Please refer to https://technet.microsoft.com/en-us/library/jj591328(v=exchg.141).aspx for information on autodiscover URLs.

you will need https://autodiscover.xyz.com/autodiscover/autodiscover.xml or https://xyz.com/autodiscover/autodiscover.xml.

you will also need to publish the DNS records for this internally and externally.

hope this helps

Greetings,

I am in porcess of migrating my Exchange 2007 to Exchange 2013, Please find below the scenario.

Exchange 2007     Single server solution. Not published externally, only for internal emails only.

CAS URL: mail.abc.com

Have another email system hosted with ISP :     xyz.com

Objective: Migrate from Ex2007 to Ex2013

Want to publish externally xyz.com (not abc.com), will do cutover from ISP hosted to my premises, 

MX records for @xyz.com will be pointed from ISP to on-premises, smtp domain will be @xyz.com

Will be added as accepted domain (abc.com will not be published anywhere, not even the mxrecords for abc.com will be used)

Exchange 2013

Configured 2 Mailbox and 2 CAS Server in Exchange 2013.

COnfigured NLB Unicast for both the CAS Server

DNS: Created one split DNS for xyz.com (as the default domain is abc.com) and then configured A record for mail.xyz.com pinting to CAS NLB Virtual IP.

Virtual Directories Config: I have not done any changes to Ex2007 CAS URLs, as the old namespace is no longer required. And new namespace is configured in Ex2013.

For Ex2007 server have done only change in Autodiscover internal uri to https://mail.xyz.com/autodiscover/autodiscover.xml

Have configured below mentioned URL in Ex 2013.

owa (Internal/External) : https://mail.xyz.com/owa

ecp (Internal/External) : https://mail.xyz.com/ecp

oab (Internal/External) : https://mail.xyz.com/oab

Autodiscover (Internal uri) : https://mail.xyz.com/autodiscover/autodiscover.xml

Webservices (Internal/External) : https://mail.xyz.com/ews/exchange.asmx

ActiveSync (Internal/External): https://mail.xyz.ae/Microsoft-Server-ActiveSync

Test Scenarios:

The Autodiscover resolves if put the url in Expolrer https://mail.xyz.com/autodiscover/autodiscover.xml to the xml page, which i think is fine.

But when i run test-outlookwebservices it gives the error.

[PS] C:\Windows\system32>Get-ClientAccessServer | Test-OutlookWebServices -Identity ex2k7@abc.com -MailboxCredential

Also 2013 Exchange users are not able to see OAB, it is  failing while accessing Address book. Says Outlook is not connected or Offline. 

Certainly i have misconfigured the Virtaul Directoies.

Kindly suggest if the above config is fine or any inputs will be appreaciated.

Thanks in advance.

HI Abhi,

Have renamed the Autodiscover Internal uri on 2013CAS-1, 2013CAS-2 and 2007Server https://autodiscover.xyz.com/autodiscover/autodiscover.xml

MY Default Domain DNS name is abc.com

So i have created a new ZOne xyz.com and created a A record for autodicover.xyz.com pointing to CAS NLB.

Checked in explorer https://autodiscover.xyz.com/autodiscover/autodiscover.xml , it is fine

Even the test-email configuration results are succeeding

But when i try to create the account using auto config it fails.

test-outlookwebservices also failing

It shows mail.abc.com in the service endpoint which 2010, why its still pointing to 2010

Best Regards,

Thanks Everyone for the inputs.

The root cause was that i was using self signed certificate. Have issue third party CA Cert and issue is fixed.

I was aware that Self signed certs are not valid. But i never knew that it could fail the discovery and OAB distribution also.

Thanks ag
