permission levels can be very easy if you use the default
settings, but if you want more control you need to understand
how the permissions work. In the demos below Peter Kalmström,
CEO and Systems Designer of kalmstrom.com Business Solutions,
explains how the SharePoint permissions are built and how
they can be changed.
By default SharePoint users have Edit permission. This is
new from SharePoint 2013 and a rather high permission that
even allows a user to delete whole lists. In the first demo
Peter shows you you can set another permission and also
create your own permission level.
SharePoint sites, lists and so on beneath the site collection
level by default inherits the same permissions as the higher
level. You can change this too and set unique permissions
down to item level. In the first demo Peter also explains
how the inheritance works and how you can break it.
Since these demos were recorded, Microsoft has made some
changes to SharePoint Online, so now it is best to reach
the permissions settings via SHARE >Shared with >ADVANCED,
not via the Site settings as Peter shows in the first demo
The second demo gives a tip for easier permission management:
create groups of people who have the same permission. A
team site by default has three groups: Owners, Members and
Visitors. You can add new users to these groups, but you
can also create your own permission groups.
