0.1 installed, I have no idea how this happened. On opening I get a message telling me I shouldn't be using a beta version and that I should revert to the latest general release version (128.4)

Today when I had some free time I downloaded 128.4 and installed it. On opening it it says that I can't use a profile file from a later version with the earlier version. Is there a way to recover from this WITHOUT having to set up the whole profile again from scratch.

Meanwhile I have done a system restore so I am back with 131.0.1 It has not given me any problems so far. Is there a new general release version imminent that will get me back on track?

I would appreciate any help I am not a computer expert, just a user, and find Thunderbird a very good email client.
