Windows – Error when starting Outlook 2007 on Windows 7

microsoft-outlook-2007windows 7

Every time I start Outlook 2007 SP2 on my Windows 7 box Outlook will look like its loading fine, then I get this error message:

cannot start microsoft office outlook. cannot open the outlook window

and outlook will close. I was able to get outlook to start by using

outlook.exe /resetnavpane

in the Start->Search box, a nice tip which I got from this social.microsoft.com page. But it didn't fix the problem since outlook is still complaining when it starts after a reboot.

What can I do to get outlook to startup normally?

That error can be related to your Outlook.OST file been corrupted.

How to force Outlook to create a new .OST file:

  1. Close Outlook
  2. Make sure you are able to see file extensions
  3. Go to the folder where Outlook.OST is saved

• Windows 7/Vista: C:\users\%username%\AppData\Local\Microsoft\Outlook
• Windows XP: C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook

  1. Rename Outlook.OST to Outlook.OLD
  2. Relaunch Outlook
