Most home and personal accounts do not use Microsoft Exchange and it is only the big corporations that usually use Outlook. If you don’t use Outlook as part of a corporation as well, you don’t need Microsoft Exchange Unified Messaging. Here’s how to
remove Exchange from Outlook 2007.
Home and Personal account users generally use Outlook with a POP or IMAP account. If you are using Outlook at home or elsewhere with a POP or IMAP account, and don’t use Microsoft Exchange, your version of Outlook 2007 may be using unnecessary system resources and RAM by running Microsoft Exchange Unified Messaging.
Microsoft Exchange is a corporate email server, and rarely used by personal and home users. If you don’t use Exchange, there’s no need to run that service inside Outlook 2007. Fortunately, it is pretty easy to remove Exchange from Outlook 2007 and free up resources to make your computer run faster by freeing up whatever resources were consumed in running Exchange unnecessarily.
Follow these steps to remove Exchange from Outlook 2007:
Select Tools→Trust Center→Add-Ins.
At the bottom of the page, select COM Add-ins from the drop-down list, and click Go.
Uncheck the box next to Microsoft Exchange Unified Messaging, and click OK to disable it.
If you instead want to remove Microsoft Exchange Unified Messaging from your system, highlight it, and click Remove.
When you exit Outlook and restart, it should be disabled.
You’d be better off first disabling Microsoft Exchange rather than removing it. Disable Microsoft Exchange Unified Messaging and run Outlook for several days with it disabled before you decide to remove it. If you have problems with Outlook, you can enable Microsoft Exchange by following the same steps mentioned above and checking the box next to it.
