How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

I just got a new computer running windows 11 pro. I downloaded Thunderbird, which I used on my old computer(windows 11), and followed the steps to set up my email. I know my email address and password are correct as well as the server settings and I keep getting the following error "Unable to log in at server. Probably wrong configuration, username or password". My email is .verizon.net which is handled by AOL. My husband also uses Thunderbird and verizon email and I checked the configuration against his computer and everything matches. I was able to get my gmail account added so it must be something with aol or windows 11 pro. Any help is appreciated.

I recently created a new profile, changing from POP3 to IMAP in order to meet the new Microsoft security requirements. All went well until I went to change my address book backup copy routine to access my address book in the new profile.. I cannot find any .MAB nor .SQLITE files anywhere! My address book is out there somewhere, as I can bring it up in Thunderbird, but I cannot find the actual file. What's going on?

Running TB 115.12.2 (32-bit), Windows 10 10.0.19045 Build 19045

質問お願い致します。 先程、誤ってメールを送信してしまいました。 受信側のメールも削除したいのです。 申し訳ありません。 回答よろしくお願い致します。

Please ask any questions. I sent an email by mistake earlier. I also want to delete the email on the receiving side. very sorry. Thank you for your reply.

My inbox has disappeared withe the latest update. Replaced by instructions for setting up my account. Having connected to the existing configuration, next instruction is to click on 'create account' - but there is no such box on my screen

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

Can I upgrade my Thunderbird 115.3.1 from 32 bit to 64 bit?

My Thunderbird has recently automatically updated to V115.3.1 but remains 32 bit. When I go to the Thunderbird download page there doesn't appear to be a choice of version.

I have spoken to my ISP and its confirmed, as have I, that I can log on to its website and successfully download my emails so the problem "must" lie with Thunderbird. I am not very technically inclined so would appreciate some advice please, thank you. My ISP technical person (at iiNet Australia) did say they were receiving a lot of phone calls today about email and "blamed" it on changes to Outlook? If this helps. Regards.

I think at some point I was able to send a private message. Or maybe it was just a reply to a private message that was sent to me. I remember something about clicking on a person's picture.

Thanks is advance for yoiur help. SweetTasha

TB 102.6.1 (64-Bit), macOS, DE locale

TB macOS with GUI on extras "Filter" edit lacks scrollbar in sub-window thus making amending / editing of filters almost impossible on the macOS GUI of TB. This mishap was introduced in TB 102.6.x only recently, I presume.

Please consider correct and fix asap.

Question: How to reasonably edit the textual config file for TB filters in cases like this?

When I delete 1 email, it happens quickly. When I delete 5 emails, it takes about 10 seconds. When I delete 40 emails, it takes 2+ minutes, when I delete 100+ emails, it takes 7+ minutes. What's going on? Seems to me emails, no matter how many I delete, should be deleted very quickly. What can I do to speed up the delete process?

I desperately (sobbing here) need someone to hold my hand and walk me through this!!! I uninstalled the newest version (115) and installed the previous version (102) because of an outgoing mail problem. It gave me a warning that the newer version changed my profiles and it's not compatible so I downloaded the new version again. The import screen doesn't look anything like what it says in the help files. I don't have an option for importing from a previous version.

Please rescue me. I run a nonprofit and I have deadlines and meetings next week that I was supposed to make arrangements for and I've been dealing with this for almost a week.

Thunderbird has changed one of my folders. This now has a different icon (see snip) and I cannot delete it as there is no option. Is it something that I've done and how do I correct it please. Many thanks

I still have v102 on my PC. I have read and see where there are a lot of problems with v115 - messages from users. So if I want to keep v102. How long will it be good? Is there a cut-off date that I will be forced to get v115? Is there someone knowledgeable with Tb that can call me and walk me through getting v115 set up like v102? I am not computer literate enough to be able to do that on my own. Or a way to get simple "step by step" instructions? Trying to read all the updates is way over my head. I am an 85 yr old man that simply wants to be able to read my emails without having to re-learn how. I've been using Tb and Firefox every since I can remember. Years and years. Can someone help? I can furnish email address and/or phone number if needed.

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

Thunderbird v31.4.0 Linux Mint Debian Edition 3.1.2-amd64 Cinnamon 2.0.14

When clicking on a link within an email, the system crashes and the monitor display displays jagged, diagonal lines. A cold boot is required. This can be repeated.

Same results running in Safe Mode.

Any ideas?

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.
