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

Hi,

I am a longtime Thunderbird user. I have 3 email accounts that I check via Thunderbird. I am having issues on just one of those accounts since the 115 Supernova update. I see the message "checking inbox for new messages" but they are not downloading. I have ATT email through Yahoo, and I can log into Yahoo Mail (webmail) and see the messages there ... they suddenly are just not downloading to Thunderbird.

I have tried:

compacting folders Thunderbird safe mode Windows safe mode with networking turning my antivirus off temporarily moving all emails in that account Inbox to a backup folder

I'm frustrated and need to download mail - can you please help me?! Thanks!

Hi. I have an email purporting to be from Microsoft telling me that I will have access problems with Thunderbird from September onwards. Something to do with authentification. Assuming it is genuine (is it?) I have no idea what to do. It gives 'instructions' which are incomprehensible to me. I dont even know why this link is to Mozilla rather than thunderbird. I don't want to loose Thunderbird's calendar or stored files let alone the ease of access I currently enjoy. I need someone kind and patient to tell this novice how to move forward in a pedantic, non-terminology way who is happy to assume I know nothing! Please help! Brian

and I immediately began scrambling to get it back. I found this somewhere: "Don't Delete Files" is the preferred option because it saves the old profile's folder and allows you to recover the files to a new profile. So that gave me hope because that's what I had clicked (unfortunately, it was right before I saw the cancel button over on the right). That's what I get for being in a hurry I guess.

Anyhow, after 4 days of reading support forums and tons of trial and error, I'm no closer to restoring that profile than when I first started (although I've learned a lot about what does NOT work).

Btw, both my profiles have always been set up as POP3 at Gmail, although if I ever get this current problem sorted out I'll be shopping for a different POP3 provider. But that's another story.

I know how to create a new profile with Profile Manager. And I found the Profiles folders under both Thunderbird folder as well as ThunderbirdOLD folder. Have I been on the right track so far?

In the Thunderbird/Profiles folder, I don't see a folder with the deleted profile name (except the new ones (duds) I've since created ). On the other hand, I don't see the name of the profile that I did NOT delete either, but somehow it seems to be working just fine. Maybe it's the ".default" folder or ".default-release" folder? I've only ever had two profiles and I may have created the non-deleted profile first, so did that one end up being named .default? -shrug- I have no clue.

Anyhow, in the ThunderbirdOLD/Profiles folder, I also see ".default" as well as ".default-release" folders too. But in addition, I'm seeing a ".deletedprofile" named folder. So that's where I originally thought my several dozen email folders with several thousand emails and Address Book etc are hiding. But I've copied all the above mentioned folders into the several new Profiles I've created, on a trial and error basis but so far..... no luck. All I get when I open one is the new set up screen to set up a new pop3 account.... which I can do, but that's just starting from scratch without any of my saved data. I'm running out of ideas.

Where am I going wrong?

Hi, I have just changed my hosting company. I reconfigured my server settings and now I have TWO mailboxes: ray@raysloan.com (this is the one I want!) and another ray@nilgaut.o2switch.net All mails are going into the latter and this is NOT the one I want. If I look at 'settings' for raysloan.com at the top it says 'The following is a special account. There are no identities associated with it - account name ray@raysloan.com' !?

Please see the screen shots attached.

I am terrified of trying anything for fear of losing important mails. The last time something similar happened I lost all of my client information ! How can I get my primary mailbox back as my default mailbox and get rid of the ray@nilgaut.o2switch.net without losing mails ?

Thanks very much for any help.

Tonight I accidentally mistyped my password upon starting Thunderbird, so I chose "enter new password" and retyped it correctly. But now it won't download my mail, and I can't find any way to try entering the password again. (My password is not saved.) When I click "Get messages" the blue progress bar flickers at the bottom of the screen briefly but the Activity Manager remains blank. No mail is downloaded and there are no progress messages. There is also a small "null" note at bottom left, not sure whether that's related.

I have tried restarting Thunderbird several times, and restarting my computer entirely. No difference. I went into Settings / Privacy and Security and confirmed that there is no password saved. None of the settings have been changed. But I'm not getting an error message when I try to download mail, it's not doing anything at all (aside from the brief flicker of the progress bar).

I tried sending a test message and got the error "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.theworld.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." But none of my settings have changed. I can access my mail via web server so there isn't a problem with the ISP. But answering mail that way is really clumsy and time-consuming. I need my Thunderbird!

