Azure PST Import is a migration method that enables PST files stored in Azure Blob Storage to be imported directly into Exchange Online mailboxes. It follows the standard two‑step Exchange Migration Service pattern: an initial analysis phase to validate and assess PST data, followed by execution of the actual migration. The process also involves creating a migration endpoint, running an analysis-only migration batch, using the analysis results to configure the final batch, and then starting the batch to import PST content into target mailboxes.
