I-Thunderbird Community Forum

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

I have no usable Menu options at the top of the Thunderbird email screen. I hit a wrong key yesterday and things such as Write, Reply, Print, Send, Delete, Junk, etc. have disappeared. I read some possible things to help but I do not have III on the upper right of my screen and pressing Alt when opening Thunderbird also does not work. HELP!

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!

I've been running Tbird on Windows for many years. About 2 weeks ago something changed, either in Tbird or at Microsoft, which stops me from sending to the Office 365 SMTP server. I can send and receive using Outlook on the Office website, but I can't send locally from Tbird. Error message screenshot herewith. I have tried every possible permutation of server settings, which currently are:

Server name: smtp.office365.com Port: 587 Security: START/TLS Authentication: OAuth2

MS support says these are correct, and they are at wits' end to understand what is going on. They asked me to ask Tbird support, so I am.

I should add that at about the same time I started getting SMTP rejections in Gmail on my Android phone, and miraculously that was corrected yesterday, without any action from me. There is something odd going on at Microsoft - does anyone know what it is? My other accounts on Tbird work fine of course.

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

Why is the VIEW menu missing the ability to turn off threads? Hate threads, always have, stupid idea. Sorry, but no. Where can I completely disable threads? I upgraded to 115 beta and all my accounts now have 'threads'... FML.

I run Thunderbird on a PC, and, to free up space on Drive C:, I have moved the contents of the folder Thunderbird in Appdata to Drive D:. I then changed my Server Settings, in Thunderbird, from C: to D:, and note that any new mail is indeed now appearing there along with those already transferred. This move could save me a valuable 6 gig of space, and more in the future, however, I am unable to remove that original Thunderbird folder entirely, notably I am unable to remove the contents of the Profiles folder, as it is still linked to the application. Notably with cookies.sqlite, cookies.sqlite-shm, store.json, mozlz4, aborted-session-ping and many others, which I note some have continued to be updated. I have been unable to find any other settings in Thunderbird referring to Drive C:, other than those in Server Settings.

I could presume that if I installed another version of Thunderbird on Drive D: and maybe moved those existing contents of the Thunderbird folder on C: onto Drive D:, and made those numerous settings changes to the App it could work. But I ask is there an easier way to complete this move? How can I complete this transition of Thunderbird from Drive C: to Drive D:?

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?

Can anyone let me know the 'shape' of a correct profiles file. I have a relatively small number of emails in the system (perhaps 1000 or so??) but my profiles file is a gigantic 4.5Gby with 63k files in 83 folders. I feel this can't be right. There are hundrends of 'mini files' that are meaningless to me. This large file seems to be giving Tundebird indegestion at times when it says that it can't transfer a file from one folder to aother. I guess I could scrap it and start again but that would obviously mean l lose all my emails and addresses. Is there any way to 'clean' the profiles file and reduce the size. The compact facility doesn't seem to do this for me.

Thanks, Terry

I have 10 email accounts in my Thunderbird 115.12.2 (64-bit) and I am using Microsoft Windows 10 Pro and all my sent, draft, archives and templates are going into a different folder. I want them to go into the folder from which the email was sent but they are all going into the email tinakeeling@att.net.

I have changed it to reflect the correct folder but then a few days later and every time I restart Thunderbird the program changes the folders back to tinakeeling@att.net

I have even unchecked the box "place a copy in" and when Thunderbird is restarted it reverts back.

What can I do to fix this issue?

See attached picture of what I am talking about

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!

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

Every time I download new version of thunderbird I suddenly cannot send emails, I can receive fine. It's so maddening ughh Once this happens I spend many hours searching support and it takes forever to find the answer. Some times it's a simple server setting change is the fix or adding @.... after the username but now this is not working

Please please help
