MOSS 2007 allows users to send an e-mail to request additional access to a site. But do you know who this e-mail goes to? Or for that matter do you know where to go to configure this?
This setting is available from the Site Permissions page. To access this go to Site Actions – Site Settings – People and Groups. Now click on the Site Permissions link in the left hand panel. From this page you can select Access Requests from the Settings menu.
If you cannot see this menu item you (or your SharePoint Administrator) should check that the Outgoing Mail Server setting is configured for your environment. This is done through the Operations section of the Central Administration site.
So how does SharePoint determine what e-mail address to use by default? It's simply whoever initially created the sub-site. It can only be set for sites that do not inherit permissions.
So here's a pop quiz for you: Let's assume Bob created a sub-site called Department X along with a child site called Projects. Initially Projects inherits its security settings from Department X. Then Sue comes along and configures the Projects subsite to use unique permissions. Who do you think SharePoint will use for the Access Requests settings?
I'll give you a hint, the answer rhymes with True.
