In the Launchbar, right click the workspace, click Properties, and then click Permissions.
Note: You cannot change the permissions assigned to member roles in 2010 Groove workspaces. Depending on your role, you may be able to change permissions in 2007 (or earlier) Groove workspaces.
Select the role for which you want to view or change permissions.
The selected permissions change to reflect the permissions currently assigned to the selected role.
Check or uncheck the permissions to be assigned to the selected role.
Click Apply (if you want to select another role for updating) or click OK if you are done changing permissions.
