[Solved] "Unrecognized database format" MS Access 2007 Win 7

Postby miasma.gajs » Wed May 06, 2015 11:30 pm

Have been using Base to run queries against an MS Access 2007 database (.accdb) on XP. Moving to Windows 7 Pro SP1 and having problems connecting to the accdb. I have read this thread and done everything there (I believe!) but still encounter the above error message.

This happens whether I try to connect using the original Base (.odb) or create a new odb.

Any help much appreciated.

Well, sometimes the easiest explanation is the simplest... I, or Bill Gates, had managed to corrupt the accdb. Fixed and all working now. Sorry for the red herring.

There are multiple causes for ‘unrecognized database format’ error which are:
1. Inadequate permissions to access the database
• In case if the domain admin with full access rights can open the Access database on the server, the issue is due to permissions on the domain or that folder where the Access database is located. Granting full permissions to all users on the network share may help resolve the “Unrecognized Database Format, the database is corrupt or in an inconsistent state”.
• If the issue is still not resolved, assign Local Admin rights to all the users on that server.
• Lastly, check the custom permissions on the database which displays the ‘unrecognized database format’ error.
2. Opening the database in different versions, and abrupt closure
Inaccessible Access database may result in corruption, which can be resolved with the help of Compact and database Repair Utility provided by Microsoft
