Microsoft Office Online has several ways to open documents across its different applications and document managers.
The applications covered in this Web page:
Document managers
The document managers the instructions in this section cover are the home document manager, Word Online, Excel Online, and PowerPoint Online. Home, or Office, contains recent documents created by any Microsoft application. It contains Word documents and OneNote notebooks, for example.
For the other three document managers listed in the above paragraph, they only contain documents that their respective Microsoft applications can create and edit. The PowerPoint Online document manager only contains PowerPoint presentations, for example.
The only difference between the Home manager and the document-specific ones is that each of the document ones has a row of thumbnail images for creating new documents.
To open documents in any of the four managers:
- Simply double-click the desired document, and it will open in a new tab.
- The other way is to highlight the desired document. Then click the three dots to the right of the title. In the menu that appears, click Open in Browsers. It will launch the document in a new tab.

The main document manager is where a user can access all of her documents and folders where documents are stored. Users can sync these folders and documents with their Windows and Mac desktops with the OneDrive app. Linux users can use Insync to accomplish the same thing.
