The app store -- though not officially called an "app store" due to a pending dispute with Apple -- launched in beta this month with 100 applications and 400 professional services from Microsoft partners. The apps and services are available for Exchange, Lync, Office and SharePoint, but SharePoint is the real key for the app store, suggests Gartner analyst Mark Gilbert.
"I've been suggesting to Microsoft that they needed an app store for SharePoint for probably five years now," he says.

Despite the previous lack of an app store, a large number of third-party vendors have built applications to add functionality to SharePoint.
But with Microsoft trying to expand usage of SharePoint Online, Gilbert says tools for customizing SharePoint and industry-specific services will be necessary. For example, HR departments or pharma companies want reliable tools that are geared toward their specific needs and help them get SharePoint deployments up and running, he says. In general, SharePoint requires more customization than other Microsoft software.
"Offering a generic SharePoint experience won't really satisfy most users," Gilbert says.
Microsoft is locking down the Office 365 Marketplace with strict requirements for applications to be listed. Applications will have to pass the "Microsoft Platform Ready" test, which will become available when Office 365 exits beta and enters commercial availability. "All software and services solutions will be subject to Microsoft evaluation to make sure those solutions add value to Office 365 customers," Microsoft says.
This approach, apparently more strict than what you'd see with mobile phone app stores, makes sense given that these applications and services will be targeted at corporate users.
