I had the smililar issue and it turned out to be the old version of MSOnline and AzureAD please try use the below make sure to uninstall old AzureAD if you have one installed.

 

AzureAD V2 module: https://www.powershellgallery.com/packages/AzureAD/2.0.0.131

MSOnline module: https://www.powershellgallery.com/packages/MSOnline/1.1.166.0

    Sadly none of these have fixed the problem. I can confirm my scripts work with Visual Studio Code. Guess I have to get used to using this instead. Not a bad thing I suppose.

      I'm using something I found online similar to what VasilMichev  posted earlier. This allows me to establish a MFA enabled EXOPSession from within a script I run via the ISE:

      $CreateEXOPSSession = (Get-ChildItem -Path $env:userprofile -Filter CreateExoPSSession.ps1 -Recurse -ErrorAction SilentlyContinue -Force | Select -Last 1).DirectoryName
. "$CreateEXOPSSession\CreateExoPSSession.ps1"

Connect-EXOPSSession -userprincipalname

       Hope that helps.
