Client has sites in SharePoint 2010
A user has changed her last name, and the changed last name is not being reflected on the site.
As a process i made a not of the groups in which the user was added (Ad group was added and she was within that AD group.)
Things done till now :-
1) Tried to get the name/account by accessing this link "<var class="sbody-var" style="box-sizing:border-box;font-family:'Segoe UI', 'Segoe UI Web', 'Segoe UI Symbol', 'Helvetica Neue', 'BBAlpha Sans', 'S60 Sans', Arial, sans-serif;font-size:15px;line-height:20px;"><Site
URL></var>/_layouts/people.aspx?MembershipGroupId=0" but was unable to
find her with her old and or new name (was trying to delete her and add back ).
2) Checked and confirmed that the name was changed in the active directory.
3) Checked UPA and made sure that the Preferred name/display name is as per the changed active directory. (FYI Site is 2010 but consumes UPA from SharePoint 2013)
4) While adding her account on the site i am able to search with the new changed last name, however when i add her account it changes back to her old last name.
5) i am also able to search her with her previous last name.
Please suggest steps to address and solve this problem
