I'm having the same problem: Cannot Open Microsoft Office Outlook.
But the solution that is offered, outlook.exe/resetnavpane, isn't working. When I do Start--Run and type that in, and press OK, I get another message saying "Windows cannot find 'outlook/resetnavpane'. Make sure you typed the name correctly, and then try again."
I also tried outlook/resetnavpane.
Should there be quotes or double quotes around it? Should there be a space before and after the /? I tried many permutations with no success.
Weirdly, this happened to me a few months ago and this solutio worked?
I'm running Windows 7 x64.
Thanks in advance.
