When you remove users’ or resources’ GroupWise accounts or delete groups, they are automatically removed from any groups in which they have membership.
NOTE:If the group is being synchronized from an LDAP group, you cannot modify group membership in the GroupWise Admin console. Instead, you must use the same LDAP directory management tool to modify group membership that you used to create the LDAP group. Changes to membership in the LDAP group automatically synchronize to the GroupWise group.
To manually remove members from a group:
In the GroupWise Admin console, browse to and click the name of a group.
On the Membership tab, select one or more members that you want to remove from the list, then click Delete.
