The 'Original' Bug

[The team marked this bug as a duplicate of the following bug]

Incomplete error message for invalid email addresses

The error message when adding, editing to an email address that is invalid is incomplete, the error states that:

Emails should be of the format local-part@domain and adhere to the following constraints:
1. The local-part should only contain alphanumeric characters and these special characters, excluding the parentheses, (+_.-). The local-part may not start or end with any special characters.
2. This is followed by a '@' and then a domain name. The domain name is made up of domain labels separated by periods.
The domain name must:
   - end with a domain label at least 2 characters long
   - have each domain label start and end with alphanumeric characters
   - have each domain label consist of alphanumeric characters, separated only by hyphens,if any.

However, it does not pick up the issue on having two consecutive _ in the email local-part, to fix this, we can complete the error message by adding 3. Local-part should not have consecutive special characters or updating the User Guide for the domain constraints.

## :question: Issue type Team chose [`type.DocumentationBug`] Originally [`type.FunctionalityBug`] - [x] I disagree **Reason for disagreement:** I disagree with this as it is a bug related to system testing where it is testing invalid inputs for the email validator. There is inherently nothing wrong with the documentation, but the error stems from somewhere in the code.
