Advanced Threat Protection in Office 365 does this as well. It's a security feature that scans all linked files and attachments sent through Outlook.

A while back in my company we were deploying a client management tool (think TeamViewer but with more background management and software deployment capabilities). It needed to be very easy to install, so we just had a link to an EXE file that needed to be opened by our on-site IT departments. No extra steps were required.

Imagine our surprise when we suddenly saw machines popping up that were totally unfamiliar. These were machines connecting from a Microsoft IP, and all had random (but similarly formatted) usernames. They also provided random mouse inputs. We could even take control of these machines (!) but apparently they were short lived VMs that only existed for a few minutes before being recycled.

I contacted Microsoft support because at first we thought this may be a manual process (because of the mouse inputs and the user names), and we didn't want Microsoft employees seeing user data. Afterwards I also commented to the support person that someone may use these temporary machines as an attack vector (to use as an anonymous source, or in a DDoS attack), but the ticket was closed and if I recall correctly this was deemed "working as designed".

Anytime somebody here would like to claim that 'new' Microsoft is so much better and moral than 'old' one, I want to punch them in the face and start rant about Windows 10. Never met a single person, IT or not, who would not complain about it after moving from Windows 7.

Now I don't have to, I can just point to this thread and this comment.

This is pure arrogance - they know they have whole corporate world stuck with Office, even immediate move to Open source would take 20 years due to mostly Excel tight integration/expertise. We would all benefit from a good competition in this area...
