Exchange 2016: Configure URL for Services

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 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 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 -ExternalUrl -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”

To verify the configuration

“Get-ClientAccessService | select AutoDiscoverServiceInternalUri”


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