Couldn't open outlook Windows

My boss asked me, why his outlook couldn't be started and keep giving the error message "Couldn't open outlook Windows". Luckily I found the solution on google.

1. Just open the start menu dan type outlook /resetnavpane on the run command text box.
2. If you could'nt find the run command text box, just simply press the Windows button and R button simultaneously.

Now he can start the outlook dan running faster than ever.
