Outlook 2007 SP2 will force Outlook to “shutdown”
I’ve been waiting for this feature (as I’m sure most have) since Outlook was introduced. When you shut down Outlook, it never really shuts down – or takes a long, long time to do so. The Outlook.exe process just sits and eats memory for eons, it seems.
SP2 for Outlook 2007 will finally fix this (fingers crossed).
