Unable to add users to Sharepoint becuase "user already exists"
When you try to add a user to a Microsoft Office SharePoint
Portal Server 2003 portal site or to a Microsoft Windows SharePoint
Services Web site that is hosted on the portal site, you receive the
following error message:
Can not add the user because a user with that name already exists
This issue may occur if the following conditions are true:
- You create a user account in the Active Directory directory service.
- You add the user to the portal site or to the Windows SharePoint Services Web site.
- You delete the user account from Active Directory. You then
create a new user account that uses the same logon name as the user
account that you deleted.
- You try to add the new user account that you created in Active Directory.
This issue occurs because the security ID (SID) of the existing user account does not match the SID of the new user account.
To resolve this issue, connect to the Manage Site Collection Users
page, and then remove the existing user account. After you do this, add
the new user to the portal site or to the Windows SharePoint Services
To do this, follow these steps:
Taken from Microsoft KB 893696.
- Use on of the following methods to connect to the Manage Site Collection Users page:

site, type the following address in the address bar of your Web browser,
and then press ENTER:

connect to the page.
To connect to the Manage Site Collection Users page of a Windows
SharePoint Services Web site that is hosted on the portal site, type the
following address in the address bar of your Web browser, and then
- Click to select the check box that is next to the name of the
user who you want to remove, and then click Remove Selected Users.
Note If more than 100 users are in the site collection, the user may
not be listed on the current page. To view additional users, scroll to
the bottom of the list of users, and then click Next.
- Click OK when you are prompted to confirm the removal.
