One question I get from a lot of my clients is when will Cisco Unity work with Exchange 2010?  To be honest this is actually holding up a lot of my clients from moving to Exchange 2010.  First of all they need to be certain that their Phone System will work with Exchange 2010 and second they want to make sure it works with Exchange 2010.  Yes, I know, I repeated myself there but honestly clients want to know when it will first be supported.  The second part is they want the technology to be tested and proven, which typically means they want to wait a few months before they make the switch.

Well, I came across a post from about two weeks ago (I know, I’m slow, just been very busy) that had some estimates on when Cisco Unity will support Exchange 2010. 

Here is an excerpt from Matt Wade’s blog:

Cisco is now working aggressively to validate the new MAPI version as well as make the necessary changes in Unity to support Exchange 2010 as follows:

Unity 7.X – March 31, 2010

Unity 5.X – May 31, 2010

Unity 8.X – June 30, 2010

We urge Unity 4.X Unified Messaging customers who plan to upgrade to Exchange 2010 to first upgrade to Unity 7.X once the ES is available in preparation for their upgrade to Exchange 2010.

So, it looks like we are still about two months out.
