Microsoft tell me that I must use OAuth2 for my accounts, else I'll be locked out.

Server is imap-mail.outlook.com. If I select OAuth2, then I can't receive emails unless I reset back to Normal Password.

I'm also supposed to set my SMTP server (smtp-mail.outlook.com) to OAuth2, but this isn't an option on the drop down list.

Help, please!

Please Someone help ?

I have followed all the suggestions I can find, but my Thunderbird Calendar will not sync with the Outlook Calendar on Windows 11. I am using TB Sync, but every time I try to add my Outlook Calendar ? It refuses to accept my Password, even though it is correct, and the User name and email are too ! It shows as error code 401, and cannot authenticate ?

I have tried a suggestion to create an 'App Password' to use in my Microsoft account, but the options described do not exist in my account !

Can anyone please help ?

There's an article that says we can change where attachments are stored by going to tools, options, attachments. However, I have no "options" under "tools." Thanks in advance.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

I can't SEND on Thunderbird as of Update to Version 115.12.1 on 6/19. I was able to SEND on June 18th and left town for a week and when I came back could not Send. That could be a coincidence. Have Windows 11, with Defender Firewall and Security virus protection. I have TB version 115.12.2 up to date. I have checked with Spectrum for the correct configuration and currently I have as Description: SMTP Server (on top line); Server Name: Mail.brighthouse.com and Port 465, No Authentication and SSL/TLS. My User Name: e-mail address ends in @tampabay.rr.com and that is the same as shown on incoming server.

My husband just downloaded TB program on his Windows 8.1 which is my old computer that I've been running TB on for 15 years without a hitch!! ''''And he also cannot SEND.'''' It's very frustrating - we've tried changing server settings since Spectrum uses not only Brighthouse (which is the one they say covers the Tampabay.rr.com address) but they also use Mobil.charter.net and also TWC.com. I've tried changing them up but nothing works. I've tried changing Ports and anything I could change I did, but nothing works. I did get a couple of error msgs but they didn't help. Brighthouse timed out and another msg was saying that the email address I was sending as had to match the email address of the authentication and that didn't make sense as I have only had one address & (typed correctly in all places). I have called Spectrum more than once and asked for an upper level, however, they were no help at all saying they have no resp. for 3rd party etc. I HOPE YOU CAN HELP SOLVE THIS MYSTERY. Thank you!

My outgoing email stopped working suddenly. Incoming email works fine. I sent an email with a large attachment. It sent but after that I could not send anymore emails. I checked my password and server settings nothing has changed except I can't send email. I get a pop up window that asks for my password but after entering my password and hit enter I get another pop up window that says login failed please enter new password. The password works fine when I go AOL mail and enter it.

Exported address books and lists from 115.12.1 (32 bit) on W8.1, importing to 115.11.1 (64 bit) on W11.

Importing a named list into personal address book works - but the list itself is lost; they all go into one big address book. If I choose Create a new folder they all go into that - but again I've no list name, I can't write a message to the list like I used to be able to.

I can select New Mailing List, give it a name, but now I seem to have to enter each one individually, I see no way to paste in a list.

What am I doing wrong please?

Thunderbird crashed during a normal close (https://crash-stats.mozilla.org/report/index/3c0242b0-1a55-4eba-9f02-4a7bc0240126) and since then when I open Thunderbird, tabs appear for the messages I had open at the time of the crash, but they are all blank, and the tabs themselves are all empty. It is as if they are place-holders that are then never populated. I've attached a screen shot showing some of these tabs, with the crash report tab open and displayed.

About 1-2 months ago I reindexed folders due to mail apparently being missing and this resulted in a huge number of messages that had previously been dealt with becoming marked as unread again.

Ideally I would like the blank tabs to be reinstated and to be able to carry on working on my email from where I left off, but if this is not possible, I need to be able to identify the emails that were open in the tabs to be able to pick up the pieces. This is crucially important as I operate multiple accounts and it would be impossible for me to re-establish state any other way, especially in view of the earlier problem with email becoming marked as unread again. That would condemn me to needing to re-open many thousands of email items to identify those that may need action.

I renamed global-messages-db.sqlite which has been recreated and rebuilt but nothing has changed. The rebuilt file is significantly smaller than the original and if this implies that there has been data loss, I would rather reinstate the original file, if it is safe to do so.

