Somewhat related, I ran (and am still running) into a very uncanny issue related to another product of Microsoft: Live / Outlook.

When Live and Outlook got merged (IIRC a couple of years ago), my @msn.com address got an @outlook.com alias.

Unfortunately, this "alias" shouldn't have been one and the email was actually owned by someone else.

By some sort of failed merging, I hence ended up getting access to someone else' emails: PayPal related emails, Dropbox access connected to this email account, private email exchanges, etc...

I tried to reach out to Microsoft but hit (expectedly) a wall.
