Hi, IMAP Mail. My Domain Host sent out an e mail to update the server settings. I did it on one machine and immediately got this error. I went back to the old settings and things worked as they should. After about 5 hours with the online chat help and having added 4 CNAME records at their request things were still the same. They then said I need to pay $60 for a third party vendor to log onto my machine and find the issue. This point really got my back up. I added a new account using the all new settings and this one saves by default in the Local Folders. I added the account details to my works e mail which is in Outlook by company policy and it runs well with the settings they Domain Host provided. I have other machines still running the older settings that also seem to run just fine. I have tried to point the save location to the sent mail folder under the account that's having trouble and still it says no box yet when checking properties I see it has a server address. That is imap://****%40****.com@netsol-imap-oxcs.hostingplatform.com/INBOX/Sent The * are inserted by me to cover my e mail address. Thanks in advance for any help you can offer.

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?

Recently, when I click on Get Messages to download email from Comcast server I receive error messages. One error shows "Login to server mail.comcast.net with username X?X?X failed. Retry, Enter New Password, Cancel".. Second error shows "Sending of passwowrd for user X?X?X did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later" I spoke with Comcast tech support and they, of course, gave me the standard line that I was using a 3rd Party App for email and they could not support that and I could instead use the email on line at my Comcast account site utilizing the antiquated Comcast mail options. They finally attempted to help and after they researched the issue they suggested I change the Server Name setting form 'MAIL.COMCAST.NET' to 'IMAP.COMCAST.NET' and changed port from 995 to 993. I tried making those changes and was not receiving the error statements. But I also was not seeing ANY email downloaded or message indicating TBird was login in the Comcast server. I then changed the Server Name back to 'MAIL.COMCAST.NET' and port back to 995. TBird then correctly downloaded dozens of emails. When I tried to same thing the next day, though, the error problems had returned. Finally, I was looking at Tools>Account Settings and selected Add-ons and Themes in left pane. I noticed Bitdefender Toolbar was enabled under Extensions so I tried switching it to disabled. Voila, the program would once again download emails. But a short time later another try to Get Messages resulted in the errors again. Can anyone answer with changes to connect properly to Comcast for email? Any help would be greatly appreciated.

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

Is there anything I can do or change ? I have literally spent almost trying various things and I am the point of giving up and trying a completely different email client. There should be a seamless migration method but it appears there is not.

Long time (20 year) user of Thunderbird. I just upgraded to Thunderbird 115.7.0 (64-bit) on Windows 11 Enterprise. I'm using outlook with Exquilla authentication. Since the upgrade, when I view an email in the list of emails pane and I delete it, Tbird goes to the next email and displays it. However, that email is not highlighted in the list of emails pane. That means I cannot delete it even though there is a delete button in the email contents pane. I need to select it(highlight it) and then I can delete. Not sure what is causing this. Looked at a bunch of settings and posts and didn't see anything.

BTW, this used to happen to be occasionally on older versions of TBird but a restart would always correct it. Now that doesn't work and it seems like it it "normal" behavior.

Any help would be appreciated.

Thanks,

I re-installed Thunderbird today but did not save the local folders before I did so. The local folders have all disappeared and I have searched high and low for them. I have used all the old profiles, but that does not bring them back. I can get the old emails, but just not the folders. I did think that I found some, but those folders were empty. Does Thunderbird delete these folders when you re-install? This is really upsetting, as I needed the folders. I looked for deleted folders and restored them, but that did not help. Any suggestions would be gratefully received. Thank you.

Hello all. Sorry for this long posting. Sometime last winter, Comcast had a system security issue, forcing all users to change their passwords. As it turns out, they apparently changed their method of authentication, but didn't inform users of settings changes. Basically, their system requires a "Primary" email account for account maintenance, then secondary users can be added and maintained. Some background details that probably don't apply to this issue, but I moved out of the Comcast service area 6 years ago, but was able to maintain my email account(s) as long as they're in use. I was able to change my Primary password, but was locked out of making changes to the secondary accounts. I also get the message, "This account is no longer active.", but it still is. At that time, all my accounts continued to work.

