Thunderbird Community Forum

I cannot send messages from any of my accounts after migrating to Greenby. I have tried to setup their outgoing server as per their instructions but it does not work. They have a AI tool which I keep going round and round in cycles

After several years of working perfectly,For no reason, I am getting this message when trying to connect to Xfinity email server

"  Login to server mail.Comcast.net with username t_m_f@comcast.net failed."

I have set all Comcast server settings to the default. Going directly to Xfinity email works great . So it must be something wrong with Tbird. I also uninstalled & reinstalled Tbird. This is frustrating !!!!!!

When I try to forward email with attachment. I get a error message stating I dont have access for the attached file so every time I have to remove the attachment in the email and download the attachment from original email and attach to my email. Which is frustrating and time consuming process.

What I thick is there is storage path issue with my email setup.

Please assist to resolve this issue.

I realize this can be a macOS issue as the problem appeared when I upgraded to 26x but I'm hoping that maybe there's another way of allowing windows to be moved with a mouse. This issue appears only under tbird and not under any other Apple or non-Apple products.

The new child window(s) opens up in the default location(s).

The issue has survived several OS updates up to the current one. I switched from macOS 15x to 26x in around January 26.

Firefox does not really open any child windows that I could find but browsing windows work as expected.

Thunderbird causes my machine to 'hang' from time to time,

1. often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance.

2. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding"

3. I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable.

4. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

I can't send emails from my Thunderbird account. I am however receiving them. Using IMAP. All server settings appear to be correct. Error message reads " Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.stackmail.com timed out. Try again." What's going wrong?

I have followed all instructions I can find through many searches online but cannot get my outlook email to configure in Thunderbird. First, I have no option to chose OAuth2 even though I have deleted any outlook passwords, email accounts, and Thunderbird is up to date. I have received so many error messages I cant keep track. Bottom line, all my other email accounts configure find except for outlook. Any help would be appreciated Steven Pecoraro

When I try to send a message I get the following error message: An error occurred while sending mail: Outgoing server(SMTP) error. The server responded: Cannot connect to SMTP server 209.71.208.9 (209.71.208.9.25) connect error10060 How do I fix this?

Sometimes a search term will pull up many emails I need to sift though, like in the case where it's a common word, like permit. I was searching the term "permit" for building permit emails and got many unrelated emails that were more recent with permit in the email body. I am able to quickly skim and see these are unrelated but the limiting factor is only ten results per page. When I click load more, takes a few moments to load. I was unable to find any way to change this. How can it be done? Should be possible, it's doesn't affect Mozilla's processing because everything is done locally on my machine. I would much rather 100 results to load or to load indefinitely.

Additional question: on that search term, many unrelated emails came up as mentioned before. When I searched the same term in gmail in my internet browser, only relevant emails came up. Why is this? How do I improve the thunderbird search?

Please let me know if it is safe to remove the older version of Thunderbird in the Installed Apps list. I also question whether the size of the app in the list is accurate; 250 GB seems quite enormous in a 500 GB hard drive. Thanks, Hans

I have just re-started my problem when this system crashes again. For 3 weeks I have sent reports of sites being crashed. The has not been any changes. It happens when on web site and also when using E-mail. HELP!
