Thunderbird Support Forum

bold textMy emails will not download. Optimum or Comcast or the Geek Squad will not help with 3rd party users. I dont know how to get them to download. I am using a computer that is stationed in Florida, so it has not been used in 9 months.

cant send or recieve eemails for past week get this message???? This message could not be sent because The connection to outgoing server (SMTP) smtp.gmail.com timed out ... Try again ???

I hae no idea why or what to do now if someone could help me that would be great

Sorry I have no idea what any of what is in the Shared Data means

My emails are threading up, even ones that have nothing to do with each other. I've tried 'collapsing threads' in the 'view' menu, but it doesn't seem to help. With so much threading going on, I can't even find some of the new emails that I am alerted to.

Thunderbird displays messages as a long list. It never did that before an update, and now I can not find out how to turn that nonsense off! I don't want to see every message from some person tabbed across the screen when I search for their name. I want to just pick one message, often a recent message.

How do I search for a message from a random person and only get one message I choose to view?

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 !
