You can use the Exchange Management Shell to configure a user's ability to access CAS services such as ActiveSync, OWA, POP3, and IMAP4. You can also allow or disallow MAPI connectivity and the ability to connect to Exchange using Outlook Anywhere. In this recipe, you'll learn techniques used to control these settings, whether it is done interactively through the shell or using an automated script.
To control access to CAS services for a mailbox, use the Set-CASMailbox cmdlet. Here's an example of how you might use this cmdlet:
Set-CasMailbox -Identity 'Dave Smith' ` -OWAEnabled $false ` -ActiveSyncEnabled $false ` -PopEnabled $false ` -ImapEnabled $false
This command will disable Outlook Web App (OWA), ActiveSync, POP3, and IMAP4 for the mailbox belonging to Dave Smith.
