Hi, my Outlook will not open after downloading and running the latest service packs yesterday. Outlook opens into a tiny window, first it said Microsoft SEtup Bootstrapper is not working, now it only opens in a tiny window and then closes saying, cant open Outlook. Tried uninstallating service packs through windows updates, but no different, any ideas please.

Hi There

Provided you are using a valid(licensed) version of windows the best thing to do would be to backup your data using free backup software i recommend DMailer Backup from then reinstall windows.

Good Luck

Hi Thanks, it is all legal software, the answer lay as follows;

Start Outlook with the resetnavpane switch;
Start-> Run; outlook.exe /resetnavpane
(note the space in the command)
