Our active mailbox node ran out of space and I needed to move the token over to our passive node. The passive node has plenty of space. I can't increase the space on the active node and we are moving to a hosted solution by the end of the year and do not plan on getting more space. I want to keep my mailbox sever on the passive node and break the cluster. Thus far I have uninstalled Exchange from the acrtive node and evicted it from the cluster. What do I need to do on the passive node now so that it is stand alone mailbox server?
