Symptoms
Consider the following scenario:
-
You perform Multi-Mailbox Search in a Microsoft Exchange Server 2010 environment.
-
You specify multiple users in the Message To or From Specific E-Mail Addresses option.
In this scenario, Multi-Mailbox Search fails. Additionally, you receive the following error message:
An error occurred when searching Mailbox. The message is 'Search Failed on mailbox 'Domain\Mailbox\ID'. If the search query used short words with wildcard(s) such as pat*, it can result in a large number of words or phrases because all permutations of words starting with “pat” are searched. Make search queries as specific as possible when using wildcards. '.
Additionally, following event is logged in Application log on the Exchange Server 2010 server:
