Currently, the domino server is configured as clustered and replicated. Currently, the cluster is Active-Active. One of my clients reported his email which is connected to Server 2 increased suddenly exceeding his mail quota. I've increased the mail quota after reported but the problem re-occurred again..I've temporarily connect him to Server 1 to use Lotus Notes. I've backup and deleted his mail in Server 2 then created another replica to Server 2, yet after a day it occurred again.
I would like to ask if you can have another suggestion. I have also check his mail rules and settings.
I do notice when opening his mail file in Lotus Domino, they are different template look but have the same mail version.
