Move your active inbox. Keep your history independent.
A provider change should decide where new mail goes, not whether the past remains usable. Preserve supported Gmail or Microsoft 365 history in AtArchive before the old account is closed, downgraded, or forgotten.
AtArchive is not a mailbox-migration service that writes old mail into your new provider. It gives the old history an independent archive so the provider switch and the preservation decision are no longer the same thing.
Why separate history from the migration
The new provider does not need to become the new owner of your past.
Keep the old history searchable on its own
Search preserved records by people, organizations, dates, attachments, phrases, and other available context without relying on the retired provider.
Preserve provider boundaries
An archive can keep source/account identity visible instead of pretending several historical inboxes were always one mailbox.
Make the next switch less consequential
Once history has an independent home, changing the active provider again does not have to restart the preservation problem.
Switch without making history collateral damage
Preserve first, then move forward.
Archive the old provider
Connect the supported Gmail or Microsoft source while the account is still active.
Verify the historical archive
Open old messages and attachments you recognize before treating the source as disposable.
Move new communication separately
Set up forwarding, DNS, migration, or a new mailbox using the provider tools appropriate to your active-mail move.
What AtArchive contributes
AtArchive is optimized for historical preservation and retrieval rather than active mail delivery.
- Supported Gmail/Google Workspace and Microsoft 365/Outlook historic email ingestion.
- Multiple archives can be managed while preserving account boundaries.
- Search and archive views continue to operate on the history AtArchive actually holds.
