I have three groups in a sharepoint site Members- Contribute, Limited Access Owners - Full Control,Limited Access Visitors - Read, Limited Access
why does it say limited access?any suggestions?
Limited Access means a SharePoint user or group has permissions to an item or document or page or library within a Site, but does not have permissions to the entire Site.
This is normally used when you want to share content that resides within a site with users but not allow to browse the site.
See the following Microsoft TechNet article for further help on the subject.
