A user has left the company and I been finding her many different places from main portal http://portal.inhouse.ca to all the site collections, sub sites and SP groups..
Is there a powershell way to delete her from everywhere? (domain\jsmith)
Please see the script below, it "Remove / Delete users from all sites and site collections within a web application.": http://blog.isaacblum.com/2011/02/24/remove-delete-users-from-all-sites-and-site-collections-within-a-web-application/
To loop through all the sites in a portal use foreach. sample below
Implement above foreach code for below if you need to go through each web in a portal.
