A user is created in CCPv2 with a e-mail address which is used as login name. On attempt to create a user with the same e-mail address (login), which already exists on the account, but some of the characters are in uppercase - the user is not created and no errors displayed.
Example: A user with the login
email@example.com exists on the account. On attempt to create another user with the login
User@example.com no errors will be displayed, which is incorrect. At the same time, when trying to create a user with the login
firstname.lastname@example.org, the following error is displayed (which is correct):
The email email@example.com belongs to an existing user. Try a different email address.
Such behaviour is considered a software issue APS-42638 and is planned to be fixed in future product updates.
Please contact your Technical Account Manager in order to clarify current status of the issue.
