Microsoft confirmed that it will be retiring Skype on Windows Phone 7.

A parcel of Skype's official statement regarding this matter reads:

"We want everyone to experience the best Skype has to offer – from enhanced quality to better reliability to improved security – and the newest version of Skype is the way to do that. So everyone can benefit from the latest improvements, we sometimes retire older versions of Skype across all platforms, including mobile devices. For that reason, we are permanently retiring all Skype apps for Windows Phone 7."

The cessation of Skype on Windows Phone 7 will happen soon, and users will no longer be able to sign-in and access the freemium messaging app.

Users are advised to update to Windows Phone 8 or Windows Phone 8.1 to be able to use Skype, and cancel existing subscriptions to avoid being billed.

Shocked users took it to the official Skype forum to air disappointment over the discovery that the app no longer works on their Windows Phone 7 devices.

The frustration was multiplied for those who are unable to upgrade to Windows Phone 8 or Windows Phone 8.1, because their devices do not support Microsoft's latest OS releases.

To make things worse, it was revealed that Microsoft is still supporting Skype on older version of iOS and Android.

In fact, Skype reversed its original decision to drop Mac OS X 10.5 Leopard support to hopefully pacify outrage from several users that expressed disgust in this forum.

To appease the rage of Apple's Mac community, the messaging app confirmed that a version for Mac OS X will be available soon for download.

Apple has stopped supporting Mac OS X 10.5 Leopard in 2011.

Microsoft acquired Skype back in 2011 for $8.5 billion in cash, and later on terminated its homegrown Windows Live Messenger.

As of April 2013, active Skype users worldwide spent a combined 2 billion minutes in Skype everyday.
