Office 365    
Office 365 is a subscription service from Microsoft and not a version of Office/Excel.

Office 365 is suitable for VT provided your plan includes a license to download desktop Excel (most do except the cheapest).

VT should always be installed (or installed again) after you have installed Excel, and the VT installation program will give a warning message and will not proceed if it cannot find a suitable version of Excel.
