I came across the following post by MVP Damian Scoles. He made a script to configure the pagefile of the Exchange Server 2019. Download the Set-PagefileExchange2019.ps1 PowerShell script. Save the script in your c:\scripts\ folder. Run the PowerShell script as administrator. If you like, you can copy the script below and paste it in PowerShell.
