Storing your documents online gives you access to them anywhere, on multiple devices. Online documents are also easier to share because you can link to them instead of sending email attachments. As an added bonus, you can read and edit Word, Excel, PowerPoint and OneNote documents in a web browser if they’re stored in an online location like SkyDrive.com.

1. Sign in with your Microsoft account at SkyDrive.com.

2. If you don’t have an account yet, sign up for one (You can use your own email address, or sign up for a new one as part of your new Microsoft account).
On the SkyDrive page, click Upload near the top of the page, and upload your files.

Upload to SkyDrive Pro

If your organization has an Office 365 plan, sign in to Office 365. Or, go to your SharePoint site.

1. Near the top of the page click SkyDrive.

 2. Click New Document > Upload Existing File

 SkyDrive Pro is your personal library, but uploading files to libraries in team sites is another good way to share documents.

Use a SkyDrive folder on your device

If you’ve downloaded the SkyDrive app, you’ll see a folder called SkyDrive on your device. Use that folder like any file storage folder. The documents you store there stay in sync with SkyDrive.com.

If you use Office 365 or SharePoint you might see a SkyDrive Pro folder. The files you store there are synced with your SkyDrive or team site library in Office 365 or SharePoint. For more information, see Sync a library to your computer.

Save directly from Office

If you have a recent version of Office you can save documents directly to online locations from your Office program. That eliminates the extra step of saving on your computer, then uploading.

In the newest version of Office

In Office programs, go to File > Save As > Add a Location, and then pick your team site or SkyDrive location and sign in. Once you’ve picked the location, it’s always listed in the places available to save a document. For details, see Save documents online.

In Office 2010

In Office 2010 (Word, Excel, and PowerPoint), go to File > Save & Send, and then click Save to Web (SkyDrive) or Save to SharePoint, and pick a location.

In OneNote 2010, go to File > Share, and then click Web and sign in to SkyDrive, or click Network and pick a SharePoint location.
