Sproqit Technologies will announce a workgroup version of its Sproqit email tool that gives users remote access to their Outlook inboxes from smartphones and wireless handhelds. Sproqit Workgroup Edition will be available from the end of July and will support up to 50 users. Sproqit currently supports only Microsoft Exchange Server, but the firm plans to add support for Lotus Domino mail systems when it ships Sproqit Enterprise Edition later this year.
