“Unexpected error 25012” Causes Database Corruption in Microsoft Access

Microsoft Access is a widely used database management system, which is the part of Microsoft Office suite of products, developed and marketed by Microsoft Corporation. Access stores all your significant data in the form of database, which is stored in MDB (Microsoft Access 2003 and earlier) and AccDB (Microsoft Office Access 2007) file formats. It is made up of several objects, which are assigned different tasks and work together to store and organize your data. The MS Access database objects are managed and controlled by Jet Database Engine. In case any of the database objects get damaged or become inaccessible, you may lose access to your database and come across critical database corruption situations. In such cases, you must repair Access database to extract data from it.
Sometimes when you try to open an Access database (either MDB or AccDB), the process fails and you come across the underwritten error message:

“Unexpected error 35012”

After this behavior, you cannot access the database and stored data from it. It leads to critical data loss situations. To gain access of your database in such cases, you need to find out the root of this issue and then perform Access database recovery by resolving it.

What causes 'Unexpected error 35012' in Microsoft Access?

This behavior occurs if one or more of the Microsoft Access database are corrupted. The most significant objects of Microsoft Access database include tables, reports, forms, macros, stored procedure, triggers, constraints, and more.

Access database objects may get damaged due to various reasons, such as virus infection, improper system shutdown, application malfunction, file system errors, operating system corruption, file header corruption, and Jet database engine errors.

How to fix 'Unexpected error 35012' in Microsoft Access?

Go through the below steps to sort out this issue:
  • Create new Access database.
  • Point to 'Get External Data' on File menu, and click Import.
  • Exclude the corrupted objects while importing and restore them from backup.
If the above method cannot resolve your problem or you do not have a good backup, MDB recovery becomes need of hour. It is best possible using commercial database repair applications.
Access recovery software are particularly designed to scan whole database and restore all corrupted objects from it. They are incorporated with interactive and simple graphical user interface to offer easy recovery in all database corruption scenarios.
