Event ID: 9877
Task Category: Content Indexing
Content Indexing function 'CISearch::EcGetRowsetAndA
ccessor' received an unusual and unexpected error code from MSSearch.
Mailbox Database: MBX01-Primary
Error Code: 0x80041606
This issue occurs because Exchange Search has a hard-coded prefix search limit of 200,000 nodes for a single character search. When a prefix search exceeds this limit, the search returns QUERY_E_TOOCOMPLEX. Therefore,0x80041606 is logged as part of event ID 9877. By default, all searches that use Outlook online mode in an Exchange 2010 environment are prefix searches. Using single digits or letters causes the system to search for all numbers or words that begins with the single digit or letter across the whole mailbox database. If the 200,000 nodes default limit is reached, the search returns the error.
Since the database CI is already reset few times but still no progress
