I need to be able to access cached address books RRS feed

  • Question

  • Outlook seems to store cached address books from Exchange in one or more files. I believe they are like 6 interrelated files all with the extension of OAB. I need to be able to extract information from these. I need a full binary spec and instructions or sample routine on how to extract address book information from these files.

  • Hi ODO_ODO,

    Currently, there is no standalone documentation for the .OAB format and there is no plan to release documentation for the OAB format in the immediate future.  However, I would like to understand your Use Case scenario and why you cannot use our published APIs to access the local OAB.

  • I have PST and OST files with associated cached address book entries in a disk volume that has been mounted on a non-Windows based system. These files are essentially now offline and I need to be able to extract whole messages from these files with associated address book information. These volumes might be mounted on a Windows system but in most cases they will be mounted on a *nix flavor of system. Windows, Office and Exchange APIs are usually not available. These files might be years old archives the content of which might be legal documents, medical documents, emails from someone on document retention, government records just to name a short list.

    Also, the forum alert mechanism is not sending me alerts from the 2 previous replies. I have subscribed to the alerts.

  • Hi ODO_ODO,

    My apology.  Upon further investigation, we do in fact have a specification document for OAB, which is [MS-OXOAB], http://msdn.microsoft.com/en-us/library/cc463914.aspx.  If you need further assistance the Exchange Protocol forum is better suited to assist, http://social.msdn.microsoft.com/Forums/en-US/os_exchangeprotocols/threads

  • Also note that there are some supporting documents for the offline address book.

    In addition to MS-OXOAB, you also might like to look at:
    MS-OXOABK (objects within the address book), which you can find at http://msdn.microsoft.com/en-us/library/cc433489.aspx
    MS-OXOABKT (user interface templates), which you find at http://msdn.microsoft.com/en-us/library/cc433477.aspx
