I'm using a POP server with Outlook 2013 desktop. I deleted an account on the server and within Outlook but it keeps checking for mail from the deleted account. The strange thing is the account is not listed in the Outlook email account lists (File | Account Settings | Email tab). I've re-added the account to Outlook and the server, sent an email fine and then removed it again from both places yet Outlook keeps checking for it and prompting for credentials. I run ESet as a virus protection which has an Outlook plug in and have tried disabling that to no avail. All apps are up to date. Any help would be appreciated.
