Manage site permissions
Site permission levels are based on SharePoint permission
groups. Members of a SharePoint permission group can either visit the
site without editing it (Site visitors), edit the site (Site members),
or have full control of the site (Site owners).
Important: To change these settings you must have owner permissions on the SharePoint site.
Go to your SharePoint team site.
In the top right corner, click Settings
.
Click Site permissions.
Invite people to your SharePoint team site
To give people access to your site, you can either add
members to the Office 365 group associated with the site or you can
share the site with others without adding them to an Office 365 group.
For more on site permissions, see Understanding permission levels in SharePoint.
In SharePoint Online, to give people access to your site, click Invite people and choose one of the following:
Add Members to Group to add members to the Office 365 group associated with your site. This is the preferred method. Click Add members, enter a name or email address, and click Save.
Members added to the Office 365 group are added to the SharePoint Site
members permission group by default and can edit the site. They also
have full access to the Office 365 group resources such as group
conversations, calendar, etc.
Share Site Only to share the site
with others without adding them to the Office 365 group associated with
the site. Enter a name or email address, click the down arrow to select
the SharePoint permission level, and then click Add.
Sharing the site gives users access to the site, but they won't have
access to the Office 365 group resources such as group conversations,
calendar, etc.
Change site permissions
To change the permission level for an individual or
group, click the down arrow next to the SharePoint permission level for
that person or group and select Full Control to add them to the Site owners group, or Read to add them to the Site visitors group.
Note: To view all members of the Office 365 group associated with your site and their SharePoint permission levels, click members at the top right corner of your site.
Remove site permissions
In SharePoint Online, to remove someone who isn't a
member of the Office 365 group associated with your site, click the down
arrow next to the SharePoint permission level for that group and select
Remove.
Note: The Remove option is only available for individuals or groups that aren't part of the Office 365 group.
To remove someone from the Office 365 group associated with your site, click members at the top right corner of the site, click the down arrow next to the permission level for that member, and click Remove from group.
Advanced permission settings
If you are a site owner, you will see a link for Advanced permission settings where you can configure additional SharePoint permission settings. For more information, see Understanding permission levels in SharePoint.
