Please check the user information list on the site you are trying to add new user. It is highly likely that those 2 users have the same username and the old one (claudia) has been deleted. the new one was create with the same user account. You can delete that entry from the information list but you will loose the history (like when the user edited something) Best practice when using SP with AD is to not delete accounts just disable this way you cannot create 2 accounts with previously used user name. You could correct that situation farm wide by using Move-SPUser cmdlet (where the old account and new one will be the same)

  • problem is when i go to the profiel of claudia in the user information list i get redirected to christopher's profile page.

Have you changed the old user information to the new user before?

I ever met a similar issue because a user's information was changed and the change was not updated to user information list.

You can run the timer job “User Profile Service Application - User Profile to SharePoint Full Synchronization” in CA > Monitoring > Review job definitions. enter image description here

  • Unfortunately i wasnt the one who did the changes and i am not sure if her AD account was deleted or disabled. ill check this out. Thanks!

  • hi @Kally_MSFT, i ran a full crawl over the weekend but checked now and still the same. i checked the _catalogs/users/simple.aspx and found that when i click on Claudia's profile, the information is on Christopher.
