Thunderbird Support Forum

Like many, I'm getting Authentication error using gmail. I had no problems on my old computer under Windows10. When moving to a new computer with Windows11, my main gmail did install. However, 2 other emails, I also need, will not install without this error. I'm using McAfee LiveSafe antivirus on the new computer. If I can't solve this, I'll no longer be able to use Thunderbird (which I like!).

Today my 102.0.1 has disappeared. TB has worked for me for decades including now on 102.0.1 which is the latest version. I've downloaded 102.0.1 again but still doesn't show up.

Been using TB for ages - love it - however it has recently stopped receiving emails - what is the cure? Reinstall? New update?

About your message below regarding 'Email me when someone answers the thread' - if the problem is that I am NOT receiving emails? Send a text?

suddenly Thunderbird email stopped working. I keep getting a request to input and change my password and have done that several time. I also have gone through all the steps to ensure all the info was correct and connected properly. My email works fine when I login through the internet. Passwords are correct, connection info is correct. My emails work fine on my phone. I have uninstalled the program but it had no effect. I am using version: 102.0.2 (64-bit)

Does Firefox save a backup copy of things like address book and archives? It so, where and what are the file names? How do I prevent future updates from removing important data? HELP!

My version of Thunderbird is 102.0.3(64-bit). It will not update. i keep getting a message that it is not able to download the update and need to download a new version for the update. Can any one help me. Thanks

Hi Thunderbird updated itself to 102.1(and now 102.1.1) and it lost 2 of my mailboxes or at least the inboxes. I have tried repair folder in the preferences for each inbox. The inboxes are greyed out. The location in the preferences, imap://driver_al%40*********@pcluster02.stablehost.com/INBOX, takes me now where or at least I can not find it. It is does not even seem like it is checking for new mail in those boxes.

I have a total of 11 mailboxes of mixed imap and pop. Only 2 seem to be effected both imap. I have looked in the profiles folder but do not seem to find them there as the folder names do not match the mailbox names..

With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

I want to talk with a Thunderbird agent for help. I'm not sure if this is the right way to communicate. Thank you for responding. I finally did get the help I needed when I returned home from travelling. A local business uses Thunderbird on a Mac like me. "Ionos", which hosts my website and web mail that goes to Thunderbird helped me on line to put in changes they require but that did not work for me. And I lost all my email except for the last week. Also mail wasn't coming into Thunderbird. It turns out my Avast had something to do with the muck up. It took 2 hrs. to solve the problem. My husband Uri Cogan passed on last Nov. He set me up with Thunderbird and took care of everything related to my computer. He was a volunteer helping here. Without him I am slowly learning what I can. I am finding out that most people don't really know anything outside their lane and any friend I asked was as clued out as I am.

I was told to reboot my system to complete a Thunderbird update.

After the system came up, my main email account wouldn't display. It was there when I went into account setting but wouldn't show. After closing an opening Tbird several times it showed up. now none pf my filters are running. In some cases it says the folder doesn't exist when it does! Most of the rules are missing actions!

What's up guys???

I have purchased the Owl addon so that I can use two Microsoft 365 email addresses in Thunderbird, I have set them both up and they appear in the side panel with my other email addresses but only one of them will send or receive emails. Please could someone supply up to date instructions on how to set two exchange accounts up. Thank you

Message: Login to server outlook.office365.com with username xxxxxxx@xxxxxxx.com (my work email account set up thru GoDaddy) failed.

This is not my primary method for using my work email (Gmail's webmail interface is and, yes, still works fine). But every once in a while, I want to use the features of TBird that aren't possible with Gmail. So, I tried running TBird last weekend and got that message. So, first I tried signing in thru GoDaddy (O365 webmail) and used my existing password, and of course it worked fine. I then tried deleting the TBird account and adding it as new. TBird recognizes O365 accounts and I used those settings but, again, the password was rejected. So I went semi-nuclear and uninstalled TBird then reinstalled it. NO DIFFERENCE.

WHY is TBird rejecting my valid password - ESPECIALLY when it was working before?

Please pardon the raised voice all caps here and there - I'm really frustrated and don't understand what broke or how it broke and I can't fix it.

HELP!

Until yesterday I could click on 'Inbox' and it would shows all emails from all 3 accounts I have set up. There was an update yesterday (102 1.2) Now although I can go to each email account individually, when I click on 'Inbox' it only shows emails for one account.

It also seems that search is also not functioning across accounts.

What must I do in order to enable address book address information. Now when I try to change address information it is as though my keyboard as been disconnected. thanks

Hello! I was wondering if you guys could help me get set up on Thunderbird. I'm having some trouble getting logged in with the "Set Up Your Existing Email Address" section. I'm certain I'm typing in the right login info but it says it is "Unable to login at server.

There is a context menu entry that enables message fetching for individual folders and an about:config setting for doing it for all folders. There is some speculation in a different question that this is necessary to avoid overloading servers.

Is this true and still appropriate? How can I as a user tell what I can set this to?

From a UX point of view it would definitely be better to just check all folders for new mail.

Today Thunderbird auto updated to 102.2.0 (32-bit) on Win7 64bit, have been using Thunderbird for many years.

When you search in the email for something theresults are show as usual and you might have 100 hits Then normal if you click the "Show result as list" you will have a list with..... 100 item where it's fast to pick the one you need.

After today update the "Show results as list" are empty except if the a mail in from today.

Is this kind of a new settings I will need to tweek to see all the results as list or is it a bug?

Please advise

How often does 102.0 update? It appears to update every ten seconds by my estimation because every time I launch it updates before loading. I can close it and open it seconds later and it pauses to update again?

Is this some bug that it keeps updating no matter how many times a day I may open or close the program?

Should it just check and remain silent if there is no update?

I am going to turn off updates until I know why it does this. Never had this issue with prior versions.

I am unable to login to my Thunderbird email account. I was told by my Skybest support team that they would have you call me with the PASSWORD that will allow me to log in. My phone number is 336-200-2068. Thank you!

TalkTalk are updating their email process shortly, will Thunderbird cope?
