Microsoft 365 is the productivity cloud designed to help each of us achieve what matters, in our work and life, with best-in-class Office apps, intelligent cloud services, and advanced security.

Using the online version of Microsoft Office, you can also collaborate and work on documents at the same time as your colleagues. See Microsoft’s Use Office Online To Work Together in Office 365 documentation for details.

You can edit files within OneDrive for Business using the web app versions of Microsoft Office programs, including Word, Excel, PowerPoint, and OneNote. To open a file within OneDrive for Business, click on the file name and choose “Edit Document” and then “Edit in Web App” from the top menu bar. When you share a document with another user, you can choose whether to give that user editing rights. OneDrive for Business will remember the ten most recent versions of edited documents.

If you use the built-in IM function of OWA, you will only be able to contact users with ITS-provided O365 accounts. If you wish to contact non-USC colleagues or other commercial Skype account holders, you will need to use the Skype for Business (Windows or Mac) client. See the Microsoft webpage below for information on how to do this.
