Lets say you are hosting many domains in one Exchange Server .
Your Server has a SSL cert .
With these below entries for example .
Mail.Careexchange.in
autodiscover.careexchange.in
—
Now for every domain you host . you cannot keep adding their entries in your SSL . that’s not going to benefit you . the simplest method is using the SRV record method .
like for the every domain you host . you can create a SRV record.
So that you can get the autodiscover settings from your primary domain .
And Outlook 2007 . 2010 , 2013 can understand it . so that your Outlook can be configured automatically .
Lets see how to create a SRV record for example.
Create a SRV Record for Every Tenant to use the Auto discover Service
Choose Name – _autodiscover._tcp
Type – SRV
Priority – 1
Weight – 0
Port – 443
Host offering this service – mail.careexchange.in
(Host offering this service is my Exchange Server)
In a Practical Scenario , Lets see how to do it on a DNS provider interface .
Lets say Testcareexchange.biz is my tenant (1 of my customer)
For users like web catalyst, you can go to Advanced records and add this way . So that SRV record will work
Example
_autodiscover._tcp.testcareexchange.biz. 1800 IN SRV 1 0 443 mail.careexchange.in.

Wait for DNS propagation for 2 to 4 hours .
To Verify the auto discover setting succeeded properly .
You can use Below Microsoft website .
