OK, this is a new one on me.
I got an email in one of my Outlook accounts. It said that a request had been made to cancel that particular Outlook account. Supposedly the email was from Outlook, and it had Microsoft logos and everything. It looked pretty legit, although it sounded really strange that someone would be able to request cancellation of my account.
Looking at the headers seemed to indicate that it had come from outlook.com.gr. Why should Microsoft be handling its email accounts out of Greece?
Of course it had a link in the body of the message to cancel the cancellation. That showed, on the face of it, that it was at Outlook. However, the link really went to a specific directory and file at https://ia601508.us.archive.org. Looking (carefully) at the link displayed a graphic that seemed to indicate that my account was being deactivated, although it never actually got to the end of its progress bar. And, of course, there was a big red "Cancel Deactivation" button which, when pressed, asked for my password to verify that it was me. Simple phishing, trying to steal my Outlook account.
