If you wish to be notified regarding emails that have bounced back, for example, from a marketing campaign, you can achieve this by doing the following:
Go into your staff record in Setup > Staff Record - and add your email address or a shared email folder that you can access.
Select Save - log off and log back on for any staff record amendments.
Any bounce backs will then go to this email address.
If you do not have access to this area of the system, then you will need to liaise with your Line Manager.
