Comcast has arranged to give its business-class customers free access to Microsoft Communication Services. Comcast said these services include corporate-class e-mail, calendaring and document sharing.

The applications are all based on Microsoft Exchange Server 2007, Microsoft Office Outlook 2007 and Microsoft Windows SharePoint Services 3.0. All applications are Internet-based, and as such will be accessible from any computer.

That also means that business customers will not have to support and maintain those services on their own.

Microsoft Communications Services from Comcast – the official title of the service – will be backed by 24×7 Business Class customer support from Comcast, which will serve as an SMB’s “help desk.”

Bill Stemper, president of Comcast Business Services, said, “Many of our small-business customers use stand-alone Microsoft products on their own PCs, which benefits individual employees. Now, as part of their Comcast high-speed Internet service, they can quickly schedule meetings, share a common address book, or easily share or review important documents, which benefits the entire business.”
