Configure S/MIME settings for Outlook Web App

As an organization administrator for both Exchange 2013 and Exchange Online, you can set up Outlook Web App to allow sending and receiving S/MIME-protected messages. Use the SMIMEConfig cmdlet to manage this feature through the Exchange Management Shell interface.

For more information such as a detailed description of parameters and examples for get-SMIMEConfig and set-SMIMEConfig, see the Get-SmimeConfig and Set-SmimeConfig documentation.

You can only use the Shell to perform this procedure. To learn how to open the Exchange Management Shell in your on-premises Exchange organization, see Open the Shell. To learn how to use Windows PowerShell to connect to Exchange Online, see Connect to Exchange Online PowerShell.
