Whazzup with both a POP3 & an IMAP?

Which one to remove & how to do it step by step please

edit: moved thread from Firefox to Thunderbird section.

I recently and reluctantly converted from my Eudora mail client to Thunderbird about two months ago and I keep having this same problem. I am not sure if I have the correct settings activated so hopefully someone may be able to advise. I have Windows 10, laptop Accessing a "********@usa.net" address via "smtp.postoffice.net" "port 587" Problem is that my junk, sent, draft, trash messages re download when I log back in again. My understanding is that Thunderbird only downloads the headers whereas my Eudora downloaded the complete message so is the fact that it is only the headers being downloaded that it then re downloads them when logging back in?? It is so frustrating having to wait for these messages to download AGAIN when I am just trying to check my emails quickly. Can anyone advise what I might be doing wrong or what settings may need tweaking? Thank you

Sending of message failed. Unable to authenticate to Outgoing server (SMTP) smtp.kingharald.co.uk. Please check password and verify the Authentication method in Account settings/Outgoing server (SMTP). Emails work ok for a while, then I get a few days of this error message and then it seems to fix itself. It's not working just now. How do I fix this?

Formerly I could decide the window size for the number of minimum visible received emails in the list down to 3. But for any reason the minimum now is 10. Which does that the space for text content is reduced a lot. How can I get back the former possibility?

Hi. Just upgraded to Thunderbird 115.3.2. Where is the 'Mail Toolbar' of previous versions, which used to contain Get Messages, Write, Tab (plus maybe other options). Thanks. MK

I have two principal address books, collected and personal. I can add new contacts to these address books. Under collected, I have three lists of group contacts. I want to add a contact to a list in the personal address book. Searched under Firefox and lots of suggestions to drag n drop. Ha ha, highlighting the contact, the moment I drag it across the box towards the list of address books, I get the no-entry symbol, circle with a bar through it. Why is this happening please? How can I copy across the address books or lists? Why is drag n drop suggested when it doesn't work? I'm using Win 10 Pro vers 22H2 64 bit on a Dell PC. Firefox 118.0.2 64 bit. Your aid will save my mind !

I'm not sure I'm in the right place but I have a problem opening my Thunderbird email. It keeps telling me that it's open and to close but nothing happens. I can't close it and it's not actually open. I've rebooted my computer but Thunderbird still insists it's open. What can I do? I can't access and folders or emails. Should I uninstall it and reinstall it? Really hope you can help me

I used to have an extension or add-on the allowed me to play my own sounds for an incoming email on Thunderbird. However, that seems to have disappeared and I cannot find an add-on that will allow me to to that. I have many sounds that used to work but whenever you do an update to the browser they don't work.

Is there any add-on that you have that will work with my own alerts on Thunderbird or do I need to find another browser?

Sorry for posting this here but no response in TB forum. After I installed the latest up grade TB 115 I have lost all the old emails in my inbox, sent, and trash as well as the ability to use TB as I can't sign in. I get the following prompt when trying to use my account. "Sending of password for user ****@att.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later", and then a prompt to "Enter your password" which does not work, although the pass word shows up in"passwords". The TB account works fine in the Yahoo web account, but I don't keep anything there on a daily basis. The web TB account lets me send and receive mail normally. I haven't changed my configuration ,password or uninstalled TB. My G mail works normally. My android cell also won't let me sign in and asks for credentials per password which is unrecognized.

I could not find a link for asking a question on Thunderbird. I just updated Thunderbird. And I was looking around and changing a few things to see how they look and I have lost the "buttons" to bring it back to the original set up. I was looking to see if there was some form a reset button that would take me back t just after install. I am really not liking what I have changed and I want to go back. Plus, is there a way to move the location of the garbage can, more like the older versions. The garbage can is my best friend. Thanking you in advance, K