My best guess is that the tabs are defined within history.sqlite and I have made a copy of this file but superficially it appears to contain a lot more than just tabs and it has been updated since the crash.

The most recent change I made to my Thunderbird configuration before the crash was the addition of the British-English dictionary.

The next most recent change to my Thunderbird configuration was the addition of a Proton Mail account using Proton Mail Bridge. I am accessing this account on behalf of someone who has sustained serious injuries and is unable to access it themselves. If this added account or Proton Mail Bridge is implicated in the crash in any way, I would prefer to remove the account and the Bridge software.

Many thanks in advance for your help and guidance with this problem.

as stated in the title, my HDD failed the other day and on recovery, my Thunderbird seems to have failed too.

I know (sort of) that it is all driven by the Profile.ini file.

But everytime I relaunch TB (even after what I think is an uninstall and a reinstall) I am getting : "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

I would be happy enough to have a blank TB load up and I would reconfigure my various email accounts. but I cannot seem to do even that.

I know there is a trick to getting to a Thunderbird configurator....but I have forgotten what it is.

Where does TB "look" when it starts up? how would I control that?

Hello,

I have been using Thunderbird for many years without any issues. I recently bought a laptop running Windows 11. On this machine, I have two accounts that cannot send emails via SMTP. What is puzzling is that I can retrieve emails through IMAP without any problems.

For another account I had to use STARTTLS to get it working. But on my Windows 10 machine, the same account is sending emails correctly with SSL/TLS.

Thunderbird is allowed through the Windows firewall and is on the antivirus whitelist.

I recently fixed an issue (connecting to Gmail) by allowing cookies, so it might be a simple fix like that.

Could someone help me, please?

Many thanks!

I recently installed Thunderbird on my mac. It seems to work well, except that it will not show my Archive folder (simply named "Archive") in the list of folders. I can see from my mail provider's web app that it is there and has my messages in it, and if I use search in thunderbird I can find messages in the Archive folder, but the Archive folder is completely missing from the list of folders. (I can see other folders, just not Archive.)

I did find how I can customize what folders Thunderbird will put Archived messages in, but that's not what I'm looking for. What I want is to be able to see the already existing folder with messages archived by other clients, e.g. the provider's web app.

Hello, i try to customise the thunderbird mail colors, but can't find any settings to that. I want to change the colors for "marked as -> unread" messages and the color for new received messages. Can anyone tell me how to adjust this? I tried to add the "userChrome.css" file in the self created folder "chrome" in my profile directory, but nothing changed. Can someone help me? I use Ubuntu 22.04.4 LTS version and the thunderbird version 115.6.0.

Hello, When sending a message from my gmail account within TB, I would like to automatically attach one of my other adresses as bcc: . How can I do that ?

As an alternative, is there a way to automatically copy the message in my sent folder in my gmail account to my local sent folder ? Using a filter perhaps , but I have been unable to create a filter that operates on the Sent folder.

Thank you, Alain Damlamian

I've been accessing ATT.net along with gmail.com for years now. Every once in a while, ATT don't accept my login password? Error message reads: "Login to server inbound.att.net with username pennsynut@att.net failed." And when I "enter new password" with the password from ATT.net, it still don't accept it. I vaguely remember doing something with ATT.net years ago. But why does it keep doing this "login failed"? I ask because if I wait a day, it will re-insert itself. When I check passwords in TB for ATT.net. All it shows is "mailboxc//(mailbox://). The gmails show smtp, imap & oath. But ATT only shows that one. ? How do I get the other passwords in there?

I have a verizon.net email account at AOL. AOL now requires use of a one-time-use "app password" to sign in from Thunderbird. This does work but it seems like now I will have to go through this process (going to AOL web mail and requesting a new app password) every time I reboot my computer or restart Thunderbird. Is this true?

I have a notice in the bottom right of my Thunderbird screen stating 103mb of 110mb IMAP total (93%) has been used.

I presume there will be consequences should this reach 100%!

My mail server is showing no issues of quotas being reached.

Is this an issue that relates to Thunderbird quotas?

Can anyone advise how I can reduce the 103mb total that is being shown?

Many thanks in advance.

How can we keep the month calendar visible in the Today Pane?
