2017 - Mobile Outlook gets much smarter search to win over Zimbra


Microsoft unveiled a redesigned version of its popular Outlook mobile app for iOS and Android, which most notably includes a more intelligent search feature, powered by Microsoft Graph, along with other changes to navigation and conversations. Microsoft Graph is being used to turn Outlook’s search feature into a tool that can surface more than just emails – it will be augmented to include things like contacts, attachments, flight and travel itineraries, package deliveries and more. Search is also becoming a more central part of the experience in the new version of Outlook. When you tap into search it won’t be a blank screen, but will include proactive suggestions of your top contacts and recent files, as well as showcase things happening ‘today,’ like your travel plans – all before you even kick off your search. Plus, when you start typing, the auto-complete suggestions will display names from your most frequently contacted recipients first.

2005 - Zimbra readies open-source business e-mail to fight MS Outlook

Zimbra eleased the messaging and calendaring software  targeted specifically to businesses. Using an open-source business model and a modern development technique known as Ajax, the start-up is looking to unseat entrenched messaging suppliers IBM and Microsoft. The company, which launched its first beta in August, makes its Web-based messaging product available for free with an open-source license. It intends to make money by charging corporate customers a license fee for a more functional "Network" version and a yearly support fee based on the number of mailboxes used. The edition includes features to ease administration, such as simplified backup tools, support for clustered servers and storage tools for managing end-user mailbox accounts.
