    Hi!

    Try to use -Priority High (or Emergency, if supported) parameter in your New-MailboxExportRequest cmdlets. See, if it helps to speed up export.

    Than - is export to PST performing to the server in the same subnet/site, where your Ecxhange CAS/MBX is located?

    About performance - it will processing export with maximum available for export resources, without affecting common Exchange performance.

    Hi Risingflight,

    It seems that 40G will cause a big load on your Exchange server. So, I would suggest you split the export task into two parts by ContentFilter. It will reduce the load and complete the task quickly
