I am an emeritus professor using the UVM email account tosler@uvm.edu<mailto:tosler@uvm.edu>, which I have used for many years. I use Mozilla Thunderbird (current version, “Eclipse”) as my email client and my account is configured for UVM’s Microsoft 365/Exchange Online service. After my most recent required yearly password change, although I can still receive email in Thunderbird, I can no longer send email. When I attempt to send a message, I consistently see this error: “Login to account ‘smtp.office365.com’ failed. Login to server smtp.office365.com with username tosler@uvm.edu<mailto:tosler@uvm.edu> failed.” Here are my current settings:

 *

Incoming (IMAP):

    *

Server: outlook.office365.com

    *

Port: 993

    *

Connection security: SSL/TLS

    *

Authentication method: OAuth2

    *

Username: tosler@uvm.edu

 *

Outgoing (SMTP):

    *

Server: smtp.office365.com (I have also tested smtp.uvm.edu with the same result)

    *

Port: 587

    *

Connection security: STARTTLS

    *

Authentication method: OAuth2

    *

Username: tosler@uvm.edu

I have reinstalled Thunderbird, and I have removed all saved passwords and tokens for outlook.office365.com and smtp.office365.com, restarted the program, and completed the Microsoft/UVM sign‑in prompt again. IMAP continues to work and mail arrives normally, but SMTP authentication still fails with the error above. Because:

 *

The configuration matches Microsoft 365/Exchange Online client‑submission settings, and

 *

IMAP with OAuth2 works, while SMTP with OAuth2 fails,

it appears that this may be a server‑side policy or mailbox setting, rather than a client configuration problem. What are my options? Does the University of Vermont have to change some setting on their end on my behalf? Thanks. -turner

Hi folks

When I tried to start up Thunderbird this evening, it has taken me to a set-up page. I seem to have lost all the settings, all my previous (about 3000 !) e-mails in my Inbox.

I obviously don't really want to set it all up again, but it has been working for years without a problem, and then suddenly this happens. I had now a 'warning' message saying that Mozilla Thunderbird wants to make changes to your computer - do you accept? I don't want it to make any changes unless it is to revert back to how it was.

Can anybody help me?

Thanks.

Will thunderbird run on an iMac With a M4 chip? I’ve tried to move the app from an older iMac to my new one and all I get when I open it is a message that it’s corrupted,

I accidently unsubscribed my current calendar. It does not list anymore, I do not know how to list unsubscribed calendars. How to re-subscribe it? (Window 11 w/latest Thunderbird). thanks very much.

One of the more aggravating aspects of Thunderbird's calendar is when an event alerts me that event grabs focus from whatever I am doing at the moment. I have no interest in having Thunderbird yell at me to stop what I'm doing and pay attention to the alert like a 5 year old. I am often deeply involved in other work and never appreciate Thunderbird's calendar interrupting me.

Is there somewhere in Thunderbird where I can tell Thunderbird that the calendar can pop open and make a sound but under no circumstances is it to take focus from where it is at the moment?

Before I recently (& reluctantly) upgraded to TB 140.8.1esr, I used to be able to paste the following in the Error Console to get a URI for an email message (or template) that I wanted to access from my calendaring app (EccoPro -- yeah, I know, one of those "from my dying hands" things, but it has never been equaled much less surpassed, just choked in the cradle by MS Office).

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

I would highlight the message I wanted to use, hit Shft-Ctrl -J, and paste that in the console.

I would get a notice with something like this which I could copy

"mailbox-message://nobody@Local%20Folders/Templates#10"

I could then put a clickable link in my calendaring app to run

"C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -mail "mailbox-message://nobody@Local%20Folders/Templates#10"

That message would open. Then I could hit Ctrl-E to edit it, paste as needed, and send .

This worked very well. I did not come up with it. I struck gold with Google and just copied it. With something similar to AutoHotKey I was able to automate it.

Now those URI codes no longer launch at all, and I cannot get new ones because when I paste

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

into Error Console I get

Uncaught ReferenceError: gFolderDisplay is not defined
   <anonymous> debugger eval code:1
   getEvalResult resource://devtools/server/actors/webconsole/eval-with-debugger.js:306
   evalWithDebugger resource://devtools/server/actors/webconsole/eval-with-debugger.js:218
   evaluateJS resource://devtools/server/actors/webconsole.js:895
   evaluateJSAsync resource://devtools/server/actors/webconsole.js:788
   makeInfallible resource://devtools/shared/ThreadSafeDevToolsUtils.js:103

If I had known what I was doing in the first place, I might be able to adapt to this version of Thunderbird. Something obviously changed in how the Error Console operates or something.

