When we were testing Exchange, we created and ORG (theORG) and created a site (tstSite) with ONE server (serverONE)
On this server we created mailboxes. When tests were accepted, all mailboxes were migrated to an official Site (offSite) on different servers.
Some public folders are still on tstSite/serverONE but are replicated to offSite/someServers
Events Library are still on tstSite/serverONE
I want to remove from theORG, tstSite which is now useless.
What are the steps to follow to avoid loss of information.
