2. If you initialize an incompatible EDB file, the process checks whether that log range defined in database header is there in directory of log, and signatures of both log and database are right. In case it does not locate the specific values, it logs the underneath event:

"JET_errRequiredLogFilesMissing (-543)"

3.The database may also face logical corruption if you run eseutil /p utility. Jet-level Exchange Server database repairs outcome in some disorganized disk space uses and data loss, as it fixes the EDB file by removing the corrupt data.
