We have a current exchange "User A" that wanted a new email address. The email address she wanted was already used in exchange by "User B" that was no longer being used. So we changed "User A's" default SMTP address to use User B's email. When we did this we got the message MailTips not received when sending a new email from "User A". It is not stopping the flow of email for the user, but it is a error we don't want to have visible. Any thoughts?
I have already unchecked all MailTips
