Currently, we do not support the file being uploaded if the Word or Excel document has macro enabled in them.
According to the conversation with Vinaya, she stated there are no particular justifications for why we are refusing to support such documents and suggested in raising an S4.
I don't have any sample documents right now, but we can test the scenario with any file that has macro enabled file.
Expectation: The user should be able to successfully import a file that has macro support.
