While managing my Thunderbird Inbox, I inadvertantly transferred a chunk of Inbox messages received from my MS Office365 Outlook account into the trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails into the Inbox. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several fixes. Within Outlook, I created a new folder and moved the recovered Inbox mails to that folder. This was done in the hope that this folder will then sync properly with Thunderbird. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are deleted again from the new folder on OWA.

I also deleted the Outlook account (including all stored data) and recreated the account in Thunderbird. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again. Finally I went so far as to uninstall Thunderbird completely from my computer and reinstalled the software. That did not fix the problem either.

I will also provide another observation: in the past when I have recovered individual emails the same behavior has occurred. Seems that when Outlook or Exchange places a deleted email into the recovery queue, there is a change in its identify such that TB now views it as a deleted message.

Any suggestions on how this can be fixed?

Best regards

v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

v115.10.1 32-bit Changed isp and email completely, and wanted to change both server name and user name. But editing server name and leaving that field I get a popup wanting to restart - problem is I need to change user name as well or no go

So it starts to try and login but fails of course, since user name need to change too.

This really need another approach, maybe not so automatic.

Changing focus from first field to next one should not execute restart. - just when leaving second field if any of first and second is changed

So going through all accounts and failed logins etc all the way is cumbersome. - dual restarts every account

Not sure where to put bug reports like this. Thanks.

Now and then, when I press the Enter key, Thunderbird moves the current email message from Inbox to Trash instead of opening the message in a new tab.

I am using Version 115.11.1 (32-bit) on Windows 11.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

I am writing to let the community know that, at least in my case, the guidance from TB 1/2024 KB article on Qauth2, [and linked Microsoft article], didn't solve the odd password behavior that began around January, 2024, between TB and my Microsoft hotmail account--which had worked perfectly with TB for maybe 10 years?

Beginning in January I typically received an error message that SMTP server login failed; please enter password. But after fixing that as per the KB article (first trying to maintain normal password, then when that wouldn't solve it, turning on 2FA, switching to Qauth2 with cookies enabled), it turned out for me that with Qauth2 and 2FA, I could send mail okay but then the Outlook.IMAP server would not connect so receiving emails stopped. Several times after this failure I tried switching back to normal password AND turn OFF 2fa in order to get Outlook.IMAP to reeive email...but then SMTP would keep requesting passwords, and every day or two i'd get a repeated request to reenter the Imap server password for receivfing also.

The only stable fix I found after weeks of livign with this and debating abandonment of TB came when I turned 2FA back on, requested an app password from my Microsoft Account, changed TB Server settings back to Normal password for SMTP and Outlook.Imap, and then entered the App password when prompted by TB for to eonnect with server for receiving and sending.

This has worked fine and apparently been stable, without new reqauests to me for passwords, for 2 days, whereas all other fixes in past couple months have not lasted longer than a day or less before TB requests again that I enter a password to connect with my hotmail account. (All through this my gmail connection via TB ahas remained flawless, thought I did get a request for a gmail app password, which I obtained and entered--just once and all has since been fine).

I don't know why several careful step by step attempts to do everything in Mozilla's Thunderbird KB and Microsoft articles suggested didn't work--for a residential Microsoft account, whether I tried to follow guideance for those experiencing SMTP problem only, or the Imap server connection generally.

My only guess about why my Win 10 desktop installation is different? I have Outlook for Android running on two or 3 different Android devices also, perhaps that complicated things?  I also used to have a mirrored account (in other words, name@hotmail.com is my main account, but I also had a 2nd "nickename" acct with the same name, set up as name@outlook. com.  

(But I removed that nicknamed acct in case it was causing any of my authentication problems; made no difference. )

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Following suggestions from Jame and Matt (Thanks, guys!), I just installed T-Bird 115X on my Win7 computer, and successfully set up my primary e-mail account. I tried to import settings from my existing Outlook 2010 installation, and was instructed to set Outlook up as the default app for email. I did so, but now I get a "No profile found" notification from T-Bird T-Bird. What should I do?

Receiving email notifications in Thunderbird but they are not showing in my three different inboxes. Can read them via my mobile phone and if I log into my talktalk webmail? I am currently travelling and logged into a different IPS. There was no problem for the first couple of days. Could this be connected to the issue?

I can't send email from comcast.net account. Outgoing server (SMPT) ERROR. Comcast said problem with mozilla. What should password be for comcast smtp://smtp.comcast.net (smtp://smtp.comcast.net)?

The folder "popstate-1.dat" appeared under my email account below Inbox, Drafts, Sent, Archives, Junk and Trash. I have attached an image showing the folder located below Trash and above Local Folders.

Can it be deleted? Is it serving a purpose?

I recently deleted old messages from the various Local Folders folders.

Thank you.

I just updated to version 115.11.1 and now if I delete a message in my unified Inbox, sometimes it deletes and quickly comes back and sometimes it just stays there and I cannot delete again (delete is greyed out). Sometimes it does go into trash but still shows in inbox. In my server settings for that email I have the deleted email set to go to trash for that inbox. Suggestions?

I might give you more info..it seems now if I delete the message either by right clicking or top menu delete, it sends to the trash but stays in the inbox (sometimes it goes away but comes right back). If it stays in the deleted unified folder and I empty that trash folder it comes off the inbox. I have W10..and mail is from Yahoo Cox conversion that was working fine until this update today. Yahoo does seem to be much slower than Cox was so I am trying to be patient and wait but it stays in the inbox until described. The bottom taskbar icon still shows a mail in the inbox too even though it is in trash or even emptied. I have to close TB and go back or say to close window for this new mail icon to clear.

I have also discovered if i send an email from my iphone, eventually it comes into TB but if I delete it on my phone it is gone in TB but is NOT in TB trash but it does eventually show on my iPhone trash...the only way i could see this is to remove Trash from that email account in the unified section and then it shows in the regular trash for that email...seems maybe the unified folders have issues after this update ..this is getting so frustrating...and surprised there has been no response to this help question either..I checked my email here and it is correct..

Hi, I have just created a new folder within Local Folders, and want to move emails into it. When I click "move to" the new folder is not there. All the old folders are there - 10 of them. Is this a limit? Can it be enlarged?

In box emails on my desktop computer disappear without trace, mail that is in deleted & archive accounts are still there. These emails are still on the server as all these mails, thankfully, are my laptop

When I forward an email, the body text is gray just like the signature text, not black. Replies and compositions all look fine. Any idea how to correct this issue?
