ElephantsConfirm the intended scope
Verify the selected users, folders, time range and source-to-destination mappings. An accurate result for the wrong scope is still an unsuccessful project outcome.
Review counts and exceptions
Compare discovered and processed work, then separate transferred, skipped and failed items. Investigate patterns by user, folder, size, item type or provider error instead of relying only on a tenant-wide percentage.
Sample destination mailboxes
Inspect representative destinations for folder placement, readable messages, sender and recipient data, timestamps and attachments. Test large and unusual mailboxes as well as ordinary users.
Run latest changes and approve
After the main batch, process eligible latest changes, document unresolved limitations and obtain acceptance from the project owner. Preserve the reconciliation report with the migration record.
