I have backed up the data regularly before, but in the new Windows 11 pc, I cannot find the data.

It used to be "C:\Users\Jim\AppData\Roaming\Thunderbird\Profiles\itfho9h2.default" on the old Windows PC which went bonkers. Now should be "C:\Users\Jim\AppData\Roaming\Thunderbird\Profiles\i3ls19ra.default-esr", but when looking in the "C:\Users\Jim\AppData\Roaming\" folder, Thunderbird folder is not there with the others. But that is where Thunderbird data is supposed to be according to Account Settings, Message Storage, Local Directory.

So, how do I find where the data is so that I can back it up?

Thanks.

hello,

I have been away from this laptop for about 7 months; now, when I try to access TBird, it seems to hang indefinitely [I haven't timed it but it seems like more than half an hour, maybe a lot more] displaying "xxxx@xxxxx.com: Host contacted, sending login information" in the bar at the bottom of the screen ... Every once in a long while, it jumps up and asks for my password. I give the one that relates to the "xxx" email address above and it rejects it as incorrect. I have checked that the password works to get into this account on webmail.

Can anyone help? I don't remember having this problem before. I am using TB 115.10.1 (64-bit) many thanks, filter feeder

have been trying to get you to help me for almost a year. I can neither send nor receive emails. I ask you to do something so that I can use thunderbird again. My email address is: [edited from public] @live.dk and my name is: Karen-Margrethe Hasselbalch

Hi, I've successfully downloaded and installed Firefox on my HP laptop with Windows 10 and now attempting to download and install the Thunderbird email client. On Thunderbird.net when I click the Download button, the Donation Page pops up (and I made a donation) then closed that window. I'm then on the Thank You page but there is no prompt to install, so just stuck on the Thank You page. Thunderbird is not appearing in my downloads file. Can you please help?

Can't this problem be solved, the other clients are doing well :man-shrugging:

I wanted to say thank you, but the post is in the archive. https://support.mozilla.org/en-US/questions/1197767

Thank you very much!

The year is 2025, version TB 128.6.0esr (64-bit), and your solution is working!!! This is a real problem, IMHO! I looked at the TB at lunch, there was no letter, I look at the letter in the evening and he writes to me that it arrived at lunch. It looks like I’m blind :(

When I try to send an email here is the message I get.

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.sasktel.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. I checked my outgoing SMTP settings and they are all what they are supposed to be. Port 465, Password Authentication and SSL/ Note** when I first installed Mozilla everything worked fine. Now I can not receive or send out emails. I have Kaspersky VPN and Kaspersky Internet Security

I was searching for the Local Folders in the mail folder of the Profile folder, but it wasn't there, but in TB I can see all the local folders I searched my computer and I found Local Folders folder in a desktop folder. To test I created a new folder in TB and then checked to folder in that desktop folder and it was updated. It seems to work even though its not in the profile directory. I don't know how I moved it and why it works, but I checked the properties page on each Local Folder and they all pointed at the desktop folder. How do I move them back and still have TB see them. I cut and paste one folder back, but TB was still pointing at the desktop forlder

Hello, there was a problem after reinstalling my Windows 7, it became impossible to send messages in the thunderbird application, and there was also a problem accessing the thunderbird website. I am attaching Cloudflare Ray ID: 93ea7d136f38f141.

Hello, can anyone help me prevent my Thunderbird client from switching to Variable Width font in the first line of any new draft? It has been incredibly irritating when composing mail. (Same issue has occurred when responding to emails.)

My HTML code signature only has two empty lines, coded as such prior to the “Thank you,” as seen in my sequential screenshots: <font size="4" face="Helvetica">
<font size="4" face="Helvetica">

… yet there is a third empty line that precedes both of them when I click “+ New Message” or reply to email. When I go to line 2 or 3, then return to 1, it switches to Variable Width, and the font is also much smaller.

The problem does not occur when arrowing between lines 2 and 3... only when returning to line 1. </font> </font>

I have a problem I cannot figure out what happened and how to fix it.

When I went in to email someone, I would open the New Messages. There used to be a SEND button on the top left of the New Message. But for some reason the SEND button is no longer there, and I cannot figure out how to send a message.

What can I do the get the SEND button back to the New Message so I can send the email?

After a message saying "Couldn't load XPCOM", I uninstalled and then reinstalled Mozilla Thunderbird and it's working again. Is it now safe to delete the uninstalled version from the Recycle Bin? Thank you.

Hi..On my email page inbox I have "Open in Conversation" Works fine for me when I use it.. Problem is that although the Reply in Conversation is high-lighted with a yellow star on the Inward Mail Icon when an Email arrives I can't tell which email the Reply is for..

I get Lots of Email Replies so which Email line is it?..

There is a Small icon in the left margin for a Reply or two but no more that that.. Some of my Emails have up to half a dozen Replies in Conversation..very frustrating.. Which means I have to hunt thru my Emails to find what Reply Received is for which Email.. I would like Mozilla Thunderbird to add (somehow) a high-light for the Reply in Conversation & which Email it belongs to... That would save me a lot of searching... Any idea's.. Thank-You ..

how do I remove emails from my gmail server to reduce the storage there and have them as a reference still on tbird? in general, I'd like to have my emails in all folders moved to tbird and not left in gmail

Hi,

I'm getting low disk space available messages on my Windows 10 Pro PC.

Wiztree (see attached image) is showing 128gb in my imap.gmail.com folder.

Some time ago I started to get fairly regular popups about compacting my folders, which seemed to take an eternity without seeming to achieve too much, and I noticed that every time the TB application was shut down and restarted, the Inbox would show mails starting from 9/5/2022 every time (see attachment) and then gradually start to slowly load all more recent mails. In the lower left of application, is the message "Downloading message xxx of xx,xxx in Inbox" and it slowly counts away.

Around this time I had ine excess of 40,000 messages (many with attachments) and I began deleting all the larger attachment emails, and slowly started to cull older emails to where I now have 14,000.

The disk useage appears to have worsened over the past few months.

I'm thinking I have some sort of corruption in the database??

Please advise as to best way forward.

Thanks in anticipation, Peter
