I guess many people have been waiting on official statements around this. Although this was posted a couple of days ago I wanted to make sure everyone has seen it as it could be crucial for your Design / Environment.
As of today, the following support scenarios are being updated, for Exchange 2010 SP1, and later:
- The Unified Messaging server role is supported in a virtualized environment.
- Combining Exchange 2010 high availability solutions (database availability groups (DAGs)) with hypervisor-based clustering, high availability, or migration solutions that will move or automatically failover mailbox servers that are members of a DAG between clustered root servers, is now supported.
In other words, enabling VMware HA and VMware DRS is perfectly supported for your Exchange 2010 SP1 environment allowing for greater flexibility! Make sure you reconsider some of the design / implementation decisions you made in the past when these constraints still applied. Also, if you are re-evaluating your mail solution… check out Zimbra. I’ve been using it for over 6 months and couldn’t be happier. I used to be a huge Exchange/Outlook fan and expected that I would not be able to adjust to another platform, but Zimbra is in my opinion on par with Exchange and those little extras like the zimlets just make your life easier. (Integrating with applications, websites, social networks… you name it)
