Event Log Details:-
Log Name: Application
Source: MSExchangeIS Mailbox Store
Event ID: 9877
Task Category: Content Indexing
Content Indexing function ‘CISearch::EcGetRowsetAndAccessor’ received an unusual and unexpected
error code from MSSearch.
Mailbox Database: Mailbox Database
Error Code: 0x80041606
Cause Of Issue:-
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.
Note The most common way to reach the 200,000 nodes limit is to search for
a word or phrase that contains a single digit or letter. There are also other less
common causes, such as entering very complex searches with many ANDs,
Ors, and NOTs. Additionally, complex combinations of date ranges and
search terms, many entries in the To and From fields, or a combination of all
these things may cause the limit to be reached.
