Using older versions of Outlook for Mac in business environments
I called Microsoft for help and they put me onto a chat with someone who said it was a phishing email and I had to change my log in details and create an alias name as a primary email. I was told not to respond to this email, which now I find out is genuine. I was on the phone for 45min all to no avail at the end. I am just hoping after the 16th I can still receive emails. By the way I am 73 and have children who are of no help to me at all in this matter. I even asked a computer geek to help and he didn't know what to do either!
