When Exchange 2010 became generally available last November, the first release had several issues that prevented interoperability with Cisco Unity Unified Messaging. Cisco and Microsoft together have identified these issues and Microsoft has delivered an updated version of the Messaging Application Programming Interface (MAPI) addressing the primary interoperability issues. Cisco is now working aggressively to validate the new MAPI version as well as make the necessary changes in Cisco Unity to support Exchange 2010 along the following timeline:
Cisco Unity 7.0 – March 31, 2010
Cisco Unity 5.0 – May 31, 2010
Cisco Unity 8.0 – June 30, 2010
An Engineering Special (ES) build will be available for download as validation is completed for each release of Cisco Unity.
We urge Cisco Unity Unified Messaging customers who are using versions older than Unity 5.0 and who plan to upgrade to Exchange 2010 to first upgrade to Cisco Unity 7.0 (once the ES is available in March) before an upgrade to Exchange 2010.
Please let us know how we can help you with a smooth migration to the latest version of Cisco Unity and your interoperability with Exchange 2010.

ES 86 is now avaialable on the downloads page. Apparently 85 had an issue with corrupting Exchange search folders according to the release notes.
Cisco Unity 8.0 interoperability with Microsoft Exchange 2010
I’m happy to announce that the engineering special required to support Unity 8.0 with Exchange 2010 is now posted externally on Cisco.com, version 8.0(3) ES2.
