Saving and opening files
You can work with the files you store in OneDrive for Business right from Word, Excel, PowerPoint, and other Office desktop apps. There's no need to go to your Office 365 site in a browser.
Save a file to OneDrive for Business from an Office desktop app
With a document open in an Office desktop app, click File > Save As > OneDrive - YourCompanyName. For example, OneDrive - Contoso.
Browse to the location where you want to save the file, and then click Save.
Open a OneDrive for Business file from an Office desktop app
In an Office desktop app, click File > Open > OneDrive - YourCompanyName. For example, OneDrive - Contoso.
Browse to the file you want to open, and then click Open.
Tips: If you don't see OneDrive - YourCompanyName, click Add a Place > Office 365 SharePoint. Then sign in to Office 365 with your work or school account.
Once you add OneDrive for Business as a place in one Office app, you can save files from all your Office apps.
