I received your email & file OK but I'm getting an unavailable mailbox error when I try to send back (I've disguised the actual email address in the message I get back below):

"A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

outlook_"alpha numeric string"@outlook.com: SMTP error from remote server for RCPT TO command, host: outlook-com.olc.protection.outlook.com (104.47.40.33) reason: 550 5.5.0 Requested action not taken: mailbox unavailable. [CO1NAM03FT011. eop-NAM03.prod.protection.outlook.com]"

I suggest you try sending again by a different method/alternative address.
