Outlook 2011 se plante au démarrage (fenêtre principale boguée)

Comme il fonctionne en mode sans échec, voici quelques instructions :

1- Pour vérifier si vos autorisations d'utilisateur doivent être réparées, connectez-vous en tant qu'utilisateur différent.

Si ce n'est pas le cas, réparez vos permissions.

2- Il s'agit d'une version plus détaillée :

Si ça marche en mode sans échec mais pas en mode normal

    Remove Login Items. Open System Preferences > Accounts. Click on the Login Items tab. Remove items. You’ll have to test to see which one (s) is the culprit. Verify that you are running the latest updates for all applications. Some might not be Snow Leopard ready.
    Check your Fonts & delete font caches. There appears to be a widespread issue with FontBook and font substitution in 10.6. Something having to do with the fact that Snow Leopard has moved to .ttf as the preferred font library format over .dfont. Office does not need ANY of its fonts to “run.” See Font Management for details and help deleting font caches.
    Check for corrupt preferences.
        Test for corrupt Microsoft preferences. Sort for Microsoft in the User’s Library/Preferences folder.
        Test for other preference conflicts/corruption
            Go into your home folder and take the ~/Library/Preferences folder, and put all the files in there into a folder on your desktop called old_prefs. The Finder will lock up when you move them out the first time. Force quit the Finder.
            Now log out and back in, and you will see your Mac is now back to defaults.
            Test, if it works, you know its one of the preference files.
            Start with putting everything back in that starts with “com.apple” and log out/in.
            Slowly, a few preference files at a time, move the old ones back into place, and log out and back in, then test.
            Rinse and repeat until you find the bad preference.
        If the problem persists, try the same thing with the other sub-folders of ~/Library.
            ~/Library/Caches
            ~/Library/InputManagers
            ~/Library/Fonts (Office 2008 and 2011 no longer use this folder for fonts. You can delete or move to a Fonts disabled folder)
            ~/Library/PreferencePanes
            ~/Library/Application Support
            ~/Library/Application Enhancers
