With Office it’s easy to work with others, including people who don't have Microsoft Office, because you can send links to documents instead of sending file attachments, which they can review (and edit, if you let them) in Office Online. That saves on e-mail storage and prevents you from having to reconcile multiple versions of the same document.
To get started, store your document on OneDrive
Note: If you are using Office Online for school or work, here is information specific to team libraries and OneDrive for Business.
To send a link, click Share at the top of the Office program window:
When your friends click the link you send, the document opens in their browser.
To edit, they click the command for editing in the Office Online program.
Work with others in Office
When you are editing a file in Office you might see notification that others are working in the file too. There is no special trick to begin working together on a document. You edit as you normally would, and if others are also editing the document, Office alerts you to their presence, and shows you where in the file they’re working.
People can be working in Office 2010, or Office for Mac 2011, or later.
Because Office automatically saves everyone’s changes, the Undo and Redo commands might not work the way you expect.
In Excel, when one person changes the sort order or filters data, the view changes for everyone who is editing the workbook. So, be mindful of sorting and filtering while others are in the workbook.
Work with others in OneNote
If you make your notebook available for other people to edit, your friends can work on the notebook at the same time as you. This works well for notebooks where you are collecting information from a group of people, such as a brainstorming session or a group project. The notebook functions like a wiki where everyone contributes. You can see who did what, and you can revert a page back to a previous version if necessary.
If you or other people have OneNote 2010 or later, you can work in the OneNote desktop, web, and mobile applications while other people are working on the same notebook. You can share the notebook in OneDrive, just like Excel, Word, and PowerPoint documents, but you can also share the notebook in OneNote 2010 or later.
Click the File tab, and on the Info tab, click Invite people to this notebook, under the name of the notebook.
