I have Microsoft Exchange 2016 and I would like to create notifications for users, when they get new message on account user1@example.com, they will automatically receive notification (NOT FORWARDED MESSAGE!) on the mailbox user1@yyy.com
yyy.com is completly diffrent mailbox and mail server.
I tried to do it through mailflow on exchange administration center: TUTORIAL but in new rule I can only send notification to user, whose account is on example.com exchange server.
