How to enable reception of only mails from one user in outlook?
I am planning to enable reception of mails only from one user and block all the mails from all other email IDs. Is it possible to allow one and block all. I am aware of the fact that I can block the contacts individually, but problem is if I don’t know the email ID itself, how could I ever block the mail IDs. My requirement is to allow only person’s mail to be received by the system. All other spams, unwanted mails shouldn’t even get into inbox. Please help.
