I have been messing around with Microsoft Outlook 2007 today in an attempt to not only make it start quicker but also to make it run more efficiently. One area I have been concentrating on is the Trust Center where you can manage the Outlook Add-ins. The more Add-ins you can disable the better as each one th, at is disabled is one less task that Outlook has to load on start up and keep track of while running. Below I explain what the Microsoft VBA for Outlook Addin is and how to disable this and other Outlook add-ins. Make sure you understand what each add-in is before disabling it because disabling add-ins could remove Outlook functionality that you use on a regular basis. A good example of this would be if you remove the iTunes Outlook Addin you will lose the ability to sync calendars between Outlook and your iPhone so if you don’t sync the calendars between the two then it can safely be removed for a small performance gain.
