 Function Import-MDSExchOnprem {
    <#
    .SYNOPSIS
    Import the Exchange On-Premises PowerShell cmdlets using a MDSCredential

    .DESCRIPTION
    Import the Exchange On-Premises PowerShell cmdlets using a MDSCredential

    .EXAMPLE
    Import-MDSExchOnprem -MDSCredential MyCred1 -ExchangeServer MyServerName

    Import the Exchange On-Premises cmdlets with the stored 'MyCred1' credentials

    .EXAMPLE
    Import-MDSExchOnprem -MDSCredential MyCred1 -ExchangeServer MyServerName -ViewEntireForest

    Import the Exchange On-Premises cmdlets with the stored 'MyCred1' credentials and set the session's ADServerSettings to allow viewing the entire forest

    .EXAMPLE
    Import-MDSExchOnprem -MDSCredential MyCred1 -ExchangeServer MyServerName -Prefix OnPrem

    Import the EXO cmdlets with the stored 'MyCred1' credentials and prefix the cmdlets. For example Get-Mailbox becomes Get-OnPremMailbox. This allows you to load both the EXO cmdlets and Exchange cmdlets in the same session.
