Upon bootup, the cluster service didn't want to start anymore. So our administrator went into the cluster's services, changed the logon from local system to our cluster service user, and rebooted the Exchange server again. This brought the cluster up and got email going, but now we can't mail-enable new Exchange public folders. We get the message: "The mail proxy for this folder cannot be found. This may be due to replication delays. The mail-enabled pages will not be shown."
During off hours, I went in and changed the cluster service back to the local system logon and rebooted. Amazingly, the cluster service started and email came up, but I still have the same problem with Exchange public folders.
Also, we are going to be migrating to Exchange Server 2003 and have recently put in a two-server active-passive cluster on the network. I don't know if this is related or not, but I thought I'd mention it.
