pick the account that says account type pop in Server settings. It is up to you to work out which account you added and which is the pop account you want to remove.

Thanks, Matt I clicked on Server Settings and got the reply "An Account with this name already exists. Please enter a different account name". Every item I clicked on gave me the same message whether I chose my original email address or the repeated email address. I clicked on the email address which was highlighted but nothing happened at all! Back to square one?

You have two accounts with the same name. I suspect one of them is "Local Folders" but you appear, like some other users, to have chosen to rename it.

Go to Tools|Options|Advanced|General→Config Editor

If challenged, tell it you will be careful.

Type mail.accountmanager.localfoldersserver into the search box. (Better than typing: copy and paste it from here.)

It should show you something like server2

Copy that into the search box and add .name, replacing the previous string:

server2.name

Now you will be shown the Local Folders account's name. Double-click it and change its name to Local Folders

Close out, close Thunderbird and re-start.

You should now be able to open Account Settings.

when you get the error message, add a 1 to the account name where the cursor is blinking. Click ok and then go back now you do not have two accounts of the same name.

Hi Zenos I followed your instructions but it did not make the slightest alteration to the fact that Account Settings does not show POP3. I can open Account Setttings fro Tools but am confronted with the situation as per my opening comments.

Hi Matt The cursor does not blink. My email address is shown (second one) which is Highlighted in blue but when I click on it ----Nothing!.
