Your domain can move without dragging your history through every provider change.
When you control the domain, the address may stay the same while the provider underneath it changes. Preserve the old hosted mailbox first so historical access does not depend on keeping the previous tenant alive.
Archive the supported source before changing or cancelling the old hosting relationship. AtArchive preserves history; DNS, mail routing, mailbox creation, and delivery migration remain part of the provider move.
What changes when the domain stays but the provider changes
The address can look stable while the underlying account is completely different.
Old mail may remain tied to the previous tenant
A familiar address does not guarantee that years of messages will follow automatically to the new hosting environment.
Provider search history starts over
Even when mail is migrated, provider-specific indexing and account context can change. An independent archive gives the old record its own retrieval layer.
Business context may outlive the old host
Client, vendor, and project correspondence can remain useful long after the service contract that originally stored it is gone.
Decouple preservation from the provider move
Treat historical mail as its own migration concern.
Archive the old hosted mailbox
Preserve supported mail while the existing provider account still works.
Verify historical records
Check representative people, dates, attachments, and older conversations.
Move the active domain separately
Change DNS, destination mailboxes, forwarding, or migration settings using the new and old providers' active-mail tools.
Custom domain does not automatically mean personal ownership
Business domains may represent company, client, or shared records.
- Preserve only material you or the business are authorized to retain.
- AtArchive does not change DNS or transfer your domain.
- The archive is independent of the new active-mail provider.
