When I first installed Microsoft Outlook 2007 on my new Windows 7 laptop I had some issues with it crashing. At first I was unable to locate the issue but eventually I received the below error which pointed to the Microsoft Outlook Mobile Service add-in or OMS as it is also called. While I never did have any OMS accounts configured the add-in was loading every time that Microsoft Outlook 2007 started thus taking resources and opening the door for error. This add-in is just another service that Microsoft assumes you want and/or need with fairly little documentation available for installing, uninstalling, or reinstalling. Below I describe the error I received, another error that could appear that can be related, and how to remove the add-in from loading ever time Outlook 2007 starts.
