What is OAB file?

The OAB file extension is a text document created when the computer programs installed in Microsoft Outlook before it was switched to Microsoft Office 365. These files contain a database of addresses and phone numbers that can be used offline. The file contains the following information: names, e-mail addresses, physical addresses, phone numbers, postal or ZIP codes and an exact date of creation. If a file has been edited or saved by the user since its last creation then the information within is automatically saved with it as well.
