SYMPTOMS
If the computer running Microsoft Exchange Server stops responding or is not shut down gracefully after stopping all the services properly, the following error message may appear on screen and in the event logs:

Error -550 has occurred

This message may also appear when you start the directory or information store service, in case of a power failure.



CAUSE
This error usually means that the database is in an inconsistent state and cannot start.

NOTE: This problem usually occurs when users move or delete their log files or database. If the log files are deleted or moved, recovery appears to work (no log files = no recovery), but the database will be inconsistent. If the database is moved, recovery will not work (the path to the database is hard-coded in the log files). If the log files are moved without updating the registry, recovery will not work.



RESOLUTION
Confirm that the state of the database is inconsistent, and then try a defragmentation repair. Be sure to stop all services and back up all files before you run the Edbutil.exe program.   Check the state of the database.

Versions 4.0 and 5.0
Use Edbutil.exe with the "MH" option on the problem database, and dump the output to a text file:

EDBUTIL /MH c:\exchsrvr\dsadata\dir.edb >c:\edbdump.txt

-OR-

EDBUTIL /MH c:\exchsrvr\mdbdata\priv.edb >c:\edbdump.txt

-OR-

EDBUTIL /MH c:\exchsrvr\mdbdata\pub.edb >c:\edbdump.txt

Version 5.5
Use Eseutil.exe with the "MH" option on the problem database, and dump the output to a text file:

ESEUTIL /MH c:\exchsrvr\dsadata\dir.edb >c:\edbdump.txt

-OR-

ESEUTIL /MH c:\exchsrvr\mdbdata\priv.edb >c:\edbdump.txt

-OR-

ESEUTIL /MH c:\exchsrvr\mdbdata\pub.edb >c:\edbdump.txt

 Edit the Edbdump.txt file and confirm that the state of the database is inconsistent.  If the database is inconsistent, run the following commands:

Versions 4.0 and 5.0
EDBUTIL /R /DS

Version 5.5
ESEUTIL /R /DS

Use EDBUTIL /IS or ESEUTIL /IS to recover the Priv.edb and Pub.edb files. They both use the same log files, so they will be recovered together.
