Email & communication

Moving mailboxes

Changing provider without losing mail

What this is about

A change of provider is usually underestimated: folder structures, calendars, contacts and incoming mail all have to move. We mirror everything beforehand, then switch over and reconcile afterwards.

What is included

  • Complete transfer of messages and folders
  • Calendars, contacts and tasks
  • Parallel operation during the changeover
  • Reconfiguration of all devices
  • Follow-up reconciliation for late arrivals

Process

How we go about it.

Survey

Mailboxes, sizes, special cases.

Mirror

Initial transfer in the background.

Switch

Change the DNS records and reconfigure devices.

Catch up

Transfer the remainder and close the old accounts.

Frequent questions

This is what we are often asked.

How long does it take?

The transfer runs in the background, often overnight. The part people notice is reconfiguring the devices, usually half an hour per workstation.

Is mail lost during the changeover?

No, both sides accept mail for the transitional period.

Also away from Microsoft 365?

Yes, in both directions. Calendars and shared access need particular attention.
