This how-to explains email forwarding in Microsoft 365 and how to configure it for a user mailbox using CoreView.
Email forwarding allows you to set up a mailbox so that email messages sent to one user’s mailbox are automatically forwarded to another mailbox, either within or outside your organization. This can be useful for maintaining communication flow during absences, role changes, or shared responsibilities — for example, a sales lead mailbox where messages go to the main sales representative and their backup.
Prerequisites
Before you begin, ensure you have the required permissions. Refer to the article “Recipients permissions in Exchange Server – section 'Recipient provisioning' permissions'” in the Microsoft documentation.
Organization policies or security defaults may restrict the ability to forward email to external addresses. Always confirm your settings, and ask your IT security team if uncertain.
How to set up email forwarding using CoreView
Operators are only able to view and manage mailboxes that are part of their defined V-Tenant scope.
- Type “Forward” in the search bar at the top of the page.
- Two actions will show up:
- Forward Email (Address Book)
- Forward Email (SMTP Address)
In both cases, you will be prompted to specify the recipient who will receive the forwarded email. If you check the “Save local copy” box, new messages will be retained in the original mailbox and also forwarded to the new destination.
Behind the scenes
CoreView uses the same Set-Mailbox PowerShell cmdlet, but provides a more user-friendly experience, with granular scopes enforced by V-Tenant boundaries.
