Exchange 2016 DNS Settings

The following DNS settings are needed for our Exchange 2016 setup.

MX 10 barracuda01.hosting.ca

MX 10 barracuda02.hosting.ca

CNAME webmail.<yourdomain> redirect.canadawidehostingservices.ca

TXT v=spf1 a mx ip4:72.15.149.3/24 ip4:72.15.147.128/27 ip4:208.99.206.181/29 a:spamtitan.hosting.ca a:spamtitan2.hosting.ca include:hosting.ca -all

SRV _autodiscover._tcp SRV 0 0 443 autodiscover.canadawidehostingservices.ca.

In your DNS zone editor add a SRV record with the following information:

  • Service _autodiscover

  • Protocol _tcp

  • Name   Enter one of the following values:

    • Enter @ if your registered domain is your cloud-based domain. For example, if your registered domain is companyABC.com  enter @.

  • Priority 0  (or as per your design)

  • Weight 0  (or as per your design)

  • Port 443

  • Target autodiscover.canadawidehostingservices.ca 

  • TTL   Verify that an appropriate TTL is selected, 1 hour is a common default.  (If you are approaching a migration, this should be decremented to allow for quicker cutover)

Change <yourdomain> to your full domain name. For example if your domain name is companyabc.com. The CNAME would be:

CNAME webmail.companyABC.com redirect.canadawidehostingservices.ca
