I have the entire system running and I now I am just running through tests. I have left my old MX records in place and put exchange online one in highest priority.
the current MX record I am meant to be using is according to the DNS?
MX 0 @ domain-vic-edu-au.mail.protection.outlook.com 1 Hour
When I run the Mail Flow configuration I get the following error.
The Microsoft Connectivity Analyzer failed to verify the proper configuration for the MX record or the outbound connector associated with domain 'domain.vic.edu.au'.
Am I do something wrong or is my MX record incorrect.
Goal is to have all inbound and outbound mail flow though exchange online protection
