One of my IT colleagues came to me asking why the quota on his mail file was not the same on different servers in our mail server cluster. I said that I didn't know, but that I would investigate it and get back to him. I ran across
Technote #1112781: Which Database Properties Replicate in the Lotus Support Knowledgebase. I guess I will have to come up with some code that will propagate the quota from the user's home servers to all the other servers in the cluster.
