Try the following methods.

Method 1: 

Start->Start Search >  then type the following -> "Outlook.exe /resetnavpane" without the quotes.

(Look for the space between outlook.exe and /)

Method 2: 

Check if Outlook is in a compatibility mode: 
1> Open My Computer>Local Disk C>Program Files>Microsoft Office>Office 12>Outlook.exe.
(If you are using a 64 bit machine, go to C:\Program Files x86\Microsoft Office>Office 12>Outlook.exe) 

2> Right click on Outlook.exe and click on Properties and then click on Compatibility tab. Check if you have any check mark in any of the compatibility mode options. Make sure you also click on the option "change settings for all users" tab at the bottom of the same screen and look for similar check boxes in the window.
 
3> If you see any check boxes in the compatibility mode options, uncheck all the boxes and click on Apply and OK. 

4> Try to open outlook again

Hi!

This issue can be fixed by first locating Outlook.exe that can be found here: C:\Program Files (x86)\Microsoft Office\Office14.

Next, right click Outlook.exe and then click on Properties. On the Compatibility tab, clear the check box that reads ‘Run this program in compatibility mode’. Then click Ok and restart Outlook.

If you could not solve the problem, you can try to solve it in a different way, such as described here:
