Possible Reasons behind Access Database Corruption
- Over time, an Access database can become bloated. This happens as more and more data get stored in the database, increasing its size and corruption risk.
- When an Access database is shared over a network, and your connection is broken, the database may get damage.
- An Access database may turn corrupt if the database, computer, or server holding linked tables is restarted.
Quick Troubleshooting Tips to Fix an Access Database
Problems with an Access database can sometimes get fixed by following these troubleshooting tips:
- Close your database and restart it.
- Open your Windows Task Manager and ensure all instances of Access are closed.
- Update your MS Office program manually to the latest release to receive bug fixes that might be preventing your Access database from opening or causing it to work unexpectedly.
- Try opening your Access DB on another PC.
- Check your database file size. Often, large size of the file may corrupt the database. In that case, compressing the file or splitting the Access database might help resolve the issue.
- Create a new blank Access database file and import objects from the corrupted file in the new file.
