New-MailboxExportRequest (ExchangePowerShell)

You can create more than one mailbox export request per mailbox, and each mailbox export request must have a unique name. Microsoft Exchange automatically generates up to 10 unique names for a mailbox export request. However, to create more than 10 export requests for a mailbox, you need to specify a unique name when creating the export request. You can remove existing export requests with the Remove-MailboxExportRequest cmdlet before starting a new request with the default request name <alias>\MailboxExportX (where X = 0-9). You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet. You need to grant the following permission to the group Exchange Trusted Subsystem to the network share where you want to export or import PST files: To import PST files from the share: Read permission To save exported PST files to the share: Read/Write permission. If you don't grant this permission, you get an error message stating that Exchange is unable to establish a connection to the PST file on the network share.
