After fixing the view problem of my email in Thunderbird (thanks for the F8 tip!), my email stopped downloading. I have no "prompt for password" checked. There isn't a primary password checked. I've confirmed the pop outgoing email is correct with the email provider (google). I can get into it without any issues and see my emails there.

I've re-entered the password for the pop outgoing email to no avail.

I have used Thunderbird on a MacBook Pro Max M4 for a while now. It worked fine until starting last Monday. Ever since then, I have to go to 1&1/IONOS e-mail on the web to send e-mails or use my iPhone and blind copy myself. It’s a pain going back and forth.

1&1/IONOS tech support helped me make sure all settings for the outgoing server (smtp) were and are correct. Tests on both incoming and outgoing ports are successful in the Thunderbird settings, so I don't understand why my e-mails are not sending. I have no problem receiving e-mails on Thunderbird. This problem on outgoing e-mails applies to both text-only e-mails and e-mails with attachments. Screenshots are attached.

There is 17.9GB worth of data. Do I perhaps need to delete some of it? I archive old e-mails offline once a year, generally in January for the previous calendar year.

Thanks, Tim

My big computer seems to be shut out of thunderbirds but my phone still works now that I contacted spark my phone now no longer works as well. please re-enstate my thunder bird emails onto my big computer and my phone. I prefer thunderbirds than using the xtra.web page. thankyou for your time on this. Janine van Marrewijk.

Functionality and usability issue: I use the Thunderbird for Android app as an adjunct to my desktop installation. Recently I had occasion to reply to an email in Android to one "to" recipient and needed to add two "cc" recipients, but found no way to add the cc recipients without deleting the existing cc recipients and having to input the entire (dynamic) group again, but then was also stymied by that. How best to handle this issue?

Other than that issue, the lack of desktop contacts synching, and the lack of spam filtering, Thunderbird for Android has been a huge help, so thanks to the developers for their dedication and hard work.

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 version 153.02esr. Since two days ago I cannot reply or forward messages. It pulls up the appropriate page but there is no box to send, the space is just blank in the upper left hand corner.

And worse yet, every 10-15 seconds I receive an alert that the connection has timed out. About a year-ish or so ago, our internet provider (Cox) sold our email service to yahoo. Although I managed to get all of the accounts (cox allowed our household 5) entered so that they all *received* mail, only one was able to send mail. The other four could only receive. Also, I could not send mail from either my google/gmail address or my very ancient yahoomail address. But all could at least receive mails. All in thunderbird, Excellent. As of yesterday, only one (a previous cox address) can receive or send mail. I tried sending a test mail to all of the other addresses, and no joy. If I get onto the yahoo main site, I can sign in with password and then must receive a text, phone call or other verification. And, of course, sign out of each, then sign into another, lather, rinse, repeat. Apparently I can also use a "passkey" which appears to be an actual "thing" that I have to plug into a USB port. I don't have one of these and have no idea what it is or how to get one. Since I've been composing this request, I've gotten 6 pop-up notices that the thunderbird server to yahoo has "timed out" - this is pretty annoying! And, there's another one! I am open to suggestions! Thunderbird has been great for getting all the emails in one place. Now, not so much. Help me!

Why is Thunderbird consatntly coming up with "Authentification failure while trying to connect to server outlook.office365.com"? It never used to and would download my hotmail emails perfectly until about a month ago. This is very frustrating, I have removed my hotmail account from thunderbird and re installed it, works for ocassionally the back to same old message authentification failure. What is going on with thunderbird?153.02

My Send short cut has disappeared.. I also have the "send later" add on to my Thunderbird. I seem unable to send messages. Is there a key board short cut to for sending mail? My old Eudora account used to have one a <Ctl> S.... (With Thunderbird this is Save, instead of send).

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).

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.

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.

When choosing to edit a sent message as a 'new' message, placing the cursor at the beginning of the message and pressing <Enter> does not advance the text.

It used to.

Placing the cursor at any other location within the message WILL advance the text with <Enter>.

I CAN add text by typing, but the <Enter> key does nothing.

The intent of placing the cursor at the beginning of the message is to add a line to the previously sent email.

The chosen option of 'edit as new message' should work with <Enter> regardless of where the cursor is positioned.

Any chance of this being addressed?

Thanks.

I am using ThunderBird 153.0 ESR for Linux Mint mint-001 - 1.0

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?

For whatever reason after the lastest Thunderbird update Windstream is refusing the connection to Thunderbird email client. I have gone through all of the delete .msf files for all of the inboxes tried adjusting server settings to no avail on anything.

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.
