The ability to change font size is disabled. I lost my User profile on my PC, and I am starting from scratch with all settings. My custom folders are still there, but I have had to recreate message filter rules, and I can't get the font large enough to read.

Note: When I click on the image I provide below, it makes it look like my font size is huge. It is not.

Last night I used my Computer and checked for New Emails, before Powering Down. This morning I Powered Up and went to see if an Email I am waiting for has arrived - but Thunderbird is treating me like a Brand New User and asking me to Create Passwords etc. When I finally get to something that looks a TINY BIT like my normal screen, ALL of my Messages and Folders have DISAPPEARED. The last time I used THUNDERBIRD (about 9 hours ago) I just looked for New Messages, and didn't try to make Any Changes, Updates, Archives, Migrations or Imports. Why is Thunderbird treating me like a Brand New User and asking me to Set Up an Account ? How do I retrieve my Emails (both Sent and Received).

I am currently on Thunderbird v115.5.0. Ever since v115 came out I am unable to make my Inbox stay unthreaded. I set View / Sort By / Unthreaded and it works for a while, but periodically when I delete a message, move a message, or a new message comes in the Inbox reverts to Threaded view. This is absolutely maddening, as I have to repeat this many times each day. Can anyone tell me how to make Unthreaded view stick on my Inbox? I'd like to stick with Thunderbird, as I've been using for almost 20 years, but I simply cannot continue to waste so much time on it.

I have two separate Thunderbird email accounts, one which shows Local Folders in the left folder pane and one doesn't. When I select "Hide Local Folders" on the account that doesn't show that folder name, all folders, Inbox, Sent, Junk etc disappear from view. I need to change these two accounts prom Pop3 to Imap but keep the Local Folders for filing read emails but am concerned that when I delete the Pop account I will also lose all my previously saved emails. It appears that on one account all of the folders are acting as Local Folders although the top header is my email address and not "Local Folders"

Any help would be appreciated. Thanks

I am running Thunderbird 115.5.0 (64-bit) on Ubuntu 22.04.

I have two accounts with email MS - one with Hotmail, and the other with Outlook.

Both continue to receive emails without issue.

Recently, neither can send emails - having been able to send emails for years.

They had different SMTP servers, so I checked to see if I was using the correct server, and both appear as being correct.

I tried adding one account (again) to ensure TB would select the correct server, ... and it still cannot send emails, but still receives emails.

I have tried both with oAuth for the password, but that has stopped working.

I can find nothing online, and feel like I have exhausted the internet for solutions, so if anyone can help, it would be most appreciated, as I am sure others will be as frustrated.

Many thanks,

I'm having a lot of trouble setting up a functioning second e-mail account in Thunderbird. I've tried numerous times and it either doesn't show up or if it does, it won't receive or send. I wonder if part of the problem is the settings provided by my ISP. Thunderbird fills them in automatically, but they're not the ones my ISP wants. Both the server name and the ports are incorrect. I try to change them manually but then the 'continue' button is greyed out and I'm stuck. Using the ones Thunderbird wants doesn't work, I can't send or receive. I need it to be a POP3 account, my ISP gives us very limited server space.

When I set up my initial e-mail account the automatic settings were correct to what my ISP wanted, so there wasn't a problem. Any help would be appreciated.

An email will be sent with an attachment. If another participant replies to it, the original email disappears, but then appears in the chat history of the reply, but the attachment no longer appears. It still exists on the server. How can I prevent the attachment from disappearing?

If I copy paste text from thunderbird the result is text with double line endings (CRLF, CRLF) in the texteditor (notepad++ on windows) Is it possible to configure thunderbird to only have one CRLF per line?

Ever since upgrading to Thunderbird 115 forwarding email does not work consistently.

I get this error very often

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Timeout - closing connection.

I have reinstalled Thunderbird on a computer which was experiencing a Microsoft Windows 11 problem. My local technicians reverted my computer to Windows 10, for several reasons. Suddenly, I can no longer see the attachments in emails that I know have attachments. How to fix this?

I have supported Mozilla/Thunderbird since it began its existence, but if this problem persists, I will have to give up on it. If anybody can help, please help! mnylan@berkeley.edu

Thunderbird fails to access comcast.net email accounts after years of working correctly. Version 115.10.1. I have tried changing the password many times after talking to Comcast support. The best they can do is suggest I contact you.

linux mint cinnamon victoria, thunderbird 115.5, email provider runbox.com, is there a simple way to toggle b/w light and dark themes please? Thank you....b3

I've been using TB for years and years but this is the end. It was originally a nice alternative to Outlook Express with a small footprint but now it's decided that half my client list is spam. I have literally lost business because emails keep going into spam despite me marking them over and over and over as "not junk".

this is absolute BULLSHIT.

Hello Smarter People:

I am running TB 115.9.0 on macOS 12.7.1 (Monterey). This is the last OS release that my hardware will support.

I have spent a lifetime in software, so I will do my best to present the problem cogently. Perhaps it will save you some time.

I am having real problems understanding and deploying filters. I have four email accounts, which makes it a bit more complex.

I cannot detect whether filters are to be applied to EACH INBOX of my four email accounts, or if filters are GLOBAL to any given profile.

I THINK from my observations that both are true. You may define filters for individual email accounts, but if you to to Tools/Message Filters, all defined filters are shown.

No matter what I try, my filters don't achieve the desired result of automatically filtering mails into separate sub-folders. I have to drag each email manually, which can be a big job sometimes. Filters used to work, and I USED to think I understood them.

So what is the execution flow? Does mail first flow to the inbox of each individual email account and is filtered THERE, or is it all automatically sent to the Inbox on Local Folders and is filtered THERE?

I highlighted an individual email account, and went to Tools/Message Filters, and the filters there can be different from other filters that I have defined.

For example, in each of four email accounts, I may define two or more filters, BUT the last one in the order is called "Match All" which is defined to move ALL mail in that account to the Inbox on Local Folders. All incoming mail does indeed end up in the Inbox, but no filtering appears to be done.

Then I figured that filters must be global to a Profile, and defined my filters to Local Folders. Again, no joy.

I have read all the web pages having to do with filters and I THINK I'm defining them properly (I could hardly get them wrong - as clear as the instructions are). But there is no discussion of the SCOPE of filters.

I'm both confused and stuck, folks. I would appreciate some help from smarter people.
