In a Microsoft Exchange Server 2010 Service Pack 1 (SP1) environment, you use Outlook Web App (OWA) to search for items by using Advanced Query Syntax (AQS). The search contains the keyword Sent or Received. For example, you type Sent:Yesterday and start the AQS search. In this scenario, no item returns, and you receive the following error message:
The action couldn't be completed. Please try again.
This issue occurs because the Exchange Search service disables indexing of the mailbox database for AQS queries that contains the keyword Sent or Received in OWA.
To resolve this issue, install the following update rollup:
