Error: Couldn’t find unique request with the provided information when get-mailboxexportrequest

Scenario: When running a get-mailboxexportrequest (or get-mailboximportrequest, remove-mailboxexportrequest, or remove-mailboximportrequest) you get the following error:

Couldn’t find a unique request with the provided information.

This is a result of running two separate mailbox export requests on the same mailbox, and Exchange didn’t create a unique name for each of the export request jobs. Therefore it creates a duplicate entry and Exchange hates you — just kidding.

Solution: If you need to cancel a duplicate export or import request, you can use the RequestGUID and RequestQueue to help identify the unique entry of a duplicate request, a true oxymoron.

get-mailboxexportrequest | Select Identity, name, RequestGuid, RequestQueue

Remove-mailboxexportrequest -RequestGuid xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -RequestQueue DBxxxx
