I'm Using Thunderbird version 148.0.1 (32-bit) on Windows 10 Pro I currently have 2 email accounts in Thunderbird...a Gmail account and a private account linked to my own webpage account. Both these accounts are working very well and I encountered no problems when I originally set them up some time ago....... However.. I am trying to add an additional email account. a Live .co.uk account I enter my Full Name and email address "xxxx@live.co.uk" as requested... I enter my password for this account and in my "Your Login" details ( the characters "xxxx" before the @ in my email address) I then select "Continue"........... Response : "looking up configuration...." Then.... Authentication failed. Please check the username and password...Exchange auth error I know I have entered the correct username and password for this account... and the account works fine on my mobile phone email app. using the same username and password..... No matter how I try, I am unable to set up this existing Live mail account so that I can access it in Thunderbird...... along with my other email accounts in Thunderbird, which are working OK.... Any suggestions as to how to fix this annoying problem, would be really appreciated......... Thank you

The arrow is tiny and hard for me to see (as well as the vertical bar for selecting text). In other programs it is quite large. I have the LXQt cursor size set to 60. How can I increase the size for TB? How can I make it invert color so as to have good contrast always?

Originally I installed LINUX MINT Cinnamon 22.3 and all worked extremely well this was on JAN 5 2026, Installed a series of updates and everything was fine. Installed the last update and it changed everything from the font size and type of font to startup and now I have only use of one (1) display monitor whereas both were working without an issue before. Both are working fine and and are plug in properly and have power. I can not seen to add a second monitor. Please advise, thanks

I’ve tried all versions of Thunderbird on my 2020 M1 Mac, and even though I log in correctly, it doesn’t load emails from my account. I used to use Thunderbird normally because I needed it, but I haven’t used it for two months, and now I see that it doesn’t work when I try to connect to my email. It connects to my email normally, but the problem is that when I click on “Inbox,” there's nothing there, and when I click “Fetch Mail” to try loading it again, a message pops up at the bottom saying everything is fine, but in the end, I still don't have those emails. What kind of error is this?

Hi I am having problems signing into or adding my tpg account email address through both outlook and thunderbird. My address and passwords are correct and I have used the settings in both email programs as listed by the messaging company. The error message I am getting is that on thunder bird it cannot find the settings for my emaill account and on outlook it cant find the settings. I have had ongoing issues with my tpg account, this one is a pop3, since the messaging co took over the emails when tpg moved them to there. Issues are that i get very sporadic emails ie one week working the next nothing for long periods of time. I can successfully add gmail accounts to thunderbird and outlook without problems but the tpg one is my issue. I can get tpg emails through the gmail app on my phone with pop 3 settings but nothing on thunderbird. I have contacted the messaging co for help but other than settings they cannot help and suggested coming to thunderbird for help. I prefer to use thunderbird as my email program to have everything on one would be great again. Can anyone offer advice or assistance I would greatfully appreciate it

Hello

i am struggling with TB as it always uses the default email of a server account.

Instead, i would like to use different accounts based on the recipients

I could not find an extension with this behavior.

For example, I would like all email exchanged (sent & received) to a domain ( @thatcompany.com ) to use a given account alias (myalias.email@proton.me)

Thanks for all assistance

I have been using Thunderbird for a fairly long time and have several email accounts in it. Today, I noticed that one of my accounts seems to be filtering the messages for one type of message. When I login to the email account directly, I see all of the messages. I don't have any filters set - none of the filter buttons are on, there is no filter in the filter text box and there are no filters in Tools->Message Filters.

I am trying to set up Thunderbird. There are questions I don't understand pertaining to such phrases as IPOP and whether I am using a server or not . I am using Linux mint.

Thunderbird version 148.0.1 will not send outbound emails since updated to OAuth2. Error message is Unable to Authentic Outgoing server (SMTP) Email account will allow inbound mail , but will not send mail. Have worked through all published troubleshooting steps. Extremely frustrating!

Please help! I have not received emails on thunderbird for a week. I have had to go through my web browser. I received messages that thunderbird is temporarily unavailable. What is the problem? How can I resolve this issue? Thank you very much!!
