Can not add the user because a user with that name already exists …

This issue occurs when:

You created a user account in the Active Directory. You added the user to your site. Then you deleted the user account from Active Directory and created a new user account with the same logon name as the user account that is deleted. Now you try to add the new user account to your site that you created in Active Directory.

Here is the solution:

Go to the following url:

http://ServerName/_layouts/1033/Siteusrs.aspx

OR

 
Here you can reach through Site Settings -> Go to Site Administration -> View site collection user information. Remove the user that you are trying to add.

Now go back to Site Settings –> Manage Users and add the user as you do it normally. It should work!

 Hope this helps–

    Thank You, I was so confused as to why this error was occuring….turns out that the System Admin had changed the name of one of the security groups and this caused a few issues with Sharepoint.

    Great Solution Thanks Again
