Thunderbird Support Forum

The last auto upgrade included a calendar function, which I switched off as I thought this was causing the problem. But now after all the messages have downloaded, I get the usual pop-up box in the bottom right of the screen telling me I have received x messages but it only half fades in and the whole PC jams. CTR-ALT-DEL does not work and I can't switch to a different window or even click on anything in the Thunderbird screen. The only thing that I can do is hard reboot the PC and switch off the router, which allows me to start up Thunderbird without anything downloading. I am using Windows 7 and Avast as my AV. Any help would be gratefully appreciated.

Since recent updates (I'm on 91.2.1 32 bit) the gesture-scrolling (two finger drag) with my Windows 10 laptop's touchpad is much faster than before, and I'm finding it too fast to control. If this is an intentional change, can it be toggled off?

I temporarily logged into customer email account in order to download the mail in it and transfer it to their email at a different webhost.

And in fact subsequent to that the email account was closed at the prior host by its owner. They actually deleted the email account at the old host "Bluehost" which admittedly is a garbage host and hence why they moved.

So I removed it from my email accounts in my Thunderbird.

For some reason since then I have been receiving constant popups from Thunderbird "Authentication Required - Mozilla Thunderbird - https://box2164.bluehost.com:2080 is requesting your username and password. The site says: “Horde DAV Server”"

and the username field has the email address in it. The password field is blank.

And I checked the outgoing mail servers in Thunderbird to confirm I have no connection to the email acct stored in Thunderbird.

Any thoughts on how to alleviate this issue?

Thank you all for your time and attention to this request.

Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

I have Thunderbird installed on two computers.

On one of the computers, emails being held in my inbox are being automatically removed after two weeks (this is not a desirable action, I am loosing important emails), but on the other computer that is configured exactly the same, emails remain in the inbox indefinitely (which is desired).

Both computers are POP and both configured to run the same email account and appear to have all of the same configurations and settings. I saw someone had posted the same problem a while ago and the reply indicated it may be that the ISP or email provider has their settings set to delete emails as per the two week window, but as I can assure you this is not the case, it is a configuration issue with one of the Thunderbird installations, otherwise both of my computers would be deleting the emails while that is not the case.

Thanks,

I can't send out any emails all of a sudden. I'm getting the following error message: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtpauth.earthlink.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

Please advise.

Good day, I am using Thunderbird with my Office 365 e-mail account. I like pretty much the appearance of Thunderbird, as it is not so crowded as Outlook. Unfortunately very frequently it is "Not responding" and the screen freeze for few seconds. Should wait untill returns to normal condition itself, to continue my job. I did not found any topics into help about that problem and any solutions. With Outlook I do not have the problem described above, but prefer to use Thunderbird. Kindly ask you for any advices, if available. Many thanks in advance!

Thunderbird asked to compact folders saying it would save hundreds of MBs of disk space, I accidently clicked "compact now" instead of just ignoring it as I usually do. As a result, Thunderbird deleted all mail on my Inbox folder - after restarting Thunderbird, my inbox was empty, I also checked the mail folder on my file explorer and the "Inbox" file (no extension) was just a few KBs, whereas previously to Thunderbird deleting it was several MBs. There were no errors reported during the "compact" process.

I don't think I can recover the mail that Thunderbird deleted because the mail server does not seem to keep mail older than 12 months. One of the reasons I used Thunderbird was to be able to keep a local copy of older emails.

The pop-up I received was the one shown in this article by Mozilla: https://support.mozilla.org/en-US/kb/compacting-folders

The article explicitly says "compact" does not delete mail, but then explains that it actually does (by not moving mail "moved or marked as deleted" to the a new file, and deleting the old file). I had no such "marked as deleted" mail. It was just plain read mail on my Inbox folder.

This is an Office 365 POP account. Thunderbird's retention policy for the Inbox folder was to use my (Thunderbird) account's policy, which was to never delete any mail. Alas, when I hit "compact now", Thunderbird deleted all my mail. I was running Thunderbird 91.6.1 on Windows 10.

I tried making a backup of all Thunderbird related folders and deleting the "popstate" file to download all mail from the server again. Mail got downloaded, but not all - as I mentioned, the mail server only returns 12 month worth of email, whereas I had years of mail stored locally. I don't see any way of recovering it... Why would Thunderbird just delete all mail calling it "compact"? Makes no sense...

