I am not sure how we missed this little tidbit but RIM let us know that BlackBerry Enterprise Server 5.0 service pack 1 with Maintenance Release 1 adds support for Microsoft Exchange Server 2010. They have also made BES 5.0 available in 6 languages including English, French, German, Italian, Japanese and Spanish.
Added in this announcement is compatibility with IBM Lotus Domino 8.5.1, VMware ESX 2.52 to vSphere 4.0, Microsoft SQL Server 2008 and SQL Server 2008 Express, DBNS for Windows Server 2008, and NTLM v2 authentication protocol.

Hopefully RIM will soon be adding support for Microsoft Outlook 2010 in BlackBerry Desktop Manager soon…
