Microsoft Office was designed from the ground up as a powerful productivity platform for numerous PC-related tasks and jobs, and has gained massive popularity over the years, becoming the leading solution on the market.
However, making it a truly all-purpose tool, able to perform in practically every scenario that the modern workplace produces, is no small task.
To counter this limitation, Microsoft has included the possibility for independent developers to create their own functions into the platform, without compromising its integrity or copyright licenses, by introducing the MAPI (Messaging Application Programming Interface) protocol – a sort of “bridge” for anyone to use between the closed architecture of Office and supplemental software written in popular programming languages in order to include a desired feature. This protocol has allowed many to produce their own long-sought productivity improvements that Microsoft had or has no desire to implement owing to small margins – the main features of Office require many man-hours to maintain as it is. Consequently, an impressive number of such software products have appeared on the Internet over the years as the result.
Since the 2013 version, Microsoft Outlook users have had the option to activate automatic reminders concerning message where attachments may have been forgotten.
For many years Microsoft Outlook was the most popular email client in the world. According the latest research, Microsoft Exchange Server accounts for more than half of business mailboxes in 2014; that is, 500m in absolute figures. Many of these users are using Microsoft Outlook, where Outlook Web Access still plays a companion role.
The installation base of Microsoft Office is about 1 billion. This figure can be found in many articles. On July 7, 2014 Microsoft reported that over 1.1 billion people use Microsoft Office. So the estimated base of Microsoft Outlook users in 2014 is between 500m and 600m.
Some interesting numbers can be found in the research of the Radicati Group. This company specializes in researching e-mail, security, instant messaging and social networking with a focus on enterprise market.
In the study entitled “Microsoft Exchange Server and Outlook Market Analysis, 2010-2014”, we see that on-premises Exchange in 2010 has 76% of mailboxes as opposed to 15% being hosted and 9% from managed Exchange.