I am using Thunderbird 102.12.0 with Windows 10 Pro. I have been a happy Thunderbird user for many years (since 2015 I think) and have never encountered this problem before. I really hope you can tell me how to solve it, I am aware of several time-sensitive messages in my mailbox and I can't download anything. Thanks very much for your time!

Last night I created a new profile in an attempt to fix a problem with downloading mail. (It turned out to be on the ISP's end.) Tonight I briefly opened two copies of Thunderbird, one with the old/original profile and one with the new profile, to make sure the download would work. I was able to download my new mail to the original profile, so I moved last night's mail from the new inbox to my original inbox in the new profile, and then deleted the new profile since I don't need it. But now the past six months' worth of mail is missing from both my inbox and my sent folder! They both jump from June 13 to yesterday. I noticed it when I had the two copies open next to each other (those messages were missing in both copies), but thought maybe it was a merge problem and hoped they would be restored when I deleted the second profile. But they weren't. I absolutely did not delete all those messages and many of them are really important. Where did they go and how can I get them back? Help!!!

p.s. Sadly I haven't backed up in a while... :-(

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?

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

I've been using Thunderbird for many years with no problem. I'm now on v. 115.4.2 (64-bit). Suddenly, I can no longer send email. This is the message I get:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <sy777@maine.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.

I contacted Spectrum and received their recommended settings. The only difference I have is that my Authentication is set to NONE and theirs to YES OR CHECKED

My incoming email works fine.

Please help!

Using Thunderbird 102.4.1 - have not upgraded for a few days and program was working fine. Switched on today and inbox was rebuilt - and then all the messages are there but the From / To / CC fields are all blank on the message pane. When I reply to a message all the information is available. The From/To/CC is also visible on the summary pane. Same issue on all messages in every folder. Tried to restart in troubleshooting mode with addons disabled but made no difference. I have Header Tools Lite addon - disabled that but does not fix the issue. On Windows 11 and everything was working fine until this morning.

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

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.

I have used Thunderbird for more than 15 years and have always liked the way it works and promote it to anyone needing an email client, but the latest version 115 Super Nova is terrible. I don't like the font or anything in the update. Now I just found a new problem. Since last update messages show all previous messages from same sender with current message at the bottom of list. I have looked for a way to change this but have not found anything. It used to work so good and now it sucks.

I have been a Thunderbird user since 2004 and have been very satisfied with its performance. However yesterday something went wrong, at least i belief so.

Yesterday, October 5, 2022, i downloaded the Thunderbird update on Linux. After the automatic installation i lost all my files and folders. The accounts still exist and folders. I can view accounts and folders names in 'Go/Folders', but if i click the names nothing happens. How do I view my files or recover my files?

Thanks a lot in advance for your assistance Hans Schaap [email removed from public]

Hi. First, I have more tech problems than I can shake a stick at and I m dealing with concussion and screens (monitors, cell phone, etc) aggravates and I don't track as well online as usual, so I'm asking for help sooner than I would hoping y'all can break it down very smply for me. Thanks for reading.

Thunderbird v.59.2 on Windows Vista desktop. Yup, Vista :-) Cable provider died, so years of emails to addresses using isp-provided email addresses are in Thunderbird but can't use emails.

In short term got TMobile 5G wireless and it is hideous, beware! For now I use my cell as hotspot to get on internet on old desktop.

I'll list what I've tried in a sec, but here's my ultimate goal: I want to get AT&T fiber installed and hooked up on new desktop (Windows 11) and install latest thnder bird there and bring over old files. Before installing at&t I have to formally cancel with former cable provider (it's in an odd limbo). I've assumed it's better to cull all email addresses related to those email accounts before severing all ties.

What I tried: Followed this thread https://support.mozilla.org/en-US/questions/1255223

I can't upgrade to v60 with Vista. I modified advanced config and added strict config Boolean setting and set to false and added check compatibility 59.2 setting and set to false.

The email crawler add on still gives me not compatible error. I restarted Thunderbird and that didn't help, unfortunately.

What can I do?

Again, my two main concerns are 1) harvest email address on my dead email accounts so I can send notifications of my new email addresses and 2) prepare to move all Thunderbird stuff to new desktop once I have working wireless internet to facilitate.

Thank you for your patience with my explanation and any help you can provide.

Hi. My hard drive crashed. I have a new pc and the old drive is readable in a drive enclosure hooked up to new PC via usb. I have done the typical search for the appdata profile file, but I am not sure what I have here. I have attached a screenshot of the old drive and a global search on "Thunderbird". I am not sure where the profile file is residing. Any advice would be welcome. Thanks.
