I get the following error whenever I start Thunderbird :-

I can no longer download my email from the server to my Thunderbird email client since I removed the specifics for the server with the password. I need to add it back but I don't know how. Is there a file I can edit?

AI tells me I can't just drag my Gmail.com (IMAP) from local Folders to the internet-connected folders section, which contains my Verizon.com account hosted by AOL. How can move my Gmail (IMAP) account safely?

I wish to add email identity deborahstpeter1@gmail.com to my account keweston82@gmail.com. Deborah is in a nursing home and as Power of Attorney I handle all her financial affairs on line. I had to replace my old computer which included Deborah's email in my Thunderbird email account but I've been unsuccessful getting her added to my new computer. I'm 83 years old and operating my old computer, which is where Mozilla's responses are going, and my new computer from which I'm communicating with Mozilla, plus two different mouses, I'm making a lot of mistakes i.e. click a computer scream with the wrong mouse. I wish to add Deb to my account with as little involvement on my part as possible. You can send a verification code to deborstpeter1@gmail.com and I will be sure to use the correct mouse.

I have TB 145.0 on a Mac.

When my trash gets pretty full, I empty the trash then restart TB just to have a fresh start. Been doing this for years. Well, I did it just now and when TB restarted I got a warning that said Thunderbird is an app I downloaded from the internet, do I trust it? First time that has happened.d I clicked on the button that said to go ahead and open it.

When TB opened, it wasn't aware of any of my email accounts. It's almost like I was opening it for the first time – except for 187 random old emails in an inbox.

Is there a way to recover from this? I had a lot of emails stored in inboxes and outboxes that would be disastrous for me to lose. They aren't there right now.

I am trying to add an Proton mail account to Thunderbird using the Proton Mail Bridge (PMB). In the PMB guide it is recommended to uncheck Account Hub in the Setting>General. The problem is that the Account Hub still pops up when trying to add a new mail account - it simply refuses to go away regardless of several restarts of both the computer and the mail client!

My ISP has made a change for "third-party" accesses to its e-mail (which still works fine on its own website e-mail access page). I need to check my Username, Password, SSL, Protocol, Incoming & Outgoing Server Ports. BUT I don't see on my Thunderbird page where to find these: it's my preferred way to do e-mail! Where are they??

I have a Google Workspace account which has my company name as a suffix, ie. @chase-design.net NOT @gmail. com. When I try to add an account automatically using the company suffix, Thunderbird does not recognize it. Is there a set-up guide that shows me step by step how to manually configure that type of setup?

I added a new mail account and then after a week or so decided to remove it. But after removing it I kept getting a popup nag to enter a password for the removed account.

My old provider has stopped supporting my old email address and I have changed to a gmail address. How do I remove the IMAP and smtp settings etc for my old email address? Also remove all trace of that unwanted old address please?

Thunderbird forces me to use the new amount hub. And I get authentication error when trying to setup outlook.com email

I just download the latest version of Thunderbird, and try to add my pop mail account. But after i enter the info of outgoing server settings, the Continue button is gray and can't be clicked. once I try the test, it says that Thunderbird failed to find the settings for your email account. Can't find a server. Also i find that there is no place enter the password of my mail account.

A page appears when I open Thunderbird asking for permission to allow Mozilla Thunderbird to access my google account. It asks for me to click on "allow" but nothing happens and the page keeps appearing.

I need to save all my emails in outlook on my harddrive so that I can change from Imap to POP. Reason being is that optusmail has taken over some of my folders in Outlook and transferred them into optusmail without my permission. All my existing emails in outlook are now deemed to be part of optusmail, so the mailbox is always nearly full. I need to retain my existing email address. I have been advised to make the Imap/POP changeover to restore my control of my emails in Outlook. Will installing Thunderbird allow me to avoid all these other actions to achieve email control ?
