To use the service, head over to Skype.com and click "Start a conversation". Once you add your name, you'll be given a link to your conversation that you can share with friends or anyone that you want to join.

Microsoft promises that you'll be able to use all of the free features of Skype, which include "one to one and group instant messaging, voice and video calls, screen sharing and even file sharing". Group instant messaging can include up to 300 people, and a group video call can include up to 25.

If you're signed in as a guest, your conversation will only last for 24 hours. Once that time is up, you'll be expected to sign up for a free Skype account if you want to return to the conversation.

If you're already on Microsoft's communication platform, you might want to check out the new Skype Insider Program, which provides early access to the app on iOS, macOS, Android, and Windows.
