I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

I'm just getting started with Thunderbird on Windows 10. To test it, I set up my yahoo IMAP account xxxxx777@yahoo.com using a yahoo app password. It worked fine, so I deleted that account and set up my 'real' yahoo IMAP account, which is xxxxx@yahoo.com, using another app password from Yahoo. This is a different yahoo account, so I needed to get another app password. Again, that account worked fine.

However I then chose to delete that account on Thunderbird and return to using my xxxxx777@yahoo.com yahoo IMAP account, by getting a new app password and following the Thunderbird instructions for setting up an account. The trouble is that Thunderbird is now connecting to my xxxxx@yahoo IMAP server and receiving those emails and folders instead of my xxxxx777@yahoo.com emails and folders. I have uninstalled and reinstalled Thunderbird and rebooted the computer. Thunderbird 'account settings' is correct.

The first tab in Thunderbird is "email- xxxxx777@yahoo.com", and the folders that follow are from my xxxxx@yahoo.com account. Each time I receive an email on my xxxxx@yahoo.com account, it shows up in Thunderbird under my xxxxx777@yahoo.com account.

I'm stumped.

Thanks, David

I have to manage a number of joint email addresses which are outlook.com addresses, so I have them all installed on Thunderbird.

Up until recently, it worked fine, although every few months Outlook.com would not allow the sync because of some security issue (wanting an alternative email address, wanting an alternative phone number, wanting me to confirm that the last sync was me). I would sign in to the email account on a browser, fix the issue, and then it would work again.

As of a few days ago, Thunderbird is showing the "Login to account XXX failed" and "Login to server outlook.office365.com with username XXX failed" for maybe a dozen of the addresses every time I open Thunderbird. If I login to the email on a browser, and force Thunderbird to "Retry" several times, it will sync the account - but the next day, the same issue arises with the same account. When I check the account activity, it shows successful automatic syncs.

Is there another setting I need to check or change to make Thunderbird work with Outlook.com addresses?

I have 4 different gmail accounts that I use thunderbird to manage, along with local folders. Starting today, I cannot send messages. I get a dialog box with no error codes, underneath is another dialog box showing send progress with the eternal circle. Have rebooted, made sure each account has a unique SMTP server description. Worked fine until today. No updates that I know of.

For some reason, whenever I have multiple tabs open in Thunderbird, it will seemingly randomly open a new window, interrupting whatever I'm doing. What seems to happen is that the new window will contain the tab I was working with (address book, settings, etc.) and a tab for my mail, but that mail tab will have switched to a different mailbox. And then the new window that opened behind the other one will have a tab for my mail focusing on whichever mailbox was selected before.

This is driving me absolutely crazy! It keeps interrupting what I'm doing and makes me anxious to do anything in any tabs in Thunderbird. I need to fix it!

Any idea why this is happening and what I can do to stop it?

My TB repeatedly downloading all the emails in my Inbox, it is slowing down TB and can't access and reply to current email due to it. Is there any solution to it without losing my data?

greetings to the forum. TB 115.7.0 (64 bit) on windows 10, 32 GB RAM, intel i7-6700 CPU@3.40GHz I signed up for an account on the newsserver astraweb.com which has a very high message retention, around 21 years in the groups I subscribed to!!! in two groups I subscribed to, it downloaded 1410000 and 3031000 headers (no messages)... since after this massive download it was slow and unresponsive often, I repaired the folders of those groups and deleted the startup cache... in response the TB re-downloaded everything again, remained not responding for about 20 minutes and during this process used over 20 GB of RAM memory (see attached image). now it's using about 8.5 GB RAM, but every time I click on one group or another of astraweb it freezes with a "not responding" message until some mysterious task finishes... I could try to limit the number of headers downloaded in the account settings but I will only do it if I have to... If I don't find some solution, this way TB is almost unusable...

before posting on bugzilla and before deleting the older headers, do you think there is anything else I can do to avoid freezing TB on that server?

