Head-To-Head: Microsoft Office 2013 Vs. Office 365

File, Storage Capacities

All of Microsoft's subscription-based Office 365 versions include 25 GB of SkyDrive storage, and all but the $4 and $8 versions can edit files online. People using Office 2013 with a free SkyDrive account get 7-GB storage but must switch to a browser to edit those documents online. For attaching files to email, Office subscribers are capped at 25 MB, the same limit imposed by AOL, Excite, Google, Yahoo and others.
