Create DNS records for Office365

To setup Office365 with your domain you need to create below DNS records :

# First you need to validate domain with TXT or MX record :

If you create a TXT record, use these values:

Record Type Alias or Host Name Value TTL
TXT Do one of the following: Type @ or leave the field empty or type your domain name.
**Note:**Different DNS hosts have different requirements for this field. MS=ms XXXXXXXX
Note: This is an example. Use your specific Destination or Points to Address value here, from the table in Office 365.
Set this value to 1 hour or to the equivalent in minutes ( 60 ), seconds ( 3600 ), etc.

 

If you create an MX record, use these values:

Record Type Alias or Host Name Value Priority TTL
MX Type either @ or your domain name. MS=ms XXXXXXXX
**Note:**This is an example. Use your specific Destination or Points to Address value here, from the table in Office 365.
For Priority, to avoid conflicts with the MX record used for mail flow, use a lower priority than the priority for any existing MX records. Set this value to 1 hour or to the equivalent in minutes ( 60 ), seconds ( 3600 ), etc.

 

Once you have validated domain we need to below DNS records :

# Add MX record to route email to Office365
