Posted on Posted in Exchange Server, Outlook

 

This blog will guide you how you can export Exchange 2010, 2013 and 2016 mailbox to PST using PowerShell cmdlet New-MailboxExportRequest.

Mainly users export exchange mailbox i.e. EDB files to PST files for archiving because PST is the best way to store the email locally as a Backup. Also, for security compliance and when moving mailbox to another location (between exchange database).

Export Exchange mailboxes to PST file

To export or import you need to assign rights because by default, no exchange user can export or import Mailboxes to or from PST files. As part of the Role Based Access Control (RBAC) in Exchange 2016 there’s the Mailbox Import Export role, but this role isn’t assigned to any account/user or Security Group. This can be easily done by adding Mailbox Import Export role to the user or simply you can add the user/account to a security group with this right.

By using Exchange Management Shell cmdlets, Exchange users can convert EDB files to PST format easily, only needs permissions to do so. However, In Exchange Server 2013, apart from the cmdlets, Exchange Admin Center (EAC) can be used to perform the export action.
