Using Outlook for iOS in business environments for email and scheduling
I got the same email today. Was a little worried until I saw ‘highly controversial porn sites’ as I know I haven’t been and don’t go to those.
I quickly looked it up and found this thread. One thing I noticed was while they mimic your address so it appears they logged into your account, there was no corresponding email in the sent or deleted folder. I highly doubt if they were trying to convince me they hacked my account they would permanently delete the proof that they are real.
