Cause 1: Insufficient permissions to access the database

When users upgrade their Windows server from Windows 2003 to Windows 2008 R2. They follow numerous steps as the deletion of the old ownership and permission save all the files on external HDD, creating new owners, assigning permissions to new owners, and providing full access and many more. 

But somehow even after executing these steps carefully and sincerely only the domain administrator gets access to the Microsoft Access database. So, when the other users try to view the Access DB file on the same server, they receive an error message – “Unrecognized Database Formats, database is corrupt or in an inconsistent state”.

Solution:

  • If in the case where domain admin receives the complete access rights to view the Access database on the server. Then the issues arise because of permissions on the domain or that folder where the Access database is placed. Providing complete permissions to all users on the network share will help to resolve the “Unrecognized Databases Format, the database is corrupt or in an inconsistent state”.
  • If the issue still exists, give Local Admin rights to all the users on that server.
  • At the last, check the custom permissions on the database which displays the error. 

 The domain administrator should confirm the following with the view of users accessing the Access database:

  1. Users must sign in into that domain where the Access database is placed.
  2. Users are granted local and custom admin rights to access the database, as needed.

Cause 2: With Access 2016 along with Microsoft Visual Studio 2012

A similar error appears when a user tries to access Microsoft visual Access 2016 database during working on Visual Studio 2012. The ways of events are here:

  1. The user chooses the Database source type and the Dataset database model.
  2. Software questioned which database connection to use to connect to the database. When the user taps on “New User”, and selects the Microsoft Access Database File.
  3. Next, the application checks the type of database connection to be used where the user says: “New Connection.”
  4. The user press on “New Connection” and chooses the file name – Microsoft Access Database File (OLE DB).
  5. When the filename appears, the user chooses an appropriate file – “xyz.accdb
  6. A user ensures the connection by pressing the Test Connection, which results in an error as Unrecognized database format’ C:…..\xyz.accdb

In this case, the error occurs because of the difference generated by the line provider or Microsoft Ace OLE DB version on the Line Provider.  Therefore, install the upgraded version in the Server Explorer to fix the issue in this case like Microsoft.ACE.OLEDB.4.0 is upgrade to Microsoft.ACE.OLEDB.12.0.

Solution:

  • Add a new Data source and press on Database, followed by Dataset.
  • Go to New Connection and tap on Microsoft Access Database File.
  • Choose ACCDB file.
  • Press Advanced to modify the provider’s name.
  • Hit OK to add connection Windows and Test connection and verify.

You must have Microsoft.ACE.OLEDB.12.0 and not Microsoft.Jet.OLEDB.4.0 because the earlier version is not able to identify the database in ACCDB format.

Cause 3: Opening the database with various versions, and sudden closure

  1. Saving and accessing of Access DB file with distinct version results in conflict or variance in the MS Access database because of version conflict.
  2. The sudden shutdown of the database file or system while the database is executing a backend operation results in Microsoft Access  Database Format Error. Forceful termination of the Access file results in incomplete query resolution. It causes damage to the Access database.
  3. Same as above if the system closes without finishing the “Access file saving” process,  also results in inconsistency in the Access database. It gives the error message as “Unrecognized Database Format, the database is corrupt or in an inconsistent state”.
