Calendars and shared working arrangements matter as much as the inbox. We review the source environment and agreed migration scope, test representative calendar items and coordinate room or shared mailbox settings where required.

- Planned cutover communication
The solution, explained
Understand what it can do for you.
Map the mail environment
Inventory mailboxes, domains, aliases and shared resources. Check the source platform and the data types supported by the selected migration method.
Validate before the wider move
Run a pilot with representative users and check mailbox access and mail flow. Communicate the changes users need to make on desktop and mobile devices.
Coordinate cutover and follow-up
Plan DNS changes, final synchronization and post-migration checks in a defined window. Source retention and rollback arrangements are agreed before the transition.