Outgoing mail stalls. The blue line goes across from left to far right and then stops. A "message sent" does not appear. I have waited for 30 minutes and the stall persists, even with a short test message. I turned off my antivirus (Bitdefender) and firewall. Incoming mail is fine.

I have another computer that works well for both in and out mail. Both computers use the same ISP (Netfirms) and have identical outgoing server settings, except for the email address.

Your help is greatly appreciated!

I have over 200,000 emails on a gmail account I'm hoping to sync with Thunderbird. My goal is to have them all downloaded onto a local server on my computer so I can refer to them all offline. I've been periodically pressings "get messages" which used to download messages 1000 at a time (I'm not sure why it doesn't continually sync with my inbox!) Though, sometimes it would download 2-3 at a time which was frustrating and fairly futile. Now, it's stopped downloading entirely. How do I keep syncing my inbox?

I just downloaded Thunderbird on my new computer (HATE Windows Mail). I use gmail for my email. My mail DOES get sent out, but DOES NOT save to my SENT ITEMS folder. It starts the process, but cannot finish. It seems to get bogged down and can't complete.. How can I fix this?

I have updated to Thunderbird 38.1 running with XP Pro. Thunderbird fails/crashes every time I switch users. We have 3 account profiles and failures occur on all 3 profiles.

Crash reports cannot be sent to Mozilla as errors in transmission occur.

While Thunderbird is working it is good but the constant failures are frustrating.

I am using Thunderbird version 31.7.0 and it keeps randomly crashing when usually when I try to send an e-mail. The e-mail appears to go out, but it is not copied to my send folder. I can keep it working is I use safe mode.

My Crash links are: https://crash-stats.mozilla.com/report/index/9e388085-aa3d-454c-bf55-924102150612 https://crash-stats.mozilla.com/report/index/2613f4fa-89d4-49c3-92ad-4f3292150612 https://crash-stats.mozilla.com/report/index/a5f726e5-8f62-40a9-9087-4bab92150610

Hopefully someone has an idea how to fix this. It appears every crash is for the same reason.

Thank you for your help.

Hi. A few weeks ago I had a Thunderbird-is-already-running type message, and couldn't launch Thunderbird. I consulted these forums, and (as suggested) deleted the parentlock file. That got me into Thunderbird, but all Local Folders were missing from my Local Folders list.

I consulted these forums, and (as suggested) deleted .msf files from the Local Folders folder (with Thunderbird closed). I restarted. These files did not regenerated, and the Local Folders are still inaccessible.

I can use the Thunderbird client to search for messages in the Local Folders. I can see these messages, but they cannot be opened.

Each individual Local Folder file seems to be there in the Local Folders folder. I appear to have only one profile.

I would really appreciate your help in reinstating the "missing" Local Folders, which contain (guess what) important e-mails. I've no technical expertise (any longer), so would need really clear instructions to follow.

Big thanks.

I can not get thunderbird to bring over email for 6 days now I get the following error everytime. (Sending of password for user .........................@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later.) I have tried creating a new password on the server account and restarting thunderbird with the new password . Did not help. Any Suggestions?

Dear community,

in the past, I have noticed that a few e-mails - but not all - are displayed incorrectly as plain text instead of the usual HTML-text. This means that there is no formatting involved, e.g. the font art is not correct. As it seems, the issue occurs when the standard formatting options of e-mails are used by the senders. So if nothing is changed like the font size or colour. If I look at the e-mail on different e-mail programs, everything is alright. I have already ensured that the option View > Message Body As > Original HTML is enabled.

Thanks in advance for your advice. batengo

Thunderbird keeps asking me to compact folders, c.f. the attached screenshot. Meanwhile, I also checked the profile files under AppData\Roaming\Thunderbird\Profiles, the whole folder of the profile files has only 24.2 MB (25,477,204 bytes).

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.

Up until March 23 I was able to send Bcc to several people. Yesterday I tried to send Bcc and I get the message "Sending of the message failed.

The message could not be sent using Outgoing server (SMTP) outbound.att.net for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again." I have checked my outgoing settings and nothing has changed. Even just trying to send to one person with Bcc doesn't work. The mail will go if I use the To: I have two Thunderbird mail accounts and they both give me the same message when sending Bcc. I use Yahoo mail. sbcglobal.net. I have tried deleting the password and when I tried to send the mail it asked for my password. After submitting it I still have the same problem. I even tried changing the SMTP settings. No luck there. I tried the trouble shooting mode and that didn't work. I've tried searching for a solution but didn't have any luck. I'm hoping to get some help on the support site. Thanks for any help.
