• It's a very international product. It has been available for very long time, which makes it very wide spread - it has a good user base.

• Skype's UI leaves a lot to be desired, especially considering newer platforms like Zoom, Teams, Slack, Meet, and so on. It's slow and lacks many features that are now de facto in the newer communication apps.
• Skype calendar also is often buggy - meeting times do not get updated on the calendar even if the correct time does come up on the Outlook calendar.
• It does not give you the option to mute chats - oftentimes, you want to keep some group chats on mute without leaving them entirely.
• Closing off a chat before it's saved will remove it from Skype history. You'd need to go search for it on Outlook mail.

• Being able to schedule Skype for Business meetings through Outlook has meant meetings with colleagues without a meeting room has been a great enabler.
