We’re currently using Microsoft 365 for our domain and have about four active email accounts that we need to migrate to a new SmarterMail instance on the same domain.

We plan to eventually point the domain’s DNS (MX, etc.) to the new SmarterMail setup, but I’m wondering about the best way to transfer the existing accounts and email data from Microsoft 365.

I see there’s a migration tool within SmarterMail that can pull from M365, but here is my question:

– Is it possible to use the migration tool after we’ve already updated our domain’s DNS to point to SmarterMail instead of Microsoft 365?

Appreciate any guidance or real-world experience on this.

Thanks!
