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

The technical issues surrounding the Navigation Pane can be found at Microsoft's Support site KB2022778.

Have you tried safe mode?

a) Hold Ctrl and click Outlook from start menu


b) "Outlook.exe /safe" from command prompt

Yep I tried that but it came up with the same thing. I managed to sort it. Thanks anyway – Dean Perry Jun 9 '10 at 13:49

Have sorted it. Changed the .pst in Control Panel > Mail and created a new default pst file and it seems to be working fine for some reason.

  4. Set new outlook again

You can try to perform a quick repair for the existing office installation.

I don't recommend an online installation as it may reset the activation settings.

For more understanding, I hope this link is useful for you.

Welcome to Super User! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – ᔕᖺᘎᕊ Jul 15 '14 at 10:57
And, the link you use is talking about Office 2010+, are the instructions the same for Office 2007?? – ᔕᖺᘎᕊ Jul 15 '14 at 10:59
