Over the last few days this error message is popping up for no apparent reason stopping anybody sending me photo attachments. Even one message in my inbox including a photo attachment which I had been able to look out suddenly changed to this message.
All senders are in my contact list. What have microsoft done!! If I uncheck the relevant box in 'Options'; 'Safety Options'; security I can receive/view them but NOT recommended by Microsoft!!
