In the world of basic authentication, I used to connect to MSOL, Compliance and Exchange in a series that went like this:

        function ConnectToCloud()
        {
            $CloudCredentials = import-clixml C:\tools\CloudCreds.xml
            Write-Host "Connecting To Compliance Online..." -foregroundcolor white -BackgroundColor Green
            $Session1 = New-PSSession -Name "Session1" -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.compliance.protection.outlook.com/powershell-liveid `
                            -Credential $CloudCredentials -Authentication Basic -AllowRedirection -WarningAction SilentlyContinue
            Import-PSSession $Session1 -Prefix CP -DisableNameChecking -AllowClobber | Out-Null
            Write-Host "Connecting To Exchange Online..." -foregroundcolor white -BackgroundColor Green
            $Session2 = New-PSSession -Name "Session2" -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell `
                            -Credential $CloudCredentials -AllowRedirection -WarningAction SilentlyContinue
            #Import-PSSession $Session2 -Prefix Cloud -DisableNameChecking -AllowClobber | Out-Null
            Connect-MsolService -Credential $CloudCredentials
            Write-Host "Starting the Checks..." -foregroundcolor white -BackgroundColor Green
        }

In the world of Modern Auth, we're supposed to connect to Compliance with: 

    Connect-IPPSSession -Credential $CloudCredentials

and connect to Exchange with:

    Connect-ExchangeOnline -Credential $CloudCredentials

the connect to MSOL hasn't changed.

The problem is that when I run Connect-ExchangeOnline, it DISCONNECTS me from Compliance and vice-versa How can I, in a script connect to all THREE services simultaneously, using modern auth?

Thanks!

    Microsoft documentation https://docs.microsoft.com/en-US/powershell/exchange/office-365-scc/connect-to-scc-powershell/mfa-connect-to-scc-powershell?view=exchange-ps is stating (Optional): If you want to connect to an Exchange Online PowerShell module session in the same window, you need to run $EXOSession=New-ExoPSSession -UserPrincipalName [-ConnectionUri -AzureADAuthorizationEndPointUri ] and then import the Exchange Online session into the current one using an specific prefix Import-PSSession $EXOSession -Prefix EXO – Brice May 02 '20 at 14:30

It seems I was using the "preview" module of the Online connection.

If I use the one that you get via the Exchange Online reference, then the following commands work to connect to BOTH compliance and Exchange Online

        $MFAExchangeModule = ((Get-ChildItem -Path $($env:LOCALAPPDATA+"\Apps\2.0\") -Filter CreateExoPSSession.ps1 -Recurse ).FullName | Select-Object -Last 1)
        Import-Module "$MFAExchangeModule"
        $CloudCredentials = import-clixml C:\tools\CloudCreds.xml
        Write-Host "Connecting To Compliance Online..." -foregroundcolor white -BackgroundColor Green
        Connect-IPPSSession -Credential $CloudCredentials -WarningAction SilentlyContinue
        Write-Host "Connecting To Exchange Online..." -foregroundcolor white -BackgroundColor Green
        Connect-ExchangeOnline -Credential $CloudCredentials -ShowBanner:$false
        Connect-MsolService -Credential $CloudCredentials
        Write-Host "Starting the Checks..." -foregroundcolor white -BackgroundColor Green

Note - I can't use New-EXOPSSession because it won't let me give it a Credential parameter... Interactive logins don't work so well in a script :(
