How do you stop the phone from attempting to logon to a deleted email account?

When I first got my phone Skype video was not available so I opened a Yahoo email account so that I could use them for video calls.  I got frustrated with the phone in that about half of the time that I turned it on it would tell me that it couldn't connect to the Yahoo servers due to an invalid password.  Other times it would connect successfully.

I went to the default email app and found an option to delete the Yahoo account.  I even went to the Yahoo web site and deleted the email account from there. 

I thought that I had successfully deleted the account but now I get a message that the phone can't access the Yahoo servers every time I turn the phone on.  Any ideas on how to stop the phone from attempting to access the Yahoo email servers?

I've checked and the email app doesn't list Yahoo and I can't find any reference to Yahoo in the apps section.

Thanks.

Nevermind, I fixed it (I think).  I went into Settings | Accounts & Sync and found Yahoo at the bottom of the list (alphabetically).  I selected it and it had an optiion to delete the account, which I did.

Excellent! I'm glad you were able to delete the unwanted email from your Thunderbolt!
