Migration to Exchange Online
Moving an on-premise Exchange environment to Exchange Online, with SPF, DKIM and DMARC fully configured.
- SPF
- DKIM
- DMARC
Starting point
The existing Exchange installation ran on local servers. The goal was to move to Exchange Online without interrupting email traffic during the switch.
My role
Planning and executing the migration, configuring DNS records and securing outbound mail.
Solution
Migration plan with a zero-downtime strategy so that email kept flowing throughout the switch.
Moving the mailboxes to Exchange Online and connecting the clients to the new environment.
SPF, DKIM and DMARC fully configured so that outgoing email is properly authenticated.
Outcome
Email service continued without interruption during the migration.
Outgoing email is authenticated with SPF, DKIM and DMARC.
No on-premise Exchange infrastructure left to maintain.
