I have an address that I've communicated with for a while now. Recently I'm unable to receive emails from this address to my mobile device. My WLM2012 states that it is an Unknown Sender, even though they are in my contacts, in my safe senders list, and the Domain is listed in my safe senders list. Every time I click allow and have the person send me another new email the same thing happens, Unknown sender and not sent to my mobile device, and it asks to me delete and block or allow again.

The only time i'm able to get emails from this person anymore is if they reply directly to an email I've already sent them.

Please help. Frustrated!!!
