FAQ · Microsoft Access support

What causes Microsoft Access database corruption?

Common causes include network interruptions, multiple users sharing one front end, forced shutdowns, unstable storage, file-size pressure, faulty hardware, and application errors during writes.

Short answer

Common causes include network interruptions, multiple users sharing one front end, forced shutdowns, unstable storage, file-size pressure, faulty hardware, and application errors during writes.

What this means in practice

Corruption risk is reduced through architecture and operating discipline rather than relying only on Compact and Repair.

Give every user a local front end.
Keep the back end on reliable supported storage.
Avoid opening Access data files directly across unstable VPN connections.
Maintain automated, tested backups.
Close objects and database connections cleanly in VBA.
Monitor the database before it approaches the 2 GB file limit.

The practical next step

If corruption happens repeatedly, treat it as a system-design warning. A server database can provide stronger transaction handling and recovery while preserving much of the existing Access application.

This answer provides general guidance. The right recommendation depends on your application, data, users, licensing, and business requirements.
