I have an a record (*) which points all traffic for *.sub.domain.com (i.e. test.sub.domain.com) to a public IP Visiting test.sub.domain.com correctly directs me to my IP. Woot.
I then added the following records:
cname: autodiscover.test-> autodiscover.outlook.com mx: test-> test-sub-domain-com.mail.protection.outlook.com txt: test -> v=spf1 include:spf.protection.outlook.com -all
After I update the DNS visiting rest.sub.domain.com no longer works
I know cname records can conflict with A records etc - so I was surprised! Suggestions?
