You can change the services according to your requirement. Use the command shown below to enable the services. Type 'Get-ExchangeCertificate' in Exchange Management Shell to see if IIS is enabled. Make sure IIS is enabled and the third party certificate installed. Port: All connections will be over HTTPS. In our case we only have a single SRV record so it does not matter what we enter here. A higher value in weight means it is preferred and more connections are sent to it. Should you have two SRV records with the same priority, then weight is factored in. Weight: Weight is used for load balancing multiple SRV records. But we could just have easily made it 0 or 100. In our case we only have one record, so we just went with 10. If it is unavailable the next lowest number will be used and so on. The lowest priority number will always be used first. Priority: If you only have one autodiscover SRV record then it really doesn’t matter what you enter here. This has to be a name that exists on our SSL certificate. Target: This is where we want our Outlook clients redirected. By design autodiscover requests are performed over TCP connections. Be sure to include a single underscore in front of it. By design this is one of the names the Outlook client looks for.

In our case it will append creating a complete record of _autodiscover._.

This will default the record to the parent domain. Target: Outlook will be redirected to this name. Protocol: _tcp Do not for to add '_' at the beginning. Name: _autodiscover Do not for to add '_' at the beginning. The following command will list your SANs/names in the certificate: Get-ExchangeCertificate | fl Issuer,CertificateDomainsģ.1 If you have multiple domains you have to add below SANs to your SSL Certificate:ģ.2 You can have one common name and one autodiscover name in the certificate and redirect all the common names to and redirect all autodiscover to as below:Ī) (common name1) -> A record points to Exchange server IPī) -> A record points to Exchange server IPĬ) SRV record to redirect to as below The below names should be present for a single domain exchange:

Then make sure you have all the required names added as SANs in your SSL Certificate. Then create the below A records in the newly created zone that point to the exchange CAS/HUB server IP or load balancer IP if you have one (as in the screenshot):ģ. Exchange.online (like mine in the screenshot).Ģ. First make sure you have a Forward lookup zone for your domain in your internal DNS server, e.g. Note: Replace 'exchange.online' with your domain name in all the examples below.ġ. Most administrators don't check the complete URLs that Exchange uses for serving MAPI clients or they miss URLs required to set and add certificate names after installing Exchange Server.
