Let’s be clear up front: the non-desktop versions of Office are no replacement for the full desktop version. Office 365 Online and the Office 365 Mobile Apps both offer a feature set similar to what you’d find in their
Google Docs counterparts. They’re great if you just need the basic features, or if you occasionally need to view or make minor edits to documents (without the compatibility issues you’d run into using Google Docs,
LibreOffice, or another suite of programs).
For example, some of the major features you’ll find missing in the online and mobile apps include:
- Word: You cannot create captions, citations, bibliographies, tables of content. You cannot create or apply styles. And you won’t have access to some of the more advanced reviewing, proofing, or page layout tools.
- Excel: You cannot create pivot tables, apply conditional formatting, create external data connections or references, or access many of the advanced formulas.
- OneNote: You cannot edit embedded files, use optical character recognition (OCR) to translate handwriting into text, use Outlook task integration, or take advantage of template support.
- PowerPoint: You cannot create custom animations, use headers and footers, or integrate Excel charts. You also cannot take advantage of advanced design or reviewer tools.
And there are a lot more, somewhat minor, features you won’t be able to take advantage of in the online or mobile app versions of Office, as well. For a complete list, check out the
Office Online Service Description on Microsoft TechNet. While that list specifically talks about the Office 365 Online experience, most of the same exclusions apply to the mobile apps, too.
NOTE: Some of these features we mentioned are
viewable in the online and mobile app versions of Office; you just can’t create them there. For example, you cannot create a table of contents form in the online or mobile app versions, but you will be able to view one that was created in the desktop version.
