If you use our domain hosting or nameservers, you don’t need to make any DNS changes as this will be done for you. For third party domain hosting, you will need to make the following changes:
Automatically configuring your mailbox
Automatic configuration through Autodiscover is Microsoft’s primary mechanism for Outlook configuration and is preferred. Autodiscover is also used after the initial configuration of Outlook to periodically poll Exchange for any configuration changes.
Autodiscover attempts a DNS query for “_autodiscover._tcp.[Domain name]” . If your domain name is registered with our nameservers then the Autodiscover record will automatically be configured.
If you use 3rd party nameservers please ensure the following SRV record is created:
Service: _autodiscover
Protocol: _tcp
Server: cluster1.exchange.outitgoes.com.
Port: 443
Priority: 0
Weight: 0
It can take up to 48 hours for some third party hosts to propagate these settings. Once completed, you can set up your email client (such as Outlook) and your smart phone using autodiscover.
