Hi! I´ve already informed my hosting service about this issue and it seems like the problem is Thunderbird instead. I tried to use the information given on your website, but nothing happened. I´ve had to log in and change the password multiple times now for emails to work, but after a few days I stop getting emails again. I don´t use Thunderbird for this email, so let me know if you need more specific information etc.

When trying to log onto my outlook email account, I received this notification: "Login to server outlook.office365.com with username holly.diamonddan@outlook.com failed" What do I do?

I use Snagit 2024 to capture the screen, since I'm in the support and documentation business. I just upgraded Thunderbird from v102 to v115.14.0. Now, when I press the PrintScreen key it is suppose to bring up the Snagit capture cross-hair but it doesn't - it always did in TB v102. The worst part is if I click a dropdown menu then press [PrintScreen] the menu always stays open. Because I cannot use the [PrintScreen] key clicking on the capture icon in the Snagit menu closes the dropdown menu so I cannot capture it.

What in the world is Thunderbird doing hijacking the [PrintScreen] key? Or is it? Why doesn't the hotkey work for other applications? Anyone know? Thanks,

Quick Filter is still extremely slow on the newest version of Thunderbird (128.1.1esr). I asked a question about this previously. It was reported as a bug (see links below) and it says in the report it was fixed, but the problem still seems to be there in the newest version. Any idea when this will be fixed, or if there is anything I can do about it?

There is a thread about it on reddit. https://www.reddit.com/r/Thunderbird/comments/1e6hryp/quick_filter_is_super_slow_in_128/

There was a bug reported, and it is listed as closed (solved). Here is the bug report thread: https://bugzilla.mozilla.org/show_bug.cgi?id=1908761

Thanks for you help.

Hi to all, after the latest update to 128.1.1esr (64-bit) the quick filter is very very slow and hangs the PC (WIN 11, 16 GB RAM and SSD) for 10-15 seconds. Thunderbird no longer responds and this happens all the time, also with different machines. The version before the update was just fine. Anyone with the same issue? Can you give me some hints/solutions? Thanks, Antonio

Receiving below error message

Login to server pop3.hughes.net with username xxxx@hughes.net failed.

I am a 20-year (give or take) user of Thunderbird, and it is getting almost unusable.

I am hopeful someone can help.

A lot of context....

My principal account is at Comcast (POP3; normal password), but a consulting gig has caused me to add a Outlook account (POP3; OAuth2). And I think that (along with Thunderbird updates within the past year) are the cause of my issues. And the only circumvention I have found is restarting. And yes, I have a large, multi-decade collection of e-mails in about 100 local folders.

Issues that appear intermittently:

1) Pauses (for instance, while composing e-mails) lasting up to 15 seconds where Thunderbird is unresponsive to keystrokes or other UI gestures. 2) Sometimes there are permanent "(Not responding)" lockups. Also there are times where the address book is inaccessible until Thunderbird is closed and restarted. Restarting is also the frequent cure for the persistent authentication issues. 3) Inability to access address book implicitly or via menu item 4) On start-up, generally both accounts get authenticated, but I keep getting nags to enter the Outlook password - If I ignore the nag, it pops up every couple of minutes. If I enter the password incorrectly, it tells me, but if I enter it correctly the login screen goes away, but login screen reappears within a few minutes. 5) Likely in conjunction with (4) above, I intermittently cannot send e-mails outbound to the Comcast account, with Tbird complaining about authentication; reentering the Comcast password does not help until I restart. 6) If (5) above happens, when I restart Tbird, I have to reenter Comcast passwords, even though I always select "remember password" 7) nstmp folders keep getting created.

Thank you for any assistance you can offer.

I am not able to search names in my individual Address Books. I have to scroll down the Contact List to find the name. How can I fix the Search feature in my Address Books?

Hi all,

I see lots of posts about emails disappearing but none exactly fit my situation.

I find messages disappearing especially when I move them to another folder. My config is TB115.10.1 Been using TB for countless years as an excellent app. After update 115 it has turned into a real mess for me. Always been POP accounts. Gmail is the server. All mail left on the server unless I delete it. I create a new POP account every year to keep track of emails by year. Have lots of folders to place the inbox messages.

For about a week now, when I mark as read and move a message to a folder. Say Paid" or "Cars", the message is no longer visible or selectable. I have read/unread/folder size turned on under my Inbox. So I know the missing messages are there in the folder but I cannot see them or select them. Some of the folders contents have completely disappeared. This a disaster for me. Has just started happening but was working fine before this TB update. Never happened before.

I will appreciate someones kind help.

my head is spinning with trying to understand. i changed the authentication to oauth2 but can't seem to find out whats wrong and my dislexia is making it so hard to figure out.

Have used Thunderbird with Comcast/Xfinity for over 10 years. I can receive all of my email on Thunderbird. About 6 months ago I started to not be able to send emails from Thunderbird sporadically, but it has escalated to the point of not being able to send emails of my comcast.net accounts at all. From my gmail accounts I can send messages just fine through Thunderbird. Three weeks ago I spent 2 hours on the phone with Xfinity. Reset all the passwords, checked all the settings, etc etc. For the rest of that day I could send all emails through Thunderbird. Ever since that day, same problem. I spent another 2 hours on the phone yesterday with Xfinity and they are sending my issue to a 3rd or 4th tier support person. They say there is no guarantee they will find a solution and that I won't hear back until Monday or Tuesday. Also this is the same problem on 2 different computers. One computer has the newest Thunderbird update to version 128.1.0esr and the other has the last version of Thunderbird as 115.14.0.

Here is the exact error message I get when I try to send an email:

Sending of message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-s2p-647654.sys.comcast.net resomta-s2p-647654.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.

The numbers after s2p- change for each attempt to send an email.

Believe me I have tried all sorts of different settings and I have read practically all of the solutions I could find on Mozilla's support forums and articles.

Really need help on this one. Jennifer

Thunderbird was configured to send & receive via Cox /yahoo mail. Worked until recently but can no longer send or receive.

Please advise. Best Regards, Leigh Wax

Thunderbird is taking a photo attachment from one message and attaching it to all new messages that I open, replacing the message text with the photo. Restarting Thunderbird and restarting the computer did not help.

I've tried restarting and reinstalling Thunderbird but no change in this blockage since Tuesday. I am running Windows 11 Pro and Thunderbird 128.1.0esr (64-bit). Downloading chunks of email from Comcast and trying to import them doesn't work. Please advise as I am stuck. I will check your answers on Comcast server as I can not read them directly.
