Searching Microsoft Access Database Files is only available in Professional and Enterprise Editions.

When a Microsoft Access Database file has sensitive identity match information in it and you wish to keep the file on your computer, you should utilize the Secure feature to automate the securing of the file. Based on the type and version of the Access file, the secure button will have different effects.
For Access 97-2007 files, you will have the option to encrypt the files with the password you specify.
For Access 2.0 and 95 files, you will have the option to secure the files inside a compressed zip file.
For any Access file that was protected with a password, but not encrypted - Identity Finder may still have been able to find identity matches in these files. Because they are already password protected, you will have the option to secure the files inside a compressed zip file. If you have Office 2007, it is recommended that you open these password protected Access files with Microsoft Access, enter your password, and then apply encryption rather than just password protection. If you do not have Office 2007, it is recommended that you open these files with Microsoft Access, remove their password, search them again with Identity Finder, and then secure them with Identity Finder.
There are two ways to secure a single Microsoft Access Database file:
Single click the file result with the left mouse button to highlight it and click the "Secure" button on the Main ribbon.
Single click the file result with the right mouse button to highlight it and bring up a context menu, then highlight and left-click on "Secure."
To secure multiple access databases at one time, check the checkbox of each file and then choose one of the methods described above to begin securing the files. After clicking Secure, a dialog box will open with your available options.

Enter a password to secure the file(s), and click OK. If you click Cancel, no files will be secured. If you click OK and multiple files were selected via their checkboxes, the password you provided will be applied to each file. After clicking OK, Identity Finder will secure each file and remove its result row from the Results View allowing you to continue dealing with other, insecure identity matches.
You are also given the option to "Securely store this password in your Password Vault". If you do, the location and password will be saved securely within the Password Vault for you to reference later. Only you have access to your Password Vault because it is only accessible if you authenticate to Identity Finder and load your Personal Information File.
Next time you try to open the file in Microsoft Access Database, Access will prompt you for the password you entered via Identity Finder. If you forget your password, you will not be able to open your file.
Note: Choose a strong password to be sure your document is safe.
