i just noticed some unexpected behaviour when restoring a mailbox into a pst file. All items marked as private are not included in the PST file, when restoring via Veeam Explorer for Exchange using the Backupadmin who has full access to said mailbox. They are noted as failed in the popup message when the export finishes. Well, to be honest, my first thought was: security-feature, sounds like it should be like that by design.
Using the same Backupadmin and connecting to the mailbox via Outlook does not show any of the private items either. Again: sounds correct.
But using Outlook to export the connected user-mailbox to a PST-file DOES indeed include all private items.
So, the question is: what is the correct behaviuour there? Outlook seems to undermine privacy settings in that particular scenario. But since Veeam uses an Outlook-Client for exporting PSTs, why do those items still fail?
When restoring back to the mailbox, different credentials can be used which i guess avoids errors when restoring private items, but that is not possible for PST-exports.
Additionally: when i first noticed, the user mailbox had a massvie amount of private items, the export took ages (Veeam 9.0U2). I just read over the logs and for my understanding each private item causes a stall for several seconds.
I just tested again with a tiny test-mailbox containing several private items with 9.5, which was way faster but still failed for private items. Has performanced improved?
Any feedback is welcome.