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

Since the dawn of time, the Compact folder command on the folder context menu has compacted just the selected folder. However, I have noticed that in the latest Thunderbird version (I'm using 115.6.1) the Compact folder starts automatically compacting all subfolders under the current one. This is a big problem for me: under the inbox, which I need to compact fairly often because all messages pass through it, I have literally hundreds of subfolders, some of them dating from more than 20 years ago, when I used Netscape Communicator. Those folders are "read only" (I only have them for reference), and I do not want to modify them in any way, to avoid risking their contents. Thus, I DO NEED for Thunderbird to stop compacting subfolders automatically. Is it possible? How can it be done?

Also, after a folder compacting has started, what's the best way of cancelling it, short of closing Thunderbird? I understand that the compaction process is quite safe, as it copies all data to a fresh file, but would rather not risk data loss.

Suddenly today Thunderbird won't access either of our Hotmail accounts. Error message reads "Login to server imap-mail.outlook.com with username my.name@hotmail.com failed." After several prompts to Retry/Enter New Password/Cancel, I even put the correct password in with no success and eventually received another message "Server has disconnected. The server may have gone down or there may be a network problem." Neither of these are true: I can access the server on my browser so I know the password is correct. Both my late husband's and my hotmail accounts are affected this way. Help! I am nearly 80 and not terribly computer literate and somebody else set Thunderbird up for me years ago because I wanted to be able to archive my messages locally (offline) and now it's suddenly stopped working.

Since the latest thunderbird update 115 I have multiple crashes & black screens, before this it was very stable. I have been using this since 2015 I think with little problem until now. If nobody else is having problems with 115 perhaps I should just use windows restore to go back to Dec 10th 2023. The only alteration to settings I made to try and fix it was to untick "use hardware acceleration when available". It made no difference.

Hi, my mailbox on the server is set to 5Gb. However the size of the IMAP directory of this mailbox on my hard disc is almost 22Gb. Sometimes I occured the situation that the mailbox's size on server lik 500Mb the IMAP catalogue took 80Gb of disk space. What might be the reason. Using 'cleaning' option does not help. Any thoughts? Mirek

I made a backup of the email, but now when I try to restore the backup, it gives me the error "Unable to open the summary file for Inbox on email@example.com. Perhaps there was an error on disk, or the full path is too long."

I did the repair folder but the error shows up again, I reinstalled thunderbird, the error is the same again.

Can someone tell me how to do a restore backup?

Thanks

Thunderbird can't seem to remember who I am! For the past year or so, every few weeks, I open Thunderbird to find that it doesn't know who I am. My entire account has seemingly disappeared! The first time this happened, I nearly lost it. I thought everything was gone. After doing some research, I discovered the likely problem was that the prefs.js file in my profile folder was corrupted. Going back to a backup (thank goodness for backups!) and copying an older version of prefs.js to replace the corrupted one fixed the problem - all my emails and folders were back as they were before. Whew! Until it happened again. And again, and again, and again, etc., etc.

Since this is a well known problem (I found the "fix" noted above in Mozilla help), I assumed at some point there would be a permanent fix. But several iterations of Thunderbird have come and gone since then and the problem remains. I have used Thunderbird for nearly 20 years, and have loved it. But if I don't find a solution for this problem, I may have to abandon the platform. I can't afford to have my email client forget me every few weeks. Resetting the prefs.js file takes time, and alarmingly it doesn't always work! A few times I found my backup prefs.js also failed and had to rely on an even older backup which can sometimes be problematic if I changed any settings in the interval in between. I REALLY hope someone has found a more permanent solution to this issue! If you have, please post it and let us know where to find the cure for Thunderbirdheimer's!!

I am asked to get a new password from my mail server (AOL) every day when trying to send messages. Have to log on to AOL, ask for app password, enter at Thunderbird. DAILY!