Does anyone know anything about what command could generate a message URI so I could open it from another app using the command line?

After recent update I can no longer send email on any of my accounts. A message popped up when I opened Thunderbird after the update stating I would need to change some settings, but message disappeared before I could read it all and could make changes. I need to know what settings I need to change to restore outgoing mail ability. my Email accounts are Gmail and Yahoo.

I'm changing email servers and need the best way to automatically backup my complete(multiple domains and user accounts) emails in thunderbird to a separate drive or local machine before changing servers. I would prefer an automated way to do this so I can continue to update backup file routinely

I already back up my profile regularly to a remote drive

Thank you in advance for any help you can give.

When Thunderbird injects a link preview into a message, it changes the text composition from Body Text (my norm and default) to Paragraph. This styling change persists even after I delete what look like the entire preview.

My fix for the current message is to select all and reestablish Body Text, then clean up left over mess.

My overall fix is to uncheck Settings > Composition > Add link previews when pasting URLs

Clearly HTML is required to create a graphic preview box in a message. I do not recall having turned link preview on to begin with, so I'm feeling opted in. Do Thunderbird updates download with this option turned off? ___

Another reason I eshew link previews is that they appear to establish connections to online assets without asking. How is this safe? As a software developer - and simply as a user - I have occasion to send people links that I don't want to connect with. To pick an easy edge case, what if I'm reporting a phishing or malware site? Just because I type or paste an URL into an email message doesn't mean I want to download anything from that source.

Curmudgery aside, I'm grateful for your help as always. Paul

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

140.7.1esr (64-bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0

Using TB 140.8.1 esr(64 bit) on Win11 Home desktop. My internet speed: About 40 Mbps up and down. All routine Win and TB updates installed when available. No changes in configuration, accounts, settings etc. except installing routine updates to TB and Win11. No problem with sending/receiving email. Sent mails go out immediately and appear right away in my sent folder. No problem receiving USENET news new postings to subscribed groups. I'm subscribed to 3 groups, using news.eternal-september.org. It used to be that when I wrote a reply to a post in a thread the msg would be sent within a few seconds. Recently and consistently, when I post to a group, pop-up notification tells me msg is being assembled. But progress appears to stall and msg often takes an hr. or more to appear in sent folder. Sometimes, it never appears in my sent folder but I can see it was sent because subsequent new postings to the same thread often cite my text and/or reply to it. My sent configuration: outgoing server: smtp.gmail.com port: 465 user name: my gmail email address - which works fine using google's web interface or TB authentication: OAuth2 connection security: SSL/TLS Any idea what's wrong? Any suggestions what to try to get back to prompt processing of sent postings to subscribed USENET groups?

I have been using Thunderbird with two POP3 Hotmail accounts for some time and I am trying to set up a third account with exactly the same configuration. However, both the automatic and the manual configurations failed. The new account receives mail, but the outgoing smtp server config seems to have a problem. Sending messages times out or keeps prompting for a new password.

The Hotmail account has POP3 and IMAP enabled. Thunderbird is set to receive all cookies. I cleared history and cache after every attempt and also temporarily disabled the firewall.

Any suggestions about what the problem could be?

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.

Hello everyone. Thanks for all your support.

A few weeks ago I started noticing a pop up window was occurring every (approx) 5 minutes in Thunderbird suggesting that I run a compact to save 992MB. I assumed this would stop happening after a few weeks and a few updates from Mozilla, but the problem has remained, so I'm coming here to ask about it.

Context: I'm on Windows 11. I have multiple email accounts that my Thunderbird reaches out to. At least one of the accounts is retired so reaching out to its historical server fails.

Reproducing: For me to reproduce it, I run the compact. Quit Thunderbird. Start Thunderbird. It reports 992MB can be freed. I let it compact. The main inbox disappears and reappears. I wait a few seconds and restart Thunderbird. It again tells me that it can save 992MB by running a compact.

What I've tried: I've tried repair on the inbox folder of the account I'm typically in. That didn't help. I have many other folders across many accounts and not tried to repair any other folders. I've searched the Mozilla help system.

Logs: It seems to me that a compact is probably failing but I don't know where to look for evidence of the failure.

Help. Help. I have been a very happy Thunderbird user for many years. I have linked my microsoft exchange calendar to thunderbird with the TBSync and Provider for Exchange ActiveSync.

With the upgrade to version 148, those add-ons no longer work.

So I downgraded to 140 ESR and those two add-ons were ok.

But when I tried to link them to my calendar, they would not sync. I received 401 and 403 errors from the automated setups. And the manual setup, asked for my password over and over again. They all worked beautifully before.

Please how can I get them to work again. I do not want to have to shift to outlook.

thank-you

Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.
