Recently I got an issue
in my SharePoint 2013 production environment. One of the user display name not
showing properly. Instead of his name, it is showing one of the employee who
left the organization. By checking the user details in AD we got the details. AD
team updated two emails for one user. One is his own email and other email is
one of the employee who left the company. We tracked the issue and updated the
profile AD and ran User Profile Sync. Everything worked well till now.
But user still having
the issue in one site, his display name not showing correctly. Instead of his
name, it is showing employee who left the organization. We are seeing this
issue only for one site collection. Tried different approaches like deleting
user permissions in the site through UI and using PowerShell commands. Nothing
worked.
After Googling the
issue, we got the resolution. We are seeing that issue due caching in
SharePoint site collection. When I remove and add the data in SharePoint site
group, SharePoint site collection user details from all users located in <Site
URL>/_layouts/people.aspx?MembershipGroupId=0
To fix the issue, we
need to remove the user from all users list and read it to the list. But before
that we need to check all the user permissions in the site (including all the
groups and individual permissions) and need to re add all the places.
Hope this
helps.
