[AusNOG] Office365 Exchange Security contact

[Martin - StudioCoast]

Hi all,

Does anyone have a contact on the Office365/Exchange security team?
The issue we are seeing is any emails sent from one of our IPs to any 
Office365 customer ends being hijacked and routed to a completely 
different, unrelated Office365 customer.
Looks like they have a global mail flow rule somehow attached to our IP 
without our permission.

I have tried to go through the standard Office365 support channels, but 
so far the representatives have been unable to grasp the issue.

Any help would be appreciated.

Thanks,

Martin
