Friend's email suddenly going to Junk folder
For the last few days, emails from a close friend, whom I regularly exchange emails with, have ended up in the Junk folder. She's using the same address as always, and this address is on her card in Contacts.
Does anyone know what's going on here and I how I can make her emails go to the In Box like they used to?
Thanks in advance,
