Resolving Error Message ““Microsoft database jet engine is unable…” in MS Access

In a multi user environment, every user has certain rights that allow him to use the database. Corruption of Microsoft Access database in a multi user environment can occur at any client end. Once the database is corrupted, it becomes inaccessible and displays an error message as per the issue. To overcome such data loss situations, the best option is to restore it from an up-to-date backup. However, if no backup is available or backup fails to restore the required information, you need to opt for advanced Access Database Repair.

As a practical instance, you ran a query to view all the records in the Employees table. While the query was extracting the records, system shuts down due to power failure. When you restart your system and attempt to remount the database, you encounter the below error message:

“Microsoft database jet engine is unable to find the object ‘msysdb’”

The data stored in the database becomes inaccessible after occurrence of the above error message. In addition, you encounter the same error message each time you attempt to mount the database.

The root cause behind the above error message is corruption of Microsoft Access database due to improper shutdown.


To resolve the above error message and use the data stored in the database, you need to apply an inbuilt repair utility known as “Compact and Repair.” To use the utility, you should follow these steps:

1.Go to the Tools menu, select Database Utilities and then click Compact and Repair Database.
2.Locate and then click the database in the ‘Database to Compact From’ dialog box, and then click Compact.
3.Select an appropriate folder location for the new file in the ‘Compact Database Into’ dialog box, type a unique name for the file and then click on the Save button.

However, if the inbuilt repair utility fails to repair the Access database, then you need to use efficient Access Repair tools. Such access database repair utilities employ effective scanning algorithms to entirely repair and restore all Access database objects. These tools can easily recover and restore inaccessible Access (.accdb and .mdb) database files. With highly graphical and interactive user interface, these recovery tools are easy-to-understand and implement.

Stellar Phoenix access recovery is the foremost Access Database Repair utility. The software can restore and repair database objects like queries, forms, reports, macros and modules. It supports Microsoft Access 2007, 2003, XP (2002) and 2000. This Database Repair Software is compatible with Windows Vista, XP, 2003, 2000 and NT.
