    I am facing the above problem when I open Outlook

    "Unable to open your default e-mail folders. You must connect to your Microsoft Exchange Server computer with the current profile before you can syncronize your folders with your offline folder file."


    I have tried to remove the profile and re-create it. The check mark in the Security to Encrypt Microsoft Exchange is there.

    The only resoltuion to it is to reinstall the whole Outlook which when I do, the issue is resolved however that is not the ultimate solution as i work in a Banking company and face this issue every now and then. Can anyone help me find the actual root cause of the issue.

    Thank You.

    You should try the Integrity check tool, also known as scanost.exe. It's a freeware utility provided by Microsoft. It can scan corrupt OST file and fix it. Refer to this blog post to know how to use scanost.exe - Use scanost.exe (Integrity Check tool) to Repair OST File

    Remember there's no need to use to any commercialware tool. Hope scanost.exe works here.

    If you want to restore OST files and don't want to spend money, you must try few add-on applications of Outlook client. You can use any of these features: Inbox Repair tool (ScanPST) or OST Integrity Checker (Scanost.exe). ScanPST and ScanOST utility provided by Microsoft and installed in mostly Microsoft Office version. First, Find out the OST file location

    Windows 7 and Windows Vista: drive:\Usersuser\App\Data\Local\Microsoft\Outlook

    Windows XP: drive:\documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook

    ScanPst.exe to scan and repair only a corrupted Outlook Personal folders (PST) file or an Offline Outlook Folder (OST) file, not your mailbox on the server. The utility determines whether the file structure is unscathed. If it is not unscathed, the ScanPst.exe resets your file your file structure and rebuilds the headers. Find the scanpst.exe location according to your Outlook version and Windows version (32 or 64bit):

    Outlook 2013 (32bit) & Windows (32bit): Drive:\Program Files\Microsoft Office\Office15
    Outlook 2013 (32bit) & Windows (64bit): Drive:\Program Files (x86)\Microsoft Office\Office15
    Outlook 2013 (64bit) & Windows (64bit): Drive:\Program Files\Microsoft Office\Office15

    Outlook 2010 (32bit) & Windows (32bit): Drive:\Program Files\Microsoft Office\Office14
    Outlook 2010 (32bit) & Windows (64bit): Drive:\Program Files (x86)\Microsoft Office\Office14
    Outlook 2010 (64bit) & Windows (64bit): Drive:\Program Files\Microsoft Office\Office14

    Outlook 2007 & Windows (32bit): Drive:\Program Files\Microsoft Office\Office12
    Outlook 2007 & Windows (64bit): Drive:\Program Files (x86)\Microsoft Office\Office12
