CAUSE

Service Specific Error 0xc800022d is translated to JET_errMissingRestoreLogFiles.

This error message is recorded if old transaction logs exist and they are not in sequence with the restored log files. These log files are not required for hard recovery to complete. Even if the restore was successful and log files from Backup and the current log files are in sequence, the old log files prevent hard recovery.

RESOLUTION

Start Registry Editor.
Locate the following key in the registry:
HKEY_LOCAL_MACHINE\System/CurrentControlSet/Services/MSExchangeIS/Restore in Progress
Write down the values of HighLog Number and LowLog Number of the Restore in Progress key.
In the Transaction logs folder, delete all log files that are older than the LowLog Number (lower LGeneration).
Start the Information Store service.
