Important news about Email Servers for business
2024. Microsoft slowly discontinues local Exchange
In a move that could only be described as the sort of thing you'd expect from a giant, universe-straddling tech company, Microsoft has politely informed the world that support for Exchange Server 2016 is coming to a dramatic close. On October 14, 2025, to be exact, it will vanish into the ether, much like your last attempt at finding a file you swore you saved. The company encourages everyone to scuttle over to the cloud, where presumably everything will be just a tad less confusing. For those brave souls determined to cling to the notion of running their own email servers, there’s nothing to look forward to except Exchange Server 2019—unless, of course, you’re waiting for the mythical Exchange Server Subscription Edition, which Microsoft, in its infinite wisdom, assures us will appear “sometime in the early part of Q3 of 2025.” If you're lucky enough to be on Exchange Server 2019, upgrading should be as painless as upgrading ever is. But if you're still hanging onto 2016, get ready for a journey akin to building a spaceship out of old cereal boxes, where entire new infrastructures must be forged and your mailboxes shuffled to their new cosmic homes.
2019. Email collaboration software Zimbra added own document editors
Zimbra Network Edition now features integrated feature-rich office productivity suite - Zimbra Docs. It's free and you don't need MS Office license. You can now create and edit documents, spreadsheets and presentations right in Zimbra. Zimbra Docs supports the most popular document formats (xls, doc and ppt and more). The apps are called: Zimbra Writer (document editor), Zimbra Calc (spreadsheets), Zimbra Impress (presentations) and Zimbra Briefcase (for converting and sharing files). The heart of the service is Zimbra Docs server that must be installed on one or more dedicated nodes running RHEL 7 / CentOS 7, Ubuntu 16.04 LTS, or Ubuntu 18.04 LTS. Besides own built-in office, Zimbra features LibreOffice integration, that is also free.
2018. IBM sold Lotus Notes/Domino, Websphere Portal and other software to HCL
In a move that might seem to the average intergalactic hitchhiker as logical as using a towel to fix an interplanetary bypass, IBM has decided to part ways with its venerable, if slightly dusty, collaboration software Lotus Notes, handing it off to the eager hands of HCL for a cool $1.8 billion. Once upon a time, these tools were the gleaming core of IBM’s empire, but last year, like a commuter reluctantly giving up their seat on a packed hyperspace transport, Big Blue ceded development to HCL while clinging to sales and marketing as if they held the last cup of tea in the universe. But now, weighed down by the $34 billion spent on Red Hat (a rather flashy cloud acquisition), IBM appears to have realized it’s far easier to hop aboard the hybrid cloud train than lugging around legacy software that’s about as relevant as a Betelgeusian VCR. Meanwhile, HCL, clearly starry-eyed and wearing an "I
2015. Synacor acquired Zimbra
The open-source email and messaging software provider Zimbra has been purchased by Synacor for $24.5 million. Synacor describes itself as the multiscreen technology and monetization partner for video, internet and communications providers, device manufacturers and businesses.

Zimbra has previously been acquired by Telligent, VMWare and Yahoo. This acquisition follows the news earlier this week that Verint acquired Telligent (Zimbra Social) from Zimbra.
