New hire brought a 4GB PST from her previous job and wants it inside her Exchange mailbox rather than as a side archive. Exchange 2016 on-prem. Cleanest way to inject it?

Mirror of the export flow. Grant yourself the Mailbox Import Export role if you have not already, put the PST on a UNC share, then run New-MailboxImportRequest -Mailbox her.alias -FilePath \\server\share\old-job.pst.

Add -TargetRootFolder "Previous Job" so 4GB of foreign mail lands in its own folder instead of flooding her inbox. Watch progress with Get-MailboxImportRequest.

Imported into a Previous Job folder exactly as suggested. Tidy result. Solved.
