Microsoft contact

[David Bass <davidbass570 () gmail com>]

Hi everyone, hope y’all had a great holidays.

I’m looking for a Microsoft Office 365 contact who can help us…we’re
struggling to get anywhere using the standard methods.

We have a customer whose subnet is blacklisted, and is causing a lot of
heartache.  We’ve proven to a couple of people at this point that Microsoft
is blocking inbound traffic from this subnet, and so they can’t
send/receive emails or access M365.  This is a new eyeball network, so
needless to say that it’s painful.

Appreciate the help!

David
