Teams and MFA - Cannot find an overload for "AcquireTokenAsync" and the argument count: "5".

[NikCharlebois]

There is an issue with Teams and MFA where we are not able to get the MFA prompt to appear when running Export-O365Configuration. It works fine when running it with Test-MSCloudLoginAssistant directly. The popup never appears. It appears that the ADAL object created has an extra property on its AuthContext when executed through the Export-O365Configuration path. The OwnerWindow property isn't on the object when using the direct Test-MSCloudLogin route. We need to determine what the difference is here.
