account count restriction

I just started using eM. I set up two email accounts. A couple days later, I tried to set up a third. Didn’t realize I was only allowed 2. Now, every time I open eM, I get a pop up about “account count restriction”. It was my mistake, but, do I have to deal with this warning forever or is there a way to stop it?

Go to Menu > Tools > Accounts and delete the third account.

Thanks. I was under the impression that the account was never created because of the limit message I got when I first tried to add it.
