2015 - Microsoft released Office 2016

Microsoft is releasing Office 2016, offering refreshed versions of Word, Excel, PowerPoint and other applications. The look and feel of the programs will be familiar to anyone who has used the 2013 edition of Microsoft’s productivity software. Much of what’s new with the 2016 edition is better integrated collaboration tools. A new co-authoring feature allows multiple users to edit the same document in real time, long a feature of Office’s Web-based cousins and apps built by Google and other Microsoft competitors. Also arriving is chat service Skype, which will be embedded within Office apps to let users send instant messages, share images of their work, or video chat from within a document. Other new features include a search tool to locate specific functions within Office, and a research tool that pulls data from the Internet into documents. Microsoft is pushing to sell the software suite through Office 365, the company’s subscription program, instead of the traditional model of a one-time purchase that gives the user rights to the software in perpetuity.

2013 - New Office 2013: Bring Your Own Office? - a new advantage over Microsoft Exchange

One of our Enterprise 2.0 2013 predictions was the further development of BYO (Bring Your Own) trend. We said that with the own devices, employees will bring to work their own apps. Today, after the official release of Microsoft Office 2013, it looks like our prediction is coming true. Just look at the video: some guy is showing how he works everywhere with his own office. It's definitely his OWN office (Home Premium), because the enterprise version of Office 2013 will appear only in a month. But what is the reason of this phenomenon?

The reason is in the new MS Office licensing scheme. Microsoft doesn't want to sell Office any more, it wants users to subscribe to it. No, the one-time payment option is still available, but it looks far less attractive than subscription.

Let's compare. The annual subscription to Office 365 Home Premium costs $99. It includes Word, Excel, PowerPoint, OneNote, Outlook, Publisher and Access. The price of the similar suite of Office Professional 2013 is $400. And, in case with subscription - you additionally get 20 GB of SkyDrive space, 60 minutes per month for Skype IP-telephony and you can install Office on up to 5 computers / tablets. But when you buy the Office - you can install it on one computer only, and no other bonuses.

So most users will probably choose the subscription option and will be able to install the own Office on the work computer (and small businesses will be able to save money on this).

The functional advantages and disadvantages of the new office we have already reviewed earlier. About the differences of the enterprise version we'll talk in a month, when it appears.

2010 - Microsoft Office 365 = Microsoft Exchange + Office Web Apps

Today, Microsoft has rolled out a new service Office 365, which is a reincarnation of the SaaS package BPOS. The name change was expected, since Microsoft critics have referred BPOS as "Big Piece of Shit" instead of "Business Productivity Online Services". But not only name is to be changed. The new service except SaaS versions Exchange Online, Sharepoint Online and Lync Online, will include the online office tools Office Web Apps. I.e. Office 365 can now be considered as a full-fledged alternative to Google Apps. The service will be available in 2 editions. Small Business Edition for companies with less than 25 users costs $6/user/month and includes the basic functions. Enterprise edition provides additional customization and administration features, full functionality and provides users with desktop suite Office Office Professional Plus with pay-as-you-go licensing. This edition costs from $2 to $ 27/user/month depending on configuration. Recall, Microsoft also plans to include its CRM and ERP to the SaaS suite. At the moment, Office 365 is in beta stage and will be available worldwide next year.
