Cannot start Microsoft Office Outlook. Cannot Open the Outlook Window

I recently came across this problem on a customer’s computer and tried everything I could find via Google.  Naturally, none of the solutions worked.  When you click on the icon to start Outlook, the window shows up briefly and then disappears, popping up that extremely meaningful message:  Cannot Start Microsoft Office Outlook.  Cannot Open the Outlook Window .

If you google this problem, one of the first sites that shows up with a solution is Microsoft’s site, so you assume that the solution must be a good one.  Actually, it didn’t work for me.  The Microsoft page is this one.  The solutions that they give probably work in many cases, but I tried both of their solutions and I was still at the starting line.

The solution? simply run:  outlook.exe /resetnavpane

basically, this is the same as deleting your profilename.xml in your user directory.  It did the trick for me and if I can save someone the trouble of looking for that solution for hours.. then I’m happy!

    Cannot start Microsoft Office Outlook, Unable to open the Outlook window. The set of folders could not be opened. Errors have been detected in the file
    C:\users\windows7\AppData\Local\Microsoft\Outlook\Outlook.pst.
    Quit outlook and all mail-enabled applications, and then use the inbox repair tool (Scanpst.exe) to diagnose and repair errors in the file.

    For what it’s worth, this solution didn’t work for me, but I did find one that did (this time… as opposed to attempts in previous years…)

    I had to run the scanpst.exe.

    Hi

    I am still looking for a permanent solution to the problem.

    I have the additional issue that resetnavpane cleans out my Favourites and I have to recreate them each time.

    If I use /cleanviews instead of /resetnavpane. The program starts properly and crucially the favourites are not removed.

    The only issue I now have is how to get the shortcut working properly.

    I have dragged the programme file from Office 14 to the desktop and told it to create the shortcut.

    I then add the /cleanviews switch BUT the shortcut doesn’t work. It does, however, work from the run command.

    Is there a way I can insert the details into the run command as either a shortcut or a macro?

    Regards

    David

  19. please I tried but I still continue to have the same message with office 2010. Can you help me further?

  20. If the above solution does not work then try the following stes

    Close Outlook completely.
    Click Start.
    Open Control Panel.
    Category View: Click User Accounts > Mail icon
    Classic View: Click Mail
    Click E-mail accounts.
    Click to highlight “Oracle Beehive Extensions for Outlook”.
    Click Change.
    Click More Settings.
    Select Administration.
    Verify only “Personal workspace” Task is checked.
    Uncheck any other Tasks that are checked.
    Click Reset.
    Verify “Backup your personal folders when they are reset” is checked.
    Click Yes.
    Click OK.
    Click Next.
    Click Close.
    Click Close.

    Thanks,
    Prabhu
