Under Connectivity, TCP connection test the results are showing "Unblock DNS for URL: *.protection.office.com Test FQDN(s) used were: inst5.protection.office.com
I believe this needs to be updated on the test as I did both an internal and external nslookup and no IP is given.
[Internal]
C:\Users\dfeifer>nslookup inst5.protection.office.com
Server: mdstvdc04.neptune.local
Address: 192.168.10.17
Non-authoritative answer:
Name: protectioncenterprodprvinst5.cloudapp.net
Address: 0.0.0.0
