identical account already exists

I recently deleted my Microsoft Exchange account from my iPad with the intentions of setting it back up. I deleted the account because my mail was no longer coming through after I set up a new iCloud account. I go to settings, mail calendars, and choose to set up a new exchange account. After I finish entering the email, password, username, server info, etc, a message pops up saying that this account already exists even though I deleted it from my iPad. HELP. I need to be able to access my emails ASAP. I already tried to reset the settings. not my whole iPad- just the settings. I'd like to avoid resetting my whole iPad....
