Hello I use Thunderbird on Android before, and now how can I synchronize data on Thunderbird for Windows?

BTW, the reason why I need to do this is, recently I found the Android terminal just did not show new mails even if I refresh it manually. I also need this help though.

I attached a 9 mb html file to an email and sent it. In sending it was broken up into 10 different emails.. In receiving it, I found 10 emails and don't know what to do with them. I selected all 10, and there appeared a window with the word "archive" . Which I clicked and now all 10 email are in a subfolder named Archives.. I still don't know what to do with them in order to join them together into the original readable file.

Would appreciate some suggestions...

I newly installed Thunderbird 148 on a Windows 11 laptop (after uninstalling a previous installation under a different user). I connected to a Yahoo Mail account and downloaded all the emails from the Yahoo inbox.

Emails with attachments (.pdf and .docx) visible online in Yahoo Mail do not include these attachments when downloaded to Thunderbird.

Since the 26th of Feb. my thunderbird stopped downloading emails from any of my GMail accounts. I've accessed the email and i have a bunch of new emails there but for some reason they are not transferred to thunderbird anymore. I'm think i've installed a new thunderbird version around that time but im not really sure if that was the cause.

Also, no error message appears. it just says no new emails.

Already cleared the login details and logged again, still same issue. I'm using pop connection.

I was using MS outlook and recently I could not connect. Apparently ATT made a change so that instead of a password you need a Secure email Key. Since I needed to make a change I thought I'd try Thunderbird mail, but I still need the KEY. After a number of efforts with the ATT AI and human support people I could not find where the Key is entered on ATT. Now I know this forum is about Thunderbird and not ATT, but there must be Thunderbird users that have ATT and have made a seccussful connection. There are a few ATT help pages that outline how to do this, but each time I look at my ATT profile I can not find where to enter the Secure Mail Key. Is there anyone that can help me with this? THanks Mike

Hi!

I can't get messages from my Thunderbird account. When I click "Get messages" nothing happens and it usually says "Done" on the bottom left corner. I have to use my domain's webmail account to get my e-mail and it only allows me to read it and delete junk.

I really would love to have my Thunderbird account working again as soon as possible.

Thanks so much, Nancy Pedersen

After downloading and running installer (Thunderbird setup 148.0) from Thunderbird website, Thunderbird opened as usual, showing my three email accounts. The 2 accounts I use for almost everything are both Yahoo accounts (yahoo.co.uk and rocketmail.com). But.. neither of these accounts will work without a yahoo sign-in pop which is pre-filled with an account name (example graphic attachment : thunderbird01red.jpg). 1 example shown but the same thing happens for both yahoo accounts.

The 'Next' button, which I assume will ask for password, does nothing.

I have attempted login via webmail. I enter account name, am asked for password and Yahoo insists on sending me a verification code - to the other yahoo account (the yahoo.co.uk account), which I cannot access! I then attempt to login to the other account to access my pass code and the same thing happens in reverse, telling me that a verification code will be sent to the first account.

Via Thunderbird, which has for years done all this automatically behind the scenes, I can get absolutely nowhere. Via webmail, I am in an 'impossibility loop'. I have cleared cache for each account.

Why won't Thunderbird allow automatic account login, as has been the case since the year dot. These are the 2 accounts around which my entire life is ordered - can somebody please help.

I received this message: Unable to connect

The connection was refused when attempting to contact localhost.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.

I am not receiving new email. What do I need to do to get it working again?

So here is the issue, I understand the security has been changed to OAuth2, and both the inbound and outbound settings are such. But Thunderbird wants me to log in, OKAY, it will send me the screen with my email account, but will not change after clicking "Next" to allow me to enter the password, regardless of how long I wait. If I click a second time I get the message " Edge: Too many requests"

What needs to be done?
