Turning to the community forums since I'm at my wits end with this situation.
I run a web hosting company, and my IP for some reason is on the Outlook block list, according to the automatic responses. Not on any other block list anywhere else, just Microsoft's internal one.
The message I'm getting is:

Now before anybody comments saying "use this form to request removal and wait", I've submitted multiple requests so far and heard nothing back. I have paying clients who are telling me they're going to cancel if I can't get this sorted out, and all I can do is submit a form to the void and hope for the best?
Surely there's something one of the staff here can do, or guide me in a better direction than "fill out this form, again"
My latest ticket number is ************, can somebody please look into this and tell me why this is happening?
