Mail migration without the week of chaos afterwards
Mailbox, calendar and archive migration between platforms with minimal user disruption.
The problem
Email migration goes wrong in predictable ways: shared mailboxes and delegate permissions that do not survive the move, calendar meetings that lose their organiser, archives that were never in scope but turn out to be business-critical, and a support queue that spikes for a fortnight because nobody told users what would change.
How we approach it
We inventory everything that touches mail before moving any of it — shared mailboxes, delegates, distribution lists, forwarding rules, connected applications and archives — because those are what break, not the mailboxes themselves.
Migration runs in waves with mail flowing correctly throughout, and users get specific instructions for their situation rather than a generic notice.
What you get
- Full inventory of mailboxes, delegates, shared mailboxes and connected systems
- Wave-based migration with mail flowing throughout
- Calendar and delegate permissions preserved
- Archive and retention requirements addressed explicitly
- User communication targeted to what each group needs to do
- Post-migration support during the period problems actually appear
How the engagement runs
The sequence, and why each stage comes where it does.
Inventory
Every mailbox, shared mailbox, delegate relationship, distribution list, rule and connected application is catalogued.
Domain and routing plan
DNS, mail routing and coexistence are designed so mail flows correctly at every point of the migration.
Pilot wave
A small representative group migrates first, including at least one complex delegate arrangement.
Production waves
Users migrate in agreed groups with confirmation checks after each.
Cutover and cleanup
Mail routing switches fully, the source platform is decommissioned on an agreed date, and archives are verified.
