Hello,
If a user in a claims authenticated sharpoint 2010 environment gets married, and her email changes from lara.croft@ms.com to something like lara.stark@ms.com, how can I change the username in sharepoint from "i:0#.f|providername|lara.croft@ms.com" to "i:0#.f|providername|lara.stark@ms.com" so that she would be able to log in with the new email as her username using powershell?
