Mail Routing Overview

When to use Mail Routing

After a cutover mail migration between Microsoft 365 tenants, moving domain names can take up to 48 hours. To avoid non-delivery reports for any emails sent to those domains, Cloudiway’s platform ensures all incoming mail is routed to the intended user regardless of the status of the domain.
