Exchange 2016 and WAF configuration - KB-000038003 Update

Exchange 2016 behind Sophos UTM SG230. Followed the Exchange 2016 and WAF configuration - KB-000038003 to configure.

Clients had intermittent connectivity issues.

Microsoft Connectivity Analyzer - Outlook Connectivity RPC over HTTP test failed - Could not ping RPC proxy - Error 403

Opened a ticket with Sophos and they determined that this was caused by not having /Rpc/* in the exception list of the Webserver Protection - Firewall Profiles.

Support should be updating the KB
