Outlook 2007 - Cannot start Outlook - Cannot open the Outlook window

I went to open Outlook 2007 on my Windows 7 32bit machine and it came up with this error:

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 have deleted and created a new profile in Control Panel > Mail but it still doesn't want to work properly but it still comes up with this message.

Thanks in advance.

Just had it happen to me this morning. (Win7 x64, Outlook 2007). The message can be caused by a number of issues like a compatibility setting or a corrupted outlook profile file. In my case, I had to run the following at a command prompt:

Outlook.exe /resetnavpane
