XADM: Error -1022 When Starting the Information Store

   Event ID: 31
   Source: EDB
   Type: Error
   Category: Logging/Recovery
   Description:
   MSExchangeIS ((313) ) Unable to read the log header. Error -1022.

   Event ID: 1120
   Source: MSExchangeIS
   Type: Error
   Category: General
   Description:
   Error -1022 initializing the Microsoft Exchange Server Information Store
   database.
				

WORKAROUND

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.
