Migrations done right

Everything you need to move mail, calendars, and contacts between platforms — without losing data or interrupting your team.

Zero downtime

Users keep working while mail migrates in the background. Cutover happens on your schedule, not ours.

No size limits

Migrate mailboxes of any size — archives, shared boxes, and public folders included, with no per-GB surprises.

Smart deduplication

Duplicate messages are detected and skipped, so nothing lands twice and folder counts stay clean.

Pre-flight checks

We validate source and destination access, throttling limits, and folder mappings before a single message moves.

Error reporting

Per-mailbox logs flag any skipped or retried items so you know exactly what happened, message by message.

Privacy & compliance

Encrypted in transit, least-privilege access, and audit trails to help meet your compliance obligations.

How it works

Four steps from first connection to final cutover — with a checkpoint before anything moves.

1

Connect your accounts

Securely authorize the source and destination with OAuth or app credentials. We never store your mailbox password.

2

Run a pre-flight check

We verify access, measure mailbox sizes, detect throttling limits, and map folders so there are no surprises mid-run.

3

Migrate in the background

Mail, calendars, and contacts copy across while your team keeps working. Track progress per mailbox in real time.

4

Review and cut over

Check the per-mailbox report, re-run anything that needs it, then switch MX records when you're ready.

Every major platform

Move between any combination of these — in either direction, including hybrid and on-premise setups.

Common questions

Still unsure about something? Get in touch and we'll walk you through it.

How long does a migration take?
It depends on mailbox size and provider throttling. Most single mailboxes finish in a few hours; large multi-mailbox tenants run in parallel over a day or two. Nothing is lost if a run pauses — it resumes where it left off.
Will my users experience downtime?
No. Mail copies in the background while everyone keeps working in the old system. The only switch-over moment is the MX record change, which you schedule.
What happens to folders, labels, and calendars?
Folder structure is preserved and mapped to the destination's equivalent — Gmail labels become Outlook folders, for example. Calendars and contacts migrate alongside mail.
Do you keep copies of our email?
No. Messages stream through in transit and are not retained after a migration completes. We keep only migration metadata such as counts, status, and error logs.
What if a message fails to copy?
Failed items are retried automatically with backoff. Anything still outstanding is listed in a per-mailbox error report so you can see exactly what happened and re-run it.
