There are no differences or restrictions to add another account from the same provider in Thunderbird: follow the same steps for each one, making sure you use the appropriate email account and credentials (user, password) for each.

If you tried this and it didn't work, it would help to know if you got an error message and what it was.

Hello Fabian - thank you for such a quick response. I managed to add the Bigpond account to Thunderbird but when trying to access my emails in Thunderbird with the new account I get the following message:

"Sending of password for user ..........@bigpond.com did not succeed. Mail server mail.bigpond.com responded: pop operation is not allowed for this user."

I entered the correct password numerous times but to no avail.

I should be grateful if you can help here as I am completely at a loss!

Thank you.

My guess based on the error message would be that they do not offer POP email and you should have created the new account as IMAP.

When you look at the original, Working account server settings does it say IMAP?

If so delete the new account an recreate it using IMAP instead of POP.

Thank you Fabian - all solved. Much appreciated.