In any case, TB has worked without issues for years on both my Comcast and Gmail accounts (Gmail still works fine) up until the Comcast security issue. A few weeks ago, Comcast stopped working, asking to reenter my password, but re-entering it did not work. I eventually talked to Comcast email tech support (lol, after about 20 minutes of navigating their phone system). I was told that I should DELETE my (primary) email account and then recreate it. I did that, but in that process, I lost all my message rules (but I eventually retrieved a backup version of "msgFilterRules.dat".

In that process of re-creating my account, the Authentication method was changed from "Normal Password" to "OAuth2" (same used with Gmail). With that change, I no longer get an "Enter a new password" message, to "Unable to connect" (see attached image). I also get an "Authentication failure" message, and an occasional "My IP address has been temporary blacklisted", probably of my multiple attempts to re-connect. I should note that Comcast email still works from my Android Samsung S22 email app. See my current TB Server Settings in the attached image.

Well after many fruitless hours, on a whim, I opened my old and trusty Outlook (Office) 2007 (that I've never used for email), and with their settings with the same ''Port numbers, but slightly different "Encryption" (Connection security) settings, Outlook works! The difference between Outlook is that Outlook only uses SSL, whereas TB uses SSL/TLS (no option for SSL alone).

So, herein lies the problem. I WANT to keep using TB for my Comcast accounts, but I'm locked out (NO sending or receiving). I could just use Outlook, BUT I loose all my rules (moving incoming emails to their respective folders. As expected, Outlook uses a proprietary binary rules file format (rwz) which is unreadable and uneditable. From my research, their are no filter programs or file structure descriptions for the Outlook rules file.

I can use Xfinity's (Comcast) web based email client, but again, NO RULES possible (after 20+ years of use, I have almost 200 email sources that use my primary Comcast email address). I tried over time to migrate new sources to my Gmail accounts, but not my existing ones. I fear however that this is an internal TB issue, that has no easy solution, if at all.

So, I asking you to please help me resolve this issue. It would be gratefully appreciated.

Thanks, Bill

P.S. After talking to Comcast the last time, they essentially said that they won't support TB, and it's not their problem to fix.

Hi all

I have an IMAP account which has altnamespace enabled (i.e. my folders are on the same hierarchy level as my inbox, not subfolders of it), and a server-side filter that sorts incoming mail into either one of the folders or the inbox.

When I enable message filters in TB, they seem to run only on the inbox itself, not the other folders. I can select a filter and then click "Run now" with the appropriate folder selected, and the filter works. But that of course beats the purpose of the filter (which is to delete messages based on sender address).

Is there a way to have message filters automatically run on the other folders?

Thx!

1. Often TB won't show new message, it'll list a number of new message, maybe I can actually scroll down & view a few of them, but quite often, I'll try to scroll down and can't see that new message that TB indicates exists. Or I have to click on an old message, then try again, click on another message I've already viewed then scroll down to where the new message is. This morning, tried both several times, still couldn't see the new message that TB insists is there. 2. At one time, when you opened TB, you were automatically taken to the end of all the messages in your inbox or if you fllter emails to folders, to the end of messages in that particular folder. No more, you have to scroll down to the end. Why? It's a waste of time for me to do that and as far as I know, TB places no limit on the number of emails in an inbox so . . . why was that changed? Because it was user friendly? In my search I noticed that there was one TB user who was so upset he/she/they wanted to return to v. 102. I wonder how many people, seeing the response, also have returned to a previous version. I know I'm really tired of getting additional bells & whistles i don't use, changes to what you see that don't help me at all, plus making using TB more of a hassle--see above. Please fix the above problems. If it's not fixed in the next upgrade--which I'm hesitant to install given the result of the last few upgrades that introduced the above hassles--then I'll probably go back to an older version too.

I'm trying out Thunderbird on macOS, and one annoying problem that I can't find a solution to is that the line spacing in the window for composing emails is too small. (See the attached image.)

I currently have the font set to Helvetica, which is my preferred font. Other fonts work a little bit better, but they all have this problem to some degree. I can't find any settings in Thunderbird to adjust anything about the font used when composing emails, other than the font family and size.

Is there any way to fix this?
