Outlook 2016 Export to PST Missing a Lot of Data
-
@scottalanmiller Unfortunately, there is no "User interface" apart from the admin interface, but there is not a lot to the program except for having a local repo, connecting O365, selecting the user along with a couple of other requirements and hitting start.

We have an Office 365 account with Outlook 2016 attached and we need to archive the entirety of a mailbox to a PST file. When we do so, the PST is very large, 8GB or bigger. And it gets some stuff. But loads of emails are missing, too.
Outlook is configured to download all, not headers or anything like that. Cached Mode is on, and retention set to all. Slow link detection is off. Folders have been updated.
And yet still, we can go into a folder in the Inbox, and it still says "Click here to download more from Exchange" or whatever. If we click that, email shows up. Navigate away and back, and it is black again. Export it, and it is blank.
How can you get Outlook to get all of the email, not just some?
On-premises we'd run the Export-Mailbox PoSh in the Exchange Console. Is there an ability to do that in O365 (all of our hosted mailboxes are third party)?
Another option would be a MAPI sync tool that could do a full pull. EDIT: Veeam is da bomb. :0)

Yes, we would, too. We looked into that command. And the answer is "no", O365 doesn't allow that to be run

Yeah, that seems like the best answer.

Have you tried deleting/clearing out the local cache/.OST file, then letting it rebuild, then export to PST?

Install Veeam's O365v2 backup to a repository. Free for up to 10 users
I wasn't aware that they had a free options. Thanks for bringing this to my attention!

That BitTitan product that I ended up using for my migration was da bomb. Maybe check them out as well.

You can right-click on the mailbox, or a folder, and in properties, you can see how much data is there versus on the Exchange server.
Most is there, for sure. But definitely not "all".
Confirm. I got always this end result. This is just best effort. Not complete at all.

That's just crappy, especially as Microsoft themselves recommend it.
