Rename the Edb.chk file in the Exchsrver\Mdbdata folder. Try starting
the Information Store service again.
The following events should be generated in the event log:
Event ID: 18
Source: EDB
Type: Information
Category: Logging/Recovery
Description:
MSExchangeIS ((137) ) The database is running recovery steps.
Event ID: 71
Source: EDB
Type: Information
Category: Logging/Recovery
Description:
MSExchangeIS ((137) ) Redoing log file d:\exchsrvr\MDBDATA\edb00004.log.
Event ID: 71
Source: EDB
Type: Information
Category: Logging/Recovery
Description:
MSExchangeIS ((137) ) Redoing log file d:\exchsrvr\MDBDATA\edb00005.log.
The above event indicates which log files have been successfully replayed.
In the above example, edb00005.log was successfully replayed. Therefore,
the problem exists in the edb00006.log file.
If there are no Event ID 71 messages generated, the problem may be in the
Edb.log file, in which case the resolution is to move all the log files out
of the MDBDATA directory and then restart the Microsoft Information Store
service.
