The main difference between Forward Address and Forward SMTP Address management actions is that the first one is used for internal forwarding while the second one is used to forward SMTP address to external users.

Forward Address: specify to which internal user you want to forward the mailbox. Checking the box to “Save Local Copy” will deliver mail to the original mailbox and forward to the new destination. This action will produce an error if you try to use it to forward to an external email address: "Couldn't find object []. Please make sure that it was spelled correctly or specify a different object."

Forward SMTP Address: specify to which external forwarding email address you want to forward the mailbox. You can also choose to save an original copy of each email in the user’s mailbox or only retain emails in the forwarding mailbox. This action will also allow you to forward to an internal user mailbox without producing an error.

The results of these actions are visible in different columns under the 'Users with forwarding' report on our portal. 

  • The result of the Forward Address action is available under Forwarding Address SMTP column in the report and Has external forwarding is marked FALSE.
  • The result of the Forward SMTP address action is available under the Forwarding To column and Has external forwarding will be marked TRUE or FALSE based on the domain name of the forwarding address.

Here is some additional information about columns available in the the 'Users with forwarding' report:

  • Forwarding Address: This is the internal user identity in Exchange of the user receiving the forwarded mail. This is not an email address.
  • ForwardingTo: This is the ForwardingSmtpAddress retrieved from Exchange.
  • ForwardingToRules: These are all InBox rules found. This field will display the email addresses that are receiving the forwarded mail.
