Adding additional email address in profile

Keep getting the error,  the account already exists in this profile and cannot be added again.  However, I have went into the registry and deleted any mention of this account and still get the same error.  We are using Exchange 2010 with Hosting Controller 10.0.  Local PC is using Office 2016 32-bit.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
