Unrecognized Database Format


The unrecognized database format error message appears when trying to open an Access database, or appears when using a current database.

Likely Cause 1

This might have happened if you attempted to open the database in an earlier version of Access (but the database was created in a later version).


You will need to convert the database to a previous version of Access, using your current version.
By converting your database you can open the database with an older version of Access. This is only possible if you you have the newer version of Access however.

Unrecognized Database Format

Likely Cause 2

The unrecognized database format error message is a commonly recognized symptom of a damaged (corrupted) database and will prevent the user from running the Compact and Repair Database option in Access.


If you have a backup then you can restore your data from the older copy. If your backup has sufficiently less data than the corrupt version then you may require the help of a professional to repair the file.
