Office 365 settings to view (edit?) docx/xlsx?

That is a good point -- regardless of which version of Office you're using, you do need to match the bitness (32/64) of UR with the bitness of Office. This applies even for older versions of UR and Office (UR v5 was 32-bit only, so you had to use 32-bit Office).

Regarding the Outlook question, do you have the same bitness of UR and Outlook installed, and which one?
