After an MSCM group is created, it cannot be removed within the MSCM console.
There is an enhancement request (#31450) to request that this functionality be considered for inclusion in a future MSCM release.
If this is something that you feel would be helpful to your organization as well, please take a moment to vote on enhancement request #31450 (
www.inforcommunities.com/.../iid=31450&type=2).
Thank you!
