Using TBird 115.10.1 64-bit on Windows 11. For ease of reading text in mail I am composing, I would like to select a large font size. In Settings | Fonts I chose Arial 18; but for some reason I get a small monospaced font whenever I start a new message. I can enlarge it with Ctrl-Plus, but it reverts to its old ways for the next new message. How can I make the change stick?

I get the pop up that includes Add Security Exception

 You are about to override how Thunderbird identifies this site.

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help

We had a storm and now email doesn't work. We are a business and have to have email. I've went in and changed the Mozilla password and when go back to email it won't accept it. Emails aren't coming through. Can't sign in. What do I do?

When I launched Thunderbird today, it would not connect to one mailserver: imap.mailfence.com. At the same time, Thunderbird said to restart to update to 115.2.2. After updating, it still refuses to connect. There is nothing wrong with Mailfence and I do not find anything wrong with the configuration settings in Thunderbird. I even tried to set up my Mailfence email account again but it failed because it could not connect. Ideas? Thank you.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

So... just upgraded to 115.12.2, and I'm seeing that the columns have been removed -- and I don't see a way to re-enable them!

So on the main view, we now have a line.... from address with subject below, and then to the far right, the date/time.

Is there no longer a view with columns that we could more easily see, sort, move, etc?!

Example of new view is attached.

I would like to know how I may transport Thunderbird from an old computer to a new without losing data. The old computer still is working. I do not have gmail, though I am considering going over to it.

Note: For some reason, I cannot check the box below, requesting that I receive an email when someone answers the thread. Please email me when someone answers the thread.

Dear

Subject to the following mail addresses: gunter.peeters@scarlet.be

We keep getting the following message when sending emails. An error occurred while sending email. The mail server replied: ip 213.49.30.104 blocked for relaying spam http://www.scarlet.be/pm/?e=f53&s=r&p=213.49.30.104. Please check if your email address is set correctly in your account settings and try again.

We are able to receive emails.

Is it possible to check this out?

Thanks in advance!

Kind regards Gunter Peeters

When I wanted to add a new subfolder to an existing folder, I think I used to right click on the folder under which I wanted to create a new subfolder. A menu would pop up with a line about adding a new subfolder. Now that option no longer appears. What happened, and how can I fix this, or how do I add a subfolder now?

Hi There,

After installing the new thunderbird release 15.12.2, i started getting alot of duplicates. i was messing around in the thunderbird layout etc There was a report about a damaged mailbox, but not the inbox. i think i was behind on compacting. Then i realized most of inbox was gone !

i tried the repair suggested in Thunderbird properties on the message summary index file .msf when i first noticed problem, i made copies both inbox and .msf currently:

Inbox itself is ~2Gb, but  Inbox.msf file size is 0 

i have copy of the Inbox, but copy of Inbox.msf is gone...

i reinstalled the latest thunderbird. but didn't help.

I took the advice of @Toad-Hall and uninstalled the flatpak version of thunderbird, then installed the version available as an rpm via dnf/yum and that worked. Life is good.

i'm running windows on a bootcamped macbook pro, windows 10 home. did i install correct version ? any other ideas ?

i have used thunderbird for many years and appreciate you'all for keeping it going !

thanks, Kathy
