Back from a week's leave and all ready to go when I get ...

"Cannot start microsoft office outlook. Cannot open the outlook window"

 Nice error message hey:)!

I tried a pile of the obvious stuff to no avail when I finally found the following forum entry from a guy called Dan Thomas (on the third search page!)

Run outlook.exe /resetnavpane

I guess it was obvious that the error would be to do with a navigation pane on the outloook UI - for goodness sakes!

Anyway, thanks Dan - wherever you are!!!
