If you have an Exchange Server database file (Priv.edb, Pub.edb, or Dir.edb) from Exchange Server 4.0 or 5.0, you can use the ESEUTIL utility to manually upgrade the database to an Exchange Server 5.5 database. This is particularly useful if the only good backup you have for your Exchange Server computer is from a previous version of Exchange Server.
In order to perform the upgrade using ESEUTIL, you will need the following files:
ESEUTIL /u <database name> /dEDB.DLLwhere the <database name> is either Priv.edb, Pub.edb, or Dir.edb.
*NOTE: There is no space after the /d switch.
**NOTE: If you do not use the correct version of Edb.dll, you will receive the following error:
Error -1003 (0xfffffc15) = JET_errInvalidParameter
