First public release.

Exchange Mailbox Migration moves the mailboxes of an Exchange Server organisation from source databases to target databases with migration batches — for example to empty DB01…DB09 into new databases — with an HTML and CSV report at every step.

Highlights

  • System and user mailboxes kept apart: -Workload System (arbitration, audit log, discovery: individual move requests, completed automatically) and -Workload User (user, shared, room, equipment, linked, public folder mailboxes and archives: local migration batches, completed when you decide).
  • Monitoring mailboxes never moved, checked when reading, in the plan and before each submission.
  • Plan reviewed before anything happens: target database and batch of every mailbox, balanced batches, primary-only / archive-only / both moves.
  • One mode per step: Inventory, Plan, Start, Status (-Follow), Complete (now or -CompleteAfter), Cleanup; -WhatIf sends every Exchange command with -WhatIf.
  • Only touches its own objects: never removes a move request or a batch it did not create, nor a batch whose moves are not finished.
  • Everything driven by config\ExchangeMailboxMigration.config.psd1.

Package updated on 2026-10-02

Same version, same files, no change to what the tool does: the README and the guide now start with a note to unblock the files downloaded from the Internet (Get-ChildItem "C:\Chemin\Du\Dossier" -Recurse -File -Force | Unblock-File). The Install-Module commands of the guide use -Force, with what to do when an older module version still conflicts.
