I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

I have thunderbird installed on my PC, and my main email account is a gmail account. I download from gmail using POP protocol (SSL/TLS connection security, OAuth2 authentication). I have been using these settings for a long time (15 years?).

This afternoon, thunderbird stopped downloading my messages. No error messages : just "no new messages to download".

I can see (by logging directly into my gmail account using my browser) that there are new messages on the server. They're not spam or junk, and they're not getting downloaded into my (local) spam folder. They're not getting downloaded at all.

I still have room on the google server (it's about 87% full), and room on the hard drive on my computer (about 3 GB).

Hi!

I have configured a EWS email account that requires manual configuration (I need to pass the override Office365 settings with application ID, tenand ID,...). When I select manual config I can configure the EWS server settings OK and the receiving part works OK. The problem is the outgoing server is not created OK (it is imap with password setup). I need to use the same EWS to send the email, imap is not allowed in the account. And I cannot configure the account to use EWS as the outgoing server. The outgoing server cannot be EWS and I need to setup one. So I'm in a loop.

For what I have read, thunderbird can send the email using EWS (https://support.mozilla.org/en-US/kb/thunderbird-and-exchange), but my feeling is that using manual setup (which I need to do to configure this account) breaks something internally and the outgoing is separated from the EWS receiving part. And I cannot configure back to use the internal EWS configuration in the receiving server part.

Can I do something to send emails using the same EWS configuration? What does the automatic setup to use the EWS configuration? Is there any bug for this situation?

Thanks in advance!

Thunderbird stopped downloading gmail this morning. It worked fine yesterday. I've restarted it 3 times to no avail. It says "Connected to imap.googlemailcom..." and it's been saying that for 2 1/2 hours now. Please help.

And please respond in non-tech terms. I am an old lady and I don't understand any of the stuff in the "help" section of your website. Still running Win10 because I can't handle the learning curve to 11. Please and thank you.

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

How can one setup a sending email server with same address and username but different passwords?

When trying to setup 2 different accounts i find a thunderbird limitation using API email password which have same smtp server address and username and only differs in password.

Is there a workaround?

Incoming mail on my windows 11 computer has begun appearing in the Sent folder instead of the Inbox. It appears to have started 7/26/26. When I right click on the message I see an option to "move to inbox again".

  This does not happen on my Macbook.

Seems like soon as a batch of emails download they all open up immediately or at least as soon as I open or delete one they all open. Never had this happening until just late this week.

Dear Ladies and Gentlemen,

the last few days my new mails didn’t arrive, perhaps because I tried to introduce new digital items. Please tell me how I can use thunderbird to get my mails; perhaps I have to change my settings. I find it strange that this occurs after I did a donation to you….

Regards,

Ich habe mehrere email Accounts auf denen ich Benachrichtigungen über email Eingänge erhalte. Auf einem email Konto klappt das nicht. Ich finde keine Lösung dafür.

Ich bitte um Hilfe

I have 5 emails setup on Thunderbird. I can receive emails for all 5 accounts. However, I can't send email on any of the accounts. I went through some of the old threads and tried to adjust the outgoing server, but I haven't been successful. Typically, I get a message like attached.

My account setting correctly are set to store send mail in send of the account. Now: - Shoud be: a send mail goes always there - Is A send mail goes sometimes to the local send folder

Pleas, tel me how to corect that.

Kind Regards, Ruud

I'm running the current version of Thunderbird on Windows 11 Pro. Several time in the last few weeks I have noticed periods where I don't seem to be getting mail. When I close Thunderbird and restart it I get batches of 10-20 email messages that had been delivered to my shaw mail account, but which Thunderbird hd stopped downloading. There were no obvious messages that it had failed.

Somehow I got 2 emails: gregory@gregorysantana.com and Gregory@GregorySantana.com The lower case shows a lock blue envelope and the upper case shows a lock red envelope. I don't understand the icon meaning of the lock icon and the color coding.

Further: I use command File, sub menu Get New Messages for All Accounts.

In the lower part of the overall panel, I see new messages downloading, but the new messages don't show up in either account.

How to correct, it is important.
