[Summary] 
Admins may need to perform these actions if a new cloud tenant is created for testing or other purposes. When attempting to add or create a login suffix for a cloud tenant, the following error may be displayed if the suffix is already in use by another tenant:
Error: A login suffix with the name Samsung.com already exists. Please enter a new name and try again. 

There are two different methods to manage the login suffix entries:

• Delete the login suffix
• Rename the login suffix

In order to perform the following actions, Admins will need the ability to log in to each tenant’s Cloud Manager to be updated and be a member of the System Administrator (sysadmin) role.

NOTE — If you are unable to login or recover the default cloud admin account provided during tenant registration or if you don't have a cloud connector to process Active Directory logins for alternate administrators, please contact support for assistance.

Delete Login Suffix — Admins may choose to delete a login suffix from a cloud tenant via the Cloud Manager settings menu if no user accounts are configured to use the suffix. Cloud Manager displays an error message if you try to delete a login suffix that still has user accounts.
To delete a login suffix, remove all of its user accounts or modify the accounts to use a different suffix.

1. Go to Users  > Select User
2. From the dropdown, select a new suffix.

Rename Login Suffix — This option provides the easiest method to allow the login suffix to be used by another cloud tenant. Rename the login suffix to something like “MySuffix-old”. Suffix names must be unique. As example, changing a login suffix named “samsung.com” to “samsung.com-old” allows a different tenant to use “samsung.com”.
