The user may be aware that they have another email and asking them if they have another government email is enough to resolve the issue. In the event that they do not know, redirecting them to their HR department for clarification on their email will help.

I was able to find an account with your name. However, the email associated with it is different from the one you have given us. To ensure this account belongs to you, can you verify if you have any other SBA-issued emails?

If you do not have any other SBA emails, kindly reach out to your HR-department for further assistance, as they may be able to clarify if you have any other emails assigned to you or if any corrections in your TMC account need to be made.
