PowerShell mode

You can set up a PowerShell connection to Exchange Server or Exchange Online. The Sophos Mobile EAS proxy connects to the mail server via PowerShell to control mail access for your devices.

PowerShell mode has the following advantages over proxy mode:

  • Devices communicate directly with the Exchange mail server.
  • Because no mail traffic needs to go through the Sophos Mobile EAS proxy, you don’t need to open a port for inbound mail in your firewall.
  • You can block mail access for unmanaged devices.
  • PowerShell mode supports Exchange Online and Exchange Server, whereas proxy mode only supports Exchange Server.
