Thunderbird Community Forum

I have been using TBird for many years, but only for email. I have about 15,000 emails and an 18 GB profile. If I start using TB for calendar events and tasks, will that substantially increase the profile size and does that become an unwieldy folder to maintain in terms of errors occurring with time, and in terms of transferring it to a second PC?

Make it easy to have Thunderbird store the latest messages on top in each folder rather than on the bottom. Sort function does nothing to fix this.

Make it easily to keep ALL messages unthreaded in all folders!

If I unthread them they always go back to threade after I login again.

128.1.0esr (32-bit) Release notes

Provide an option in global settings, to use a SINGLE, MASTER "MsgFilterRules.dat" file that applies to ALL accounts vs one for each account.

My self - and MANY other users - (based upon forums) have been attempting to create a single, consolitated .dat file, then paste it into each accounts Profile sub-directory. One issue is that periodically a user must repeat the process due to additional filters created over time, but only in its relative account.

This am, TB informed me I needed to compact. I clicked on ok, next moment all emails in my inbox have disappeared. I eventually found them in a trash folder. How do I move all of them back to my inbox?

I did not set up a password to view my passwords now I can't get out my passwords. I'm the only one who has access to the computer so there is no need for this "added security", more added annoyance. I've never had to have a password before to look up a password on one of my accounts but now I'm stuck with this function turned on. I think they must have forced it on me in a resent update because I just looked at my passwords last week. Yes, I know there is a thing to reset my passwords in Thunderbird and hopefully let me turn this silly requirement off. But I've tried that and it did nothing at all.

I just downloaded Thunderbird onto a new computer and can't get it to log into my Yahoo Mail. I recall in the past that I had to set Authentication to Oauth 2. There is no option for that in current download of Thunderbird. How do I get in?

Messages came: 1) Unable to write messages to mailbox

                              2) Processing your a/c, please be patient

I would need someone on the phone to walk me through any changes, as am not very computer savy. Darlene

I recently updated my Thunderbird client to v115.0b6 (on a 2012 Macbook Pro with Mac OS 10.14), and as so many apps nowadays, it has become worse instead of better: - There is a large margin on the left side of the subject column in the email list which wastes a lot of space. How can I hide it? - Performance is worse: The update of the mailing list and the spam filtering is significantly slower than before. Often takes a second for 2-3 items. Why should an update with basically the same functionality ever become slower? - The issue that external images are never shown to me even after I have allowed external contents to be shown is still not solved.

As far as I remember, going back to a stable (non-beta) and more performant version (where the last issue shouldn't exist) is complicated due to database migration. Probably someone can help me accomplish this anyway.

Emails are being deleted immediately on download and nowhere to be found. Adaptive junk mail controls or off, unabled. I want all emails including 'junk'. Why is this happening? How can I correct this?

Below, and attached, is the error that is displayed each time an email is sent from thunderbird on a single PC only that is on a network. The error is for a malformed email that has a "." after the .com

Send Message Error ! Sending of the message failed. An error occurred while sending mail. The mail server responded: <removed@removed.com.>: domain missing or malformed sender already given. Please verify that your email address is correct in your account settings and try again.

Resolutions attempted: -The malformed email has been removed from the local address book and the error persists -Thunderbird updated to latest version

Any advice or solutions is appreciated. Thanks!

'bold text'bold textOn 6/24, Juno Security <security@support.juno.com> sent me an email that Thunderbird downloaded that my account had been compromised, & I needed to reset my password. I chanced my password in Juno & put that same password into Thunderbird [I think] Since then I have needed to use that new password to open the Thunderbird program, but Thunderbird won't download email from my Juno popmail to Thunderbird. Thanks for your help.

Hi guys,

I have a bug noted in Thunderbird for OSX:

Thunderbird for OSX always send messages to Sent Folder, even if not checked to do so.

I use BCC to send copies of my emails to Inbox, but everytime I send some email a copy is placed in Sent Folder even if I already set to not put a copy there. It seams that uncheck the checkbox to don't do so have any effect.

My Thunderbird just upgraded me from 115 to 128.1.0esr. After the upgrade I can no longer send emails. I receive emails but when I try to send them, after pressing the send button, nothing happens - no popup telling me that Thunderbird is trying to send the email or anything else. If I close the send box, it saves the email to drafts. - I have not changed any of the outgoing server details and all was working fine with the previous version - 115.??? (don;t remember the service release but I think it could have been 9). Any help to get this resolved would be appreciated.

Thunderbird fails to opn properly and I get message "Unable to open folder mailbox ... because it is in use by another process. Please wait..." Waiting never ends. It is trying to load my default in box. If I try clicking on the Loading message £I get Thunderbird is not respondinng ,,..."

The Quick Filter is extremely slow on version 128.1.0esr (and also on 128.0.1). 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). When will this bug fix show up in the release version? Or how do I put in a patch? Thunderbird is almost useless for me with this problem. Here is the bug report thread: https://bugzilla.mozilla.org/show_bug.cgi?id=1908761

Thanks for you help.

Asked this question before but never received a response.

When someone sends me an email from their gmail account, thunderbird dopes not download it from the server. I use gmx.com for my email. All other emails sent to me are downloaded by thunderbird but not ones sent from gmail accounts. It is not a problem with gmail because if I use the web access, the email is on the server but is not downloaded by thunderbird. I have checked the filters in thunderbird, there is no reference to gmail.

The odd thing is that I have a second email account, also on gmx and thuderbird does correctly download the emails sent from gmail accounts. Any idea how I can solve this problem?

Sometimes when I save an email in my inbox to a subfolder it doesn't appear in the subfolder but when I search for that email search finds it in that folder. Why doesn't it appear in the list of emails in that folder?
