When adding a link in the composer I get a large image.

I have tried to adjust the page code to give me a more suitable size however it seems the TB overrides the size

My page code reads <meta property="og:title" content="It's complex from 1948 to 2023">

   <meta property="og:description" content="#672">

Several days ago we inadvertently deleted batches of emails from our two Thunderbird Gmail accounts on our PC and Apple devices. The lost emails were duly recovered but only after having to change my Google password. However one of our Thunderbird Gmail account will not download any new messages coming in. Ultimately we deleted that account from Thunderbird, intending to reinstall it. We deleted the account by pressing the Red button in account settings. We confirmed that messages are received to Gmail's Web page Inbox Now when I attempt to reinstall the account and press Add Account, I get the UNABLE TO LOG IN AT SERVER MESSAGE shown below. The "Your Full Name" I am putting in is the name on the Google account deleted from Thunderbird, and the password I have tried is my new Google password. I have tried the process of not adding in the password until requested to do so but this did not work either. Any suggestions please?

'unique identifier' error and Inbox thinks it a draft folder. But only on one account. Messages to one of my mailboxes says it's coming from another of my email accounts, not the sender. If I right click the message in the Inbox I get an Edit Draft drop down. If I select 'open in another window' the From is correct in the new window. If I open an email in the Inbox the From shows coming from one my accounts. Started yesterday and I tried various ideas from faq's. Thanks!

I´m well trained employee in user support and server administration for more than 30 years now. So long for my skills... I´m the administrator of a Microsoft 365 tenant. A user asked some days age, as he can´t login into his M365E3 account using Thunderbird. I tried this scenario in my private Thunderbird profile and indeed I get an weird dialog box. I can insert my password above the first line, input above the second line is readable in clear text, the checkboxes are selectable, but no button for continue. I have examined https://support.mozilla.org/de/kb/microsoft-oauth-authentifizierung-th..., but have no success. Whats going wrong here and how can I help for debugging? Environment: TB 147.0, disabled extensions, Windows 11 pro german 01-2026 patch M365 account with MFA, (Microsoft authenticator app as primary option)

My pc calendar display is blank. I can create new event in Thunderbird on my pc and it is immediately appears in my google calendar on my mobile phone, but does not appear on my Windows 11 PC.

I'm using Thunderbird 140.6.0esr (aarch64) on a 2024 14" MacBok Pro running MacOS 15.7.3 (24G419).

I manage fourteen email addresses, with most of the traffic going to one primary account, either by direct addressing or forwarders from others of the addresses. Maybe not the most efficient setup, but it means I don't have to scan 14 different inboxes to find the messages I most need.

I currently use ±89 filters on this primary account to file messages in a LOT of mailserver-based folders, and a few folders on the laptop. ±90% of the traffic gets filed in server-based folders so I can use any device to access message history. (I should probably note that these filters and message-threading don't always play nice together.)

For a long time, one of the message filters I'll call "Filter BS" successfully filed specific messages in "Folder BS," a server-based folder 2 levels below the inbox. Folder BS also has 2 levels of sub-folders within it for annual and monthly filing.

Some time ago, I began to have problems with messages of many kinds (subjects/sources/etc.) going missing. Eventually, I searched and found them in Folder BS. In response, I deleted Filter BS, looked for but didn't find other filters responsible for these unexpected results, and managed incoming BS-related messages manually. But despite Filter BS having been deleted, non-BS-related messages still get "lost," meaning incorrectly filed in Folder BS, which is acting like a rogue black hole, sucking up everything that gets too close. I have not been able to identify any criteria for what turns up in Folder BS beyond "lots of stuff that doesn't in any way belong there."

Speculating that something's "off" with the BS folder's directory in a way that would be nearly impossible to fix, I'm trying to figure out the least inconvenient, least risky way to solve the problem.

Not knowing other ways I might compound the problem by making big moves with the MANY messages archived in the BS folder's 7 annual subfolders and their 12 each subfolders; and not knowing how to back up server-based in-box sub-folders, I'm stuck at an impasse.

How should I proceed?

