Many of the new features in Office 2013 are geared toward saving and sharing files online. To use these features, you'll need to get a free Microsoft account (previously called a Windows Live ID) if you don't already have one. You can then log in to your Microsoft account to access your OneDrive, which is an online storage space for your documents and other files.
OneDrive was previously called SkyDrive. There's nothing fundamentally different about the way OneDrive works—it's just a new name for an existing service. Over the next few months, you may still see SkyDrive in some Microsoft products.
Here are a few of the things you'll be able to do with your Microsoft account:
If you don't already have a Microsoft account, you can go to the Creating a Microsoft Account lesson in our Microsoft Account tutorial.
When you use Office for the first time, it will ask you to sign in to your Microsoft account. However, if you don't sign in at that time, you can always sign in later.
If you're using Office at home or at work, it's usually more convenient to stay signed in. However, if you're using a shared computer (for example, at a library or business center), it's important to sign out when you're done. This will prevent other people from accessing your OneDrive files.
If you sign in to Windows 8 with your Microsoft account, you'll automatically be signed in to Office 2013, and it will not let you sign out of Office. Instead, you can sign out of Windows 8 to prevent other people from accessing your files.
Once you've signed in to your Microsoft account, your OneDrive will appear as an option whenever you save or open a file. You still have the option of saving files to your computer. However, saving files to your OneDrive allows you to access them from any other computer, and it also allows you to share files with friends or coworkers.
For example, when you click Save As, you can select either OneDrive or Computer as the save location.
You may already have documents on your computer, for example in your Documents library or on your Desktop. If you decide to upload them to OneDrive, it's important to understand that you're actually uploading a copy of each file. To avoid problems, you should only edit the version that is in your OneDrive. If you still have a copy of the file on your computer (for example, in your Documents library), you can either delete that copy or keep it as a backup.
Another solution is to download the OneDrive Desktop App. The app creates a folder on your computer that stays in sync with your OneDrive. You can then simply move your documents into that folder to upload them to your OneDrive. Since the files will stay in sync, you are free to open them either from the folder, or from your OneDrive.
Office 2013 allows you to share documents, spreadsheets, and presentations. Once you've saved a file to your OneDrive, you can invite people to read or edit it. The people you share with do not need to have Office 2013; they can read or make simple edits with Office Online.
With some projects, you may have several people that need to edit the same document. When you share a document with OneDrive, multiple people can edit it at the same time. This is known as co-authoring. Co-authoring can be used with Word and PowerPoint, but it does not currently work with Excel. Each person will need to use either Office 2013 or Office Online.
If more than one person is editing a document, you'll see an icon at the bottom of the screen that shows how many other people are currently editing it. You can see their names by clicking the icon.
Co-authoring works a little differently in each Office program. For example, in Word 2013, you won't see everyone's changes to the document as they make them. Instead, every time you save the document, it will update to show everyone's changes. Also, co-authoring does not work in Excel 2013, but it does work if everyone is using Excel in Office Online.
