If for some reason, you decide to uninstall CRM, you need to take into consideration any workstations that may have the Outlook Client installed.

Before you uninstall the CRM server, run the Rule Deployment Wizard and remove the CRM Rule from Outlook for each deployed user.

In the case of CRM Small Business Edition, the Uninstall will remove the CRM mailbox.

CRM Professional will produce different results because, in many cases, the CRM Server and the Exchange Server are on different computers and the Uninstall of CRM will not affect the Exchange Forwarding service.

Removing the Rule is important because if you don't, it will attempt to forward email to the now non-existent CRM Mailbox which will cause the user to receive a bounce email any time they get an email that may have the CRM Tracking Token in the subject.
