Keep working on the files your colleague worked on yesterday
Have you discovered the Office 365 home page? Your personal home page with links to files that are of interest to you. It could be the agreements the colleague worked on yesterday or the presentation someone else started and that you are going to finish.
You can find the home page by clicking on the link “Office 365" in the upper right corner of the App window (“Waffle”)
Recommended
Below your apps, you'll see “Documents” with the “Recommended” and “Recent” subheadings. This section is dynamic and the content changes depending on which files are used by you and within the organization.
The Recommended header displays files that you and your colleagues have worked on, viewed recently, or use frequently — with preview so you can quickly determine which file to work on.
How does Office 365 determine which files to recommend?
Office Graph is a service that is in the background in Office 365. Using machine learning, Office Graph continuously collects data about which documents are opened and used, which people communicate a lot, use the same files or receive the same files in mail, and so on and so on. A large number of parameters that are used, among other things, to determine which files are of interest to each individual user. Therefore, you're more likely to be recommended files from someone you know worked with than from someone you've never collaborated with before.
The same data is also used to determine which files appear in Activity in SharePoint and in Microsoft Delve.
Latest
The “Recent” tab displays various Office 365 documents you recently opened and helps you find back to that Word document you worked on most recently. Although the file structure is clear and simple, it may happen that you have to browse through folders and test open files to find the right one.
You can also pin (pin) documents you work with frequently (via the Recent tab in e.g. Word or Excel) for quick and easy access.
Recent, Pin and Shared are also “app-specific” in Word, for example, and then only contain Word files - so you can easily pick up where you, or your colleague if you shared a document, left off.
The “Interesting” tab contains documents your colleagues have worked on or commented on, making it easy to collaborate on documents — you don't need to know exactly what the colleague named the file or whether it was a Word document or a OneNote note to find the right one.
