Exporting Exchange mailboxes to PST is a necessity that each administrator needs to perform routinely. When the size of mailboxes increases, then they become less responsive and slower. Also, there are multiple requirements for an Exchange mailbox backup-
Compliance requirements – You can export mailbox for legal retention purposes. The PST file is saved for future purposes like litigation.
Backup needs – If you want to take the backup of only a few mailboxes without saving others, then the export option allows you to choose an individual mailbox selectively.
Suppose, being an Exchange administrator, the user has decided to export some Exchange mailboxes to Outlook PST format. This can be done using the New-MailboxExportRequest command in the Exchange Management Shell –
Now everything is looking fine with the command after the user has entered the mailbox username, and the network shared path of the PST file folder. Still, the user has encountered an error as below:
The error in brief states that “Object couldn’t be found on the primary domain”.
Note: The same error can be encountered even if the Exchange administrator has performed the Exchange mailbox export using the Exchange Admin Center interface.
Knowing the reason behind the error is necessary to resolve it. We suggest the Exchange administrator try these troubleshooting methods:
Once all the pre-requisites of the New-MailboxExportRequest are met, you can try exporting mailboxes again.
So, add the Domain controller switch to the mailbox export command specifying the domain controller in which the user mailbox exists.
Now, the export command would be:
So, simply adding a Domain Controller switch to your Mailbox export command in the Exchange Management Shell would help you resolve the error problem.
Using Exchange Management Shell certainly requires expertise. There are chances of errors even if you are a pro.
If you are ready to go for an alternative for exporting Exchange mailboxes, which is simpler and less error-prone than the conventional process, then try a professional solution to export Exchange mailboxes.
Exchange mailboxes can be exported directly from the Exchange database to Outlook PST file without any complex commands. An easy method to do that is through a reliable professional tool, Kernel for Exchange Server.
Exchange Recovery tool not only repairs corrupt offline EDB files, but also supports mailbox export to Outlook PST file format. It converts EDB mailboxes to PST files and allows moving only desired data (with smart filters) after previewing the mailboxes items. Users can move mailboxes from offline EDB file of all Exchange Server versions (even older than Exchange 2010) to PST and destinations such as live Exchange, Microsoft 365 and Outlook profiles.
Sometimes, Exchange administrators may face the error ‘Object couldn’t be found on the primary domain’ while exporting mailboxes to PST. This Exchange error that occurs due to a different domain controller can be fixed by the introduction of a domain controller switch in the New-MailboxExportRequest command.
