We just recently migrated from Exchange 2010 to 2016. In addition to our user mailboxes we also migrated a couple dozen conference room mailboxes or resource mailboxes as they are referred to in Exchange 2016.

vSphere 5 - Can not power on a VM Go to the VM cluster, right click then select Edit Settings. Click on vSphere HA. You will then see Admission Control and Admission Control Policy. Admission Control is either set to Enable or Disable. If it’s set to Enable you will not be able to power on a vm if they are not enough resources for HA according to your Admission Control Policy. You need enough a available resources, memory, cpu, and hard disk, to vMotion your vm from a failed host. If you have 3 hosts and your policy is set to “Host Failures the cluster tolerates: 1” the your surviving hosts must have enough resources to power up and run the vm’s from the failed host. If you do not have enough resources and you Admission Control is set to “Enable: Disallow VM power on operations that violate availability constraints” you will not be able to power on any new vm’s. You will be able to create the new vm’s.
