Preparing the computer that hosts
BEMS
 for use with
Skype for Business

If you plan to install
BlackBerry Enterprise Mobility Server
 (
BEMS
) 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 on supported OS versions, see the BEMS Compatibility Matrix.
To prepare the computer for
BEMS
 installation, perform the following actions in order 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

     and run the following script:
    Set-ExecutionPolicy -Scope CurrentUser RemoteSigned

    Microsoft .NET Framework
     4.6 or later is installed and enabled. For more information, see .NET Framework system requirements.