Thanks in advance for any input.

Why are older emails disappearing from the Inbox? It didn't do this when I was using Windows 7SP1. Now I have Windows 11 and it seems the Oct and Nov emails I had have disappeared. Only Dec emails are in the Inbox.

Some senders for example Tangle go straight to my trash and if I move them to the inbox it immediately moves it back to trash. I do not understand what is blocking this nor how to do anything about it. Some send such as Erick Erickson generally go to inbox, but not always. Sometimes it goes to trash again.

Same Topic slightly different question... when I tell Thunderbird to delete all messages older than one year it does not do it. I do not know how to solve this problem. I do contribute to Thunderbird and thank you very much for any help that you can give. Don

I have a professional email address and a gmail address configured correctly in thunderbird. I also have a number of google calendars configured in lightning using the built-in google calendar support (i.e., I am not using the old google calendar plugin). Until recently, when I received and accepted a calendar invitation sent to my professional email address, thunderbird would ask to which calendar I wanted to save the invite. I would select the calendar I wanted and it would be saved appropriately.

A week ago, I created a new google calendar and added it to thunderbird/lightning using the built-in google calendar support. Now, when I accept a calendar invitation, it automatically goes to the new calendar (which is generally not appropriate) without asking me to choose. Furthermore, I am unable to edit these calendar events to change the calendar they are associated with. I have checked the properties of both the new and old calendars and they look the same.

The only seeming solution I found was to make the new calendar read only and disassociate it from an email address, and then undo both those options. For the time being, this operation seems to have gotten back the option to select which calendar invites are saved to. But I would still like to know if this was the correct solution and better understand how thunderbird chooses to save event invitations.

Window 11 desktop. Just downloaded and installed Thunderbird. Unable to type anything in to Calendar . Can only create event and that is unable to pick a time of the day just ends up at the top

Thunderbird has managed to keep all the message headers however the body of EVERY email is now empty. I had archives of email going back to the 80's and it's all gone. I tried to import backups again but TB throws away the body of the messages.

Note that there are many different email address formats in use from regular TCP/IP, XNS, UUCP, Mainframe 8.8, and others. The headers are there and show the addresses but the content is totally empty for every message.

Before TB gets a hold of them, I can read them so I know the data is there and it is TB that is removing it.

Please help

I changed my Windows 10 Thunderbird password 3 weeks ago. Every day since then I have not received a single email on my S23 Samsung cell. When I go to log into my Micros account to enter my password I do not have and cannot add or replace an old password. How about I make a donation to Thunderbird for an answer that works?

While reorganizing and renaming a local mail folder it has become inaccessible from Thunderbird. All the other folders are fine.

The folder name is BSW and the BSW file is present, so are the .msf and the .sbd. 1. I tried repairing the folder, no difference. 2. I've tried shutting down Thunderbird, deleting the .msf and restarting. No change in behavior but the .msf file is recreated. 3. I tried shutting down Thunderbird and renaming the files. No change.

Name Thunderbird Version 140.7.0esr Build ID 20260109054016

Is there another way to get Thunderbird to access the folder?

I'm using the latest version (145) and I've setup my office 365 email account. I'm trying to setup my calendar account as well but when I enter location, username and password it says that my credentials were not accepted.

I assume this means that TB is using legacy un/pw authentication which is no longer supported instead of OATH2. There is, however, no option to select OATH2 in the calendar setup process (like there is for email).

Are office 365 calendars supported by TB 145?

Hi All,

Just wondering what the roadmap is for multisearch functionality?

I might be a bit dim, but how do you actually search the support forums, as I suspect that this question has been asked before. There are no results returned for multisearch or RFC 7377 or ESEARCH.

Also is it possible to return search results as a vertical list instead of tiled responses, there's a reason why google doesn't do this.

we are unable to sign into tundsrbird using correct creditials. we worked with geek squad and they senr our mail to webnet. the tech told us we would not lose any email that were in thuderbird. when we ckecked they were all gone. there is very inpotant information in there. We would like to restore thunderbird and retrive our lost emails.
