You might notice that certain email address is not receiving task notification emails (upon task completion or failure).
Most likely email address is suppressed and not receiving the notifications. Make sure that you tested with other work or personal email addresses and ensured that these notification emails are delivered fine to other mailboxes.
Open a service request where you mention that the task notifications are not delivered to the specific email address.
Support will investigate and unsuppress the email address if it has been confirmed to be the root cause of the issue.
