Last week I was activating the calendaring option on our new X30, since that moment the O365 account connected for the calendar is marked as High Risk in our O365 portal. I Now want to find out if the related IP addresses are from the Poly Proxy so i can mark them as falls positive. The corresponding IP addresses from the nslookup of otd.plcm.vc are not corresponding with the IP addresses seen by Microsoft. is there any list know where i can crosscheck the IP addresses?

Attached is the list of IP addresses marked by Microsoft
