Virtual Directories
Many of the client protocols used with Exchange Server 2013 are accessed through virtual directories.
A virtual directory is used by Internet Information Services (IIS) to allow access to a web application such as Exchange ActiveSync, Outlook Web App, or the Autodiscover service. You can manage a variety of virtual directory settings on Exchange 2013 including authentication, security, and reporting settings.
Set-OWAVirtualDirectory
Use the Set-OwaVirtualDirectory cmdlet to modify the properties of Microsoft Office Outlook Web App virtual directories on a server running Microsoft Exchange Server 2013 that has the Client Access server role installed.

Parameter of Set-OWAVirtualDirectory
The LogonPagePublicPrivateSelectionEnabled parameter specifies whether the Outlook Web App sign-in page includes the private computer or public computer sign-in option.
-AllowOfflineOn
Parameter of Set-OWAVirtualDirectory
The AllowOfflineOn parameter specifies which computers can use Outlook Web App in offline mode. The possible values are PrivateComputersOnly, NoComputers, or AllComputers. The value is set to AllComputers by default. If you set the value to PrivateComputersOnly, only users who log onto Outlook Web App using the Private option are able to use Outlook Web App in offline mode.

Users can turn the feature on or off in Outlook Web App. To turn the feature on, users click the gear icon, and then select Stop using offline. To turn the feature off, users click the gear icon, and then select Use mail offline.
