To enhance the functionality of MS Access, Microsoft introduced a new database file format ".accdb" with the release of MS Access 2007.

Few common factors responsible for corruption of .accdb file are application malfunction, unexpected system shutdown, and virus hits. Once the .accdb file gets corrupted, the data stored in the file becomes inaccessible. An ideal way to overcome .accdb corruption scenarios is by restoring the .accdb file from an updated backup. But if in case, you have not maintained any backup or backup falls short to restored the desired records, then you will need to opt for advanced access repair application.

Consider a practical case, where you encounter the below error message when you attempt to open your .accdb file:
