I have several email accounts. One of these has a calendar linked to Google. I use this for calendar invitations from any of my accounts. However, I need to be able to send calendar invitations from the non-linked account like you can in Outlook. There, each time you add contacts to an invitation, you get an option to send From: Does Thunderbird have this capability? BTW I am not talking about setting default account. I need to be able to select when I create an invitation.

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

I have combined thunderbird and gmail, and it works different at my 2 pc.s, but that is ok.

But my original thunderbird relays on yousee and the adress from yousee.

What if I skip yousee?:

Can i still keep the email address from yousee to continue this combination?

I want to keep it, (the adress) if possibly, but not yousee??

This is the question ?

--,

Other words, not questions:

I must say: The configuration and the userfriendly way Thunderbird runs at pc is the very best - also the way You can mail to a group and answer between each other and all ( not easy in gmail)+ the way you can make maps= The worlds best.


But there are too many problems with yousee at the mobile, therefore I am thinking about shipping it.

( I also have Thunderbird at my mobile, but some new spams here, which does not shows up in Gmail or Thunderbird ...at pc.s) --- Best from Denmark/ Kib

Thunderbird keeps asking for password every time I connect to Thunderbird. One solution online said to go into settings, then security, on the password part it says to delete your password in saved passwords, click ok and then restart Thunderbird. The password I have is the same for my BT account and access to my BT emails. If I delete this password in Thunderbird will it affect the password to my BT account or is it just for Thunderbird?

I'm on a fresh Windows and the CPU usage is waaaaay too big. When TB is out of focus, it uses about 10% of my CPU. This can go up to 15% when the window is active. It's not doing anything, not downloading or compacting or anything.

After installing upgrade to 139.0.2, POP downloads failed. Last was on 6/19/2025 at 8:19PM. I deleted both saved passwords.. Went to AOL and generated a new APP password but there was no way to upgrade to it. I sent a test message to myself [ smtp] and AOL logged me in and TB generated the saved password oauth://login.aol.com (mail-w).

However even with shutdown TB and restart, there was no request for a POP password [ such as the new AOL APP generated one. What should I do? Is this a bug? I can read and use AOL mail on my browser [EDGE]. LKint@verizon.net

Greetings, I have Centurylink for my Internet Service Provider. They provide my internet service and email. I have been using Thunderbird for many years and know it quite well. My issue is this. About a year ago Centurylink had a major update with it's services. Since that time I've been having issues using Thunderbird for my e-mail. I'm currently using the 139.0.2 (64-bit) release.

Getting e-mail using Thunderbird is very slow and sometimes nearly impossible. I have to open the Centurylink e-mail and get caught up on e-mail using their e-mail service. They also want me to start paying for the e-mail service through Centurylink.net services.

Another anomaly is any sent messages I send using Thunderbird will not post to my Sent folder in Thunderbird. I use IMAP because my Desktop and Laptop share the same e-mail so I can have those readily available on each. I have been through all of Thunderbirds settings multiple times chasing a remedy to these issues without any results. This is very frustrating!

If I delete my e-mail account from Centurylink.net and attempt to use Thunderbird solely, would this be something you would suggest? I'm not familiar with how to SAVE Thunderbird e-mail files when changing ISP's or where the information is saved. That is very important to me before attempting too many changes in trying to find a temporary remedy to these issues.

I'm trying to hold out for any big changes for another year, due to getting fiber brought into our area and access provided to all customers in the next year.

I'm very excited about Thunder having e-mail provided exclusively. However, not seeing any target dates for this service, I'm trying to put off having to jump through two or three changes until our fiber is available.

Any help and suggestions would be greatly appreciated! Thank you in advance for the help!

John N. Miller

PS. I have just donated another $20.00 toward Thundermail and Thunderbird Pro projects.

I've moved thunderbird between windows 10 computers several times without any issues in the past, but I'm having problems now.

My old PC is running windows 10 with the most up to date TB. New machine has windows 11.

In the past, it was just a case of installing TB on the new machine and replacing the profile folder there with the one from the old machine.

Now when I do this I get "your thunderbird profile could not be loaded. It may be missing or inaccessible"

Using Nord VPN: All Gmail accounts are set up for imap on Thunderbird:

1) With VPN on, I cannot send/receive emails from/to my Gmail accounts using Thunderbird. 2) With VPN off, I can send/receive emails from/to my Gmail accounts 3) With VPN on or off and logged directly on mail.google.com, I am able to send/receive emails

And, yes, I have tried different port numbers and all server info is correct for imap on Thunderbird as indicated by #2 above. This change happened overnight and Thunderbird always worked faultlessly with Nord VPN for years. I don't think we can blame Nord VPN for this, given #3 above.

Your thoughts?

Hello,

I've been using Thunderbird for a number of years on my Windows 10 computers (one at a time). I used to have my email hosted by Cox, but it moved to Yahoo a year or two ago. At that time, I changed my IMAP and SMTP servers from cox to yahoo.

Suddenly, the other day, I'm not longer able to send or receive email messages in Thunderbird. I can still send and receive at Yahoo.com.

Here's the setup that I've been using in Thunderbird:


Incoming Mail (IMAP) Server

Server - export.imap.mail.yahoo.com Port - 993 Requires SSL - Yes

Outgoing Mail (SMTP) Server

Server - smtp.mail.yahoo.com Port - 465 Requires SSL - Yes Requires authentication - Yes

When I click on my inbox, I get a dialog box that says:

"Login to server imap.mail.yahoo.com with username davidmorrison@cox.net failed."

Maybe I should set up another account, with my same name?

Appreciate any help you have!

PS: I DO donate every year or two to Thunderbird...

Thanks.

I can get to the "stored passwords" box, but the email I need to change the password for isn't listed there. I have tried to send and receive messages but nothing makes a "enter your password" box pop up. All I get when it tries to retrieve messages from Gmail is a box to give my email, (just that, not a password) and then an error message that it won't work and there is no more information. I'm using Linux. I've had both this particular email address (as well as others) and Thunderbird for years, perhaps two decades, and I can't figure out what to do now. I was going to change all my email passwords for security reasons, but there's no way I can do that until I can get Thunderbird working with POP access again. Thank you.

Thanx for initial reply to my help request ...

My problem with Thunderbird downloading my Yahoo.com e-mails continue.

I've changed Yahoo.com passwords in the past with no problems. Thunderbird seems to have changed & become more complicated. I can't find the app password Generator for Thunderbird, but I'm able to see my Yahoo Password & the Oauth2 security protocol etc

So how in the heck can I get Thunderbird to work properly? And download my my messages into TB as it has done for years.
