The voice, video and messaging app became a hit in the 2000s by letting people talk with friends and family members without paying long-distance fees.
Microsoft has promoted Skype in Outlook and Windows and even enriched the app with its Bing generative artificial intelligence chatbot.
In March 2020, Microsoft said Skype had 40 million daily active users, a number that's since slipped to 36 million, according to a spokesperson.
"Skype will remain a great option for people who love it and want to connect via messaging, audio and video calling, and Bing Chat," a Microsoft spokesperson wrote in an email.
