On Demand Migration: Domain Rewrite

Share your brand between tenants. Merger and acquisition (M&A) deals often task IT teams with meeting a difficult requirement: Deliver a unified email presence from Day One. On Demand Migration (ODM) Domain Rewrite makes it easy for you to enable users to communicate from a common email domain, delivering a single brand to the world while facilitating internal collaboration. With this powerful SaaS solution, you can:

  • Unify email domains across your tenants.
  • Choose which domains to share.
  • Control which users send and receive mail from common domains.
  • Ensure secure message handling with zero delays in delivery.


Day One efficiency

Easily enable business users in all your Microsoft 365 tenants to use a common email domain for both inbound and outbound mail work. From Day One, present a unified brand to the world while empowering effective internal communication and collaboration.

Secure message handling

Messages are securely routed to and from the ODM Domain Rewrite Service with TLS encryption, using certificates that you control. The project wizard walks you through adding custom DKIM and SPF entries to ensure that your organization’s messages are not flagged as spam or spoofing.

Simple granular control

Eliminate the work of manually loading files to match source and target users; simply use the wizard to define attribute mappings. Choose which domain name (new or old) should be used when sending email; emails sent to either domain will automatically be routed to the user’s active mailbox. You can even control which mailboxes have domain rewrite enabled, and in which directions.

Automated routing configuration

Skip the time-consuming, complex task of configuring mail forwarders and transport rules to process rewritten messages. ODM Domain Rewrite automates the process of routing configuration — and even regularly checks to ensure that the configurations you established are still in place.

Integration with other On Demand products

Easily take advantage of other On Demand Migration tools, such as ODM Directory Sync, ODM Domain Move and ODM for Active Directory. You can use the same project that you configured for ODM Domain Rewrite, including your user mappings, tenant connections and local agents.

Security certifications

Quest On Demand is included in the scope of the Platform Management ISO/IEC 27001, 27017 and 27018 certification. It has also successfully completed Type 2 System and Organizational Controls (SOC) 2 attestation, reinforcing our commitment to customer data security according to the industry’s highest standards.
