The biggest change in Office, unveiled Monday in San Francisco, is how and where users will access files, as Microsoft moves to a subscription model that will allow users' files saved to the cloud by default.
Office files are tied to a Microsoft ID. Once users sign up, they can download the various desktop apps to a certain number of devices, and content -- saved to SkyDrive -- is always available across their tablet, PC and phone, Microsoft said in a release Monday.
Documents are also available offline and will sync whenever a user connects.
Office 15 will be available in three versions, the company said -- Office 365 Home Premium, Office 365 Small Business Premium, and Office 365 Pro plus.
No pricing information has been announced.
A preview is available at office.com/preview until the final version goes on sale, Microsoft said.
