If you plan to install

 for use with
Skype for Business
, you must verify that the computer that you install
BEMS
 on meets specific requirements.
All instant messaging server platforms require the
Connect
 service to be installed on a computer that runs a supported version of
Windows Server
. For more information, see the BEMS Compatibility Matrix.
Before you install
BEMS
, you must perform the following actions in the order listed.
Complete these tasks on each computer that hosts the
Connect
 service.
  1. Install and enable a command-line shell and scripting tool. On a computer that is running
    Windows Server

    Windows Server
     2019, or
    Windows Server
     2022,
    Windows PowerShell
     is enabled by default. Open
