Getting email not my own

Running Mail Droid V2.77. Only account I am pointing to is my Exchange 2010 email account. I am using my webmail dns name for the server. While I get all my own mail, for the past several days, I am periodically getting in batches mail that is in now way intended for me. I am not on the TO or CC list and have no reason to believe I am on the BCC list as the emails are work specific on topics / issues that I am in no way connected with. If I check my email in Webmail, these emails are not present.

This problem only began about 3 days ago; but has persisted since then.
