Interesting little snippet posted on the RIM web site today.
"October 20, 2009 - Research In Motion (RIM) is pleased to notify you that we are working in close collaboration with Microsoft on compatibility and support for BlackBerry® Enterprise Server for Microsoft® Exchange Server 2010. Compatibility is expected later this year. BlackBerry® Technical Support Services for BlackBerry Enterprise Server for Microsoft Exchange Server 2010 is expected within 30 days following the global availability of Microsoft Exchange Server 2010."
No doubt that will mean BES only, as the Blackberry Professional version seems to be ignored. Looks like I will be giving up my Blackberry when I move across to Exchange 2010 shortly.
