Netsuite and Microsoft Intune

As a company we are installing Microsoft Intune to help with security. As a result of this we are now unable to open excel exports from Netsuite as these are in the 2003 format .xls which Intune sees as a big no no as this format is now unsupported.

using .csv still works but presents lots of formatting issues which we are keen to avoid.

Any thoughts / solutions
