Here we are the final article for this series dedicated to Exchange installation. The purpose of this one is to configure the internal and external URLs to access the Exchange Services, namely:
-
OWA
-
ActiveSync
-
ECP
-
OAB
-
MAPI over HTTP
-
AutoDiscover
Now in my scenario for this lab I’m using a single-split DNS configuration so I have to create a CNAME record in just one location which will be internal DNS Server for my lab. Of course for production scenarios or when an “external” pointer is needed then the necessary records have to be created in the external DNS servers as well. For my lab I will be using something classic like mail.domainname.com to access services internally and “externally” for my lab. Here we go:
Configure OWA Service
From the Exchange Control Panel page let’s go into Servers > virtual directories and double-click on each one of the components we want to configure starting from OWA service

In my case the URL will look to something like https://mail.domalab.com/owa I will use it for both internal and external URLs

Configure ActiveSync

Configure ECP

Configure OAB

Configure EWS

Configure MAPI over HTTP
We can actually configure this through a single PowerShell command
“Set-MapiVirtualDirectory -Identity “ExchangeServerName\mapi (Default Web Site)” -InternalUrl https://mail.domalab.com/mapi -ExternalUrl https://mail.domalab.com/mapi -IISAuthenticationMethods Negotiate”
To verify the MAPI configuration
“Get-MapiVirtualDirectory -Identity “ExchangeServerName\mapi (Default Web Site)” | select server, internalurl, externalurl”

Configure AutoDiscover
Let’s use PowerShell again!
“Set-ClientAccessService -Identity ExchangeServerName -AutoDiscoverServiceInternalUri https://autodiscover.domalab.com/Autodiscover/Autodiscover.xml”
To verify the configuration
“Get-ClientAccessService | select AutoDiscoverServiceInternalUri”

And we’re done! Now we can use a simpler URL to access the Exchange Services!
