In PowerPoint 2010 you can upload presentations directly to the cloud using the Save to the Web feature. This will retrieve locations and SkyDrive is one of these possible remote locations where to save files. SkyDrive is a cloud storage solution offered for free from Microsoft and competes directly with Dropbox, Google Drive and Box.net
Once you upload your presentation to SkyDrive, you can access it from the new Metro interface on Outlook.com or from SkyDrive location.
Then you can open your presentations online or share the presentation with your colleagues in the same way you did with other web based solutions like Zoho or Google Docs.
You need to click on File and then Send & Share. Depending on your version and release, this may be changed to something like File -> Share. This File menu replaces the Microsoft Office Backstage button that was available in earlier versions if powerpoint and Office programs.
Then click on Save to Web. and now you will be guided to login to your Skydrive account. You can create a free account on Outlook.com if you don’t have one.
Then, you need to choose the output folder in Skydrive. You can create new folders or use any existing folder. Finally save the changes.
Now you can access SkyDrive and look for the file inside the folder.
Once you open the PPT file in your browser it will be displayed in the online powerpoint Viewer.
Alternatively, if you don’t want to upload your PPT to SkyDrive you can upload to other sharing websites like SlideOnline.com
