Each time I open TBird, I get a message at the bottom left of the screen telling me that TBird has deleted X number of messages. I do not want TBird to ever delete any messages. How do I turn this automatic delete function off?

Does the Date field in Filters accept relative dates? I get a daily newsletter; I don't want to keep more than one. If I set it to run periodically with Date: set to "today," will it delete any mail older than today?

Does Thunderbird have disc storage space limit and if so how do I know what my limit is and how much is used? When I just sent an email, a popup said it could not be saved to the local sent folder because maybe I reached my storage limit. But I cannot find anywhere that shows me what my storage limit is or how much I have used. I appreciate any help you can offer, Thank you.

Trying to send 3 different emails. Hit send and get: 1) Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. 2) Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. 3) Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. How can I get these problems fixed?

I've used Thunderbird for years. computer crashed and I'm trying to install Thunderbird on my new PC. Thunderbird cannot find account. I've checked with my provider several times and all settings are correct. Any ideas? I've also downloaded installed and uninstalled 5 times today with the same result.

For the second time today, I lost the entire body of a rather detailed email I was composing for two different glitches. When I started to reconstruct the first I was hitting cntl-S frequently. I relaxed a little for the second and was about to save, but I got a message about the attachment from my drive that I was forwarding, and the entire body was again lost.

From the posts I've read, it appears I'm not alone. Unclear what triggers the saving of a draft, but is there a way to increase the frequency? Between the two I lost today, I wasted over an hour and lost some of the original thinking.

I searched the setting help, but didn't find anything.

Thanks! Bob

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

Hello,

I'm looking to customize the colour of the message header row (the part highlighted in red; with a black background as shown in the screenshot) to #202020, to match the rest of the elements of the view. While I've successfully managed to customize other elements (code below), I need help with identifying what to specify for the message header row.

.tree-table { background-color: #202020 !important; }

treechildren { background-color: #202020 !important; }

#messagePane { background-color: #202020 !important; }

#messageHeader { background-color: #202020 !important; }

#msgHeaderView { background-color: #202020 !important; }

Thanks and cheers.

I want to auto delete all msgs from a specific sender. I want to create a filter which will delete them so I won't see them at all (auto deleted). I tried to create one but could only move the messages frm the sender to the spam folder. But I don't even want to see them there. I want them gone automatically.

How do I do this?

I would like to setup Thunderbird as my email client.My email service is provided by Godaddy with an Outlook account. When I am at the incoming server settings, it has my domain name, not smtp.office365.com which I tried with both authentication options (below) and with my domain name, the protocol was IMAP. I changed the port from 143 to 993. I changed security from Autodetect to SSL/TLS. For authentication, there was not an OAuth2 option, I tried Autodetect and Normal password, neither worked. And I used my domain email password. with using my domain name, it came back with an error an suffixed my domain name with :110. It stated that this was not the correct domain and there was a security issue. It is not clear how I should progress.

Cannot send email on Thunderbird suddenly. This happened after Thunderbird update on 7/16/26 or 7/17/2026. Also could not receive email on Thunderbird for two days after the update but that issue suddenly resolved itself after 2 days . Have tried to change the port but that has not helped. I use rcn.com We could not send or receive there either when I went on the server. Now rcn is working again on the server but cannot send using Thunderbird account.
