SharePoint
groups are defined at a site level. To see who is a member of a
SharePoint group, you need the right permissions on the site itself. If
you have those rights, you can open Site Actions and select Site
Settings (see Figure 1).
Selecting this option opens the settings page for the site (see Figure 2).
Here, click the People and Groups link under the Users and Permissions
header. The page that opens is the one used to manage security on a site
(see Figure 3). The SharePoint groups are listed in the left navigation pane, under the Groups header.
Click the link with the name
of the group for which you want to see the members. Doing so shows a
list of members—either users (such as John Doe) or security groups (such
as Human Resources). Not all users have display names set, so some of
them might not have anything under the Name column.
If you want to see who the user with the missing name is, just click that user’s picture to open the user information page (see Figure 4).
