Hello. I am planning to deploy an active/passive server environment for Exchange 2013. Here's what I plan to achieve:
- EXCHANGE-A - on production site, active (all mail flow goes through here), member of DAG
- EXCHANGE-B - on disaster recovery site, passive (mail flow goes through here ONLY when activated), member of DAG
I have tried disabling all receive connectors on EXCHANGE-B, however that causes OWA to delay sending messages for around 20 seconds (messages stuck in Drafts folder before being sent out). I have also tried disabling Exchange Transport services on EXCHANGE-B but to no avail.
Is it possible to achieve active/passive mail flow server environment? What is the best way to achieve this? I appreciate any leads on this matter.
