Yesterday, Microsoft announced the Office 365 for Goverment, today in a blog post, the Office 365 team shared a couple of videos providing insight on the basics of permissions.
"When you are first getting started with SharePoint it can often be difficult to understand exactly how permissions work or how you need to go about configuring them to get the specific access you need for your users. The videos have been created specifically to highlight how to work with Office 365 sites, however most of the information presented can also be used for on premise or hosted scenarios," the team posted.
