Unable to cast object of type 'Message' to type 'Attachment'

[dzgreen]

This very helpful module, seems not to be able to perform Get-MsgAttachment when the attachment is also an msg file.

Error:
Get-MsgAttachment: Unable to cast object of type 'Message' to type 'Attachment'.

The same error on Windows Powershell 5.1

Any help would be greatly appreciated.
