  1. Don't Do This says:

    Beware – these instructions would screw up any existing installations of SQL or CRM as well. It's pretty reckless to post such broad, sweeping instructions for the removal of a fairly small product. It's like using a nuclear missile to kill a fly.

  2. DO This says:

    if you are trying to upgrade CRM to a newer version Using tools like SCCM.  The HKCU CRM registry keys must be elimnated prior to luanching outlook for the first time withthhe updated CRM.  CRM will not auto configure to a new CRM server with these keys present from the older installation.  You may need a script to parse thru all user hive to remove these keys if using SCCM.

  3. Definitely do this! says:

    Most users, at least at my organization, don't have additional SQL Server usage requirements. If I was removing this from a developer or BI analyst's machine, I would have to find a way around the uninstall/reinstall issues related to SQL Server. Luckily, we don't require anyone with this type of need to install CRM for Outlook.
