Maybe Office 365 does not have OLE automation anymore - this seems plausible if Office 365 only runs within the browser, for example.

Maybe look on your PC whether the type library file is findable and give that to Win32::OLE::Const explicitly.

The alternative approach if all this fails is to replace all the named constants with their values, which you can acquire from Googling them.
