How to Configure ActiveSync Virtual Directories in coexistence between exchange 2007 and 2013, when you have different external and internal namespaces




In coexistence environment (exchange 2007-2013), we could set Exchange 2013 ActiveSync External URL to mail.yourexternaldomain.com and set Internal URL to mail.yourinternaldomain.com. And set Exchange 2007 Internal URL to mail.yourinternaldomain.com and set External URL to Null. 

We could run the following commands.

Set-ActiveSyncVirtualDirectory -Identity "<CAS2013>\Microsoft-Server-ActiveSync (Default Web Site)" -ExternalUrl "https:// mail.yourexternaldomain.com /Microsoft-Server-ActiveSync"  –InternalURL “https:// mail.yourinternaldomain.com /Microsoft-Server ActiveSync”

Set-ActiveSyncVirtualDirectory -Identity "<CAS2007>\Microsoft-Server-ActiveSync (Default Web Site)" -ExternalUrl $Null  –InternalURL “https://mail.yourinternaldomain.com /Microsoft-Server-ActiveSync”
