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!

    I’m running exchange2007.

    I have a user that is on the domain, with a email account already on outlook and I’m trying to add his email through our company on outlook and I’m getting the following errors, “cannot start microsoft office outlook. cannot open the outlook window. The set of folders cannot be opened. The information store could not be opened.”

    I tried doing outlook.exe /resetnavpane
    I’ve tried deleting all .xml files (c:\users\username\appdata\roaming\microsoft\outlook)
    I’ve used PSTSCAN and OST Scan on each PST/OST file to no avail.

    I actually took out a spare computer that we just recieved but haven’t allocated to anyone and put in the same emails and it worked just fine(the second computer had Exchange2010).

    The email is setup as Pop3 and of course I’m trying to setup my email as a regular exchange account.
    I did try setting it up as a Pop3 acct as well to no avail; as well as, connecting it through our webmail. Our webmail is setup as https not http though. I know that was an issue in previous versions but wasn’t sure if that was still the case.

    Any help with this issue would be greatly appreciated.

    you can try to perform a quick repair the existing office installation.
    I don’t recommend an online installation as it may reset the activation settings.
    for more understanding, I hope the below link should be useful for you.
