PST generated from Exchange 2019 failing to import in Outlook

bcnet

Hi,
When i export a PST from MS Exchange 2019 server either through ECP or PowerShell and then i try to import it through Outlook on a mailbox hosted on Grommunio it will import few thousand of emails and then it throw the error : "Cannot move items. They were either moved, deleted or access was denied."

When i try to import again, it will run through either 1024 items or 512 items and then spit out again the previous error
If i do the PST export through the user Outlook and then import then it's fine, no error

It's only happening with PST exported through Exchange

Does anyone have an idea what could be the problem ?

Haven't heard of such problems but you might also try to import the .pst directly on the grommunio system.

And for anything else i would look through the switches for New-MailboxExportRequest even tho i haven't seen anything useful from a quick peek just now :<. Or look into the Get-MailboxExportRequestStatistics if there is something useful..
