Hello Joe,

First, either clear out any existing MX records, or give them a priority number higher than 0.

Next, create an MX record for your domain:

Priority: 0

Host Name: @

Points to Address: yourdomain-com.mail.eo.outlook.com

TTL: 1 hour

Also create an SPF (TXT) record:

TXT Name: @

TXT Value: v=spf1 include:outlook.com ~all

TTL: 1 hour

Finally an autodiscover record (CNAME):

Host name: autodiscover

Points to Address: autodiscover.outlook.com

TTL: 1 Hour
