HyperOffice is a slick online collaboration service that lets you store and access files, tasks, contacts, links, an documents—almost any digital file—on a HyperOffice-hosted website. A fully hosted alternative to building your own Microsoft Exchange and SharePoint servers, HyperOffice is feature-rich, but it has a few minor interface glitches that need to be worked out. For $44.99 per month for five users, HyperOffice is easy to set up as both an intranet and an extranet that lets co-workers, customers, and clients see specific data. If your company is thinking about cloud-based collaboration, you’ll be impressed with this inexpensive product.
