Research In Motion announced BlackBerry Business Cloud Services for Microsoft Office 365:

“… a new RIM-hosted online service for midsized businesses and enterprises that extends Microsoft Exchange Online to BlackBerry® smartphones, and allows organizations to self-manage their BlackBerry deployments in the cloud. An open beta for the service is launching today in over 30 countries.“

My Comments
1. The service works with Exchange Online in Office 365 – for email, calendar, and other PIM data.

2. Office 365 includes other capabilities too – SharePoint Online, Lync Online, Office Professional Plus, and Office Web Apps – but there is no mention of support for these. Hopefully the lack of support for these other services is reflective of a staged approach, with Exchange Online support the beachhead.
