Thunderbird Community Forum

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.

Hello everyone. Thanks for all your support.

A few weeks ago I started noticing a pop up window was occurring every (approx) 5 minutes in Thunderbird suggesting that I run a compact to save 992MB. I assumed this would stop happening after a few weeks and a few updates from Mozilla, but the problem has remained, so I'm coming here to ask about it.

Context: I'm on Windows 11. I have multiple email accounts that my Thunderbird reaches out to. At least one of the accounts is retired so reaching out to its historical server fails.

Reproducing: For me to reproduce it, I run the compact. Quit Thunderbird. Start Thunderbird. It reports 992MB can be freed. I let it compact. The main inbox disappears and reappears. I wait a few seconds and restart Thunderbird. It again tells me that it can save 992MB by running a compact.

What I've tried: I've tried repair on the inbox folder of the account I'm typically in. That didn't help. I have many other folders across many accounts and not tried to repair any other folders. I've searched the Mozilla help system.

Logs: It seems to me that a compact is probably failing but I don't know where to look for evidence of the failure.

Help. Help. I have been a very happy Thunderbird user for many years. I have linked my microsoft exchange calendar to thunderbird with the TBSync and Provider for Exchange ActiveSync.

With the upgrade to version 148, those add-ons no longer work.

So I downgraded to 140 ESR and those two add-ons were ok.

But when I tried to link them to my calendar, they would not sync. I received 401 and 403 errors from the automated setups. And the manual setup, asked for my password over and over again. They all worked beautifully before.

Please how can I get them to work again. I do not want to have to shift to outlook.

thank-you

I have several emails (personal and business) that I use and have them grouped in Unified inbox. Recently one of those emails showed up as a new folder (just under Trash folder) in bold type. It has with a varying number of emails in it, now 18. When I click on the 'open folder arrow', a subfolder 'Archives' with nothing in it shows up. When I open the email folder a new page appears with the email as a header and underneath 'set up another account', 'import from another program', 'about mozilla thunderbird', and 'resources'. What is happening? How can I get rid of this folder since I can't read any of the emails in it and it is just a duplicate of the folder that already is working find in the inbox? TIA

I had about 7 accounts in ThunderBird already setup and working. Now when I try to setup another account, it goes through until the screen that wants me to click to Allow ThuderBird to get information from Google. This screen comes as fullscreen with no scrolling bars. And there is no icon that I can click on the screen to Allow information sharing. I am stuck here and cannot add any more accounts to Thunderbird.

First - sorry if the post is messy, but I don't see a Preview option today

PRELUDE: When I create a email to send to Joe@hotmail.com, on clicking SEND, a popup wants a password for a different account:

EXAMPLE: (emails are faked here for privacy)

Assume I have the following email accounts:

1. john@fakes.xy
2. jane@morefakes.vc
3. fred@deftly.xc

I compose a email to john@fakes.xy. I click SEND, and there is a popup stating:

Status: Sending message... Progress {progress bar}

and second popup with :

Enter your password for jane@morefakes.vc on mail.{IP name}.com

and a third popup with:

Login to server mail.{ip-name} with username jane@morefakes.vc failed

I have attached a screen cap (redacted) as seen in actual.

SUMMARY:

• When addressing email to Joe, upon SEND, the errors show password to use is listing a different account.

I ran Troubleshooting Mode with no errors, except, same thing. Wants password from a different email account.

Thanks for reading this, ~r

Hello-

   Just today I received this error code when trying to sync with my Outlook account in TB. It tells me that anything under v.16.1 will not work. In the account settings it only allows me to choose from v.2.5 & 14, no 16. How do I update to ver.16?

Thanks, Bob

All my saved mails in my local archives dissappeared about one week ago, probably in connection with a system update of my Thunderbird mail box. These mails are important for me. How do I do to get them back? Best regards, Monica Biander

A few days ago I started getting a failed sign in for one of my emails. The solution seems to be that my authentication method in ≡ > Account Settings > Server Settings does not give OAuth2 as a choice. Screenshot shows what is available. All other email authentication methods have that as a choice. Is this a problem with the email program or T'bird? T'bird is 140.8.1esr (64-bit) O/S is Win11 Thanks for your help

I can't login to my Mozilla email account this morning. My service provider is working fine and I can send and receive emails through them but not through Mozilla. Please advise. Thank you. Tim Cimperman cody46@zoominternet.net

I have been using Thunderbird with two POP3 Hotmail accounts for some time and I am trying to set up a third account with exactly the same configuration. However, both the automatic and the manual configurations failed. The new account receives mail, but the outgoing smtp server config seems to have a problem. Sending messages times out or keeps prompting for a new password.

The Hotmail account has POP3 and IMAP enabled. Thunderbird is set to receive all cookies. I cleared history and cache after every attempt and also temporarily disabled the firewall.

Any suggestions about what the problem could be?
