Found a user with the same tp_Login but different tp_SystemId

Question

I am facing a problem with a user, which worked fine until it has been deleted from the AD because he quit. After months he came back, I created again the user in the AD, the User-Profile-Sync works fine (no errors), but when he tries to open the SharePoint in Chrome or any other browser it doesn't really work, he gets the error Sorry, something went wrong with File Not Found. and in the UlsViewer I find the statement Found a user with the same tp_Login but different tp_SystemId. Try to delete it..

Actually, when I try to get the current user using CSOM in the browser console, I get null. Notice, if I do it on other users it works, so it isn't a code problem.

I used the SharePointManager too, the page https://myportal/my/personal/theUser is missing. I noticed that there are still personal pages of people who have quit years ago and their users have been deleted from AD, so I have no idea why this user is missing and giving problems.

In the list http://myportal/_catalogs/users/detail.aspx the user is not present.

If in the powershell I do followings I get user cannot be found:

Add-PSSnapin *SharePoint*
$web = get-spweb "http://myportal/"
$web.Users.GetByEmail("usersemail@company.com")

Any ideas?

As mentioned in this article,

Run the below command in SharePoint Management Shell. It will update the tp_SystemID.

stsadm.exe -o migrateuser -oldlogin Domainname\OldUserName -newlogin Domainname\NewUserName ?ignoresidhistory
