We have 2 exchange servers set up in a cluster. They are both VM's. Server 1 has 12GB, server 2 has 8GB. About 250 users and including groups etc about 500 email addresses.
We constantly receive alerts from our monitoring portal warning that the memory utilisation is critical at 98% etc. I have checked online and a lot of people bleive it is a normal part of how Exchange work - to sit in Ram etc.
Is this RAM utilisation correct? Or are we missing something. We are considering turning of memory monitoring but I dont need to say that that is not ideal.
