Managing personal Outlook.com account settings, security, and privacy
I'm getting the same thing, around 20 or more attempts per day from all over the world. This has been going on for around 6 months now. (I have changed my password multiple times and done the double verification) - they've not managed to get in but am wondering whether I should do the alias thing now.
Worryingly, today, without thinking, I made a schoolboy error, I opened an email in my Inbox from 'Marks and Spencer' which obviously was not from them but had crept into my inbox; I was half asleep and had opened it as I had unsubscribed from them and was annoyed they had sent me an email (Duh!?!).
In my defence it should have gone into the junk folder, and am concerned that Microsoft didn't pick it up and it slipped through, now I'm wondering, did they obtain any information and if doing the alias email is enough.
Sigh!!
