• Never understood the concept of having to have at least two windows - the original Skype UI is much better with regards to this. This is a productivity killer. At least allow to right-click in the conversation list pane (to the left) within the chat window, and open a new IM from there (currently it does not have any context menu).
• When you hover over the small user icon on the second row and move the mouse away from the conversation window, the window disappears. Audio remains connected. The conversation window cannot be restored or located either by using Alt+Tab or by hovering over the Skype for Business icon in the taskbar.

Keeping chat conversations and call history on your Windows PC or Mac isn’t a good idea, and that’s for many reasons. Most importantly because it poses a risk of data breach. Skype chats and call history may contain sensitive and confidential information. Anyone with access to your PC that you had used for Skype conversations can get unauthorized access to all your sensitive chat and call history.

However, you can overcome this potential data privacy risk by deleting the Skype conversation and call history, which is quite easy!

In this guide, you will learn how to delete Skype conversations and call history on Windows 10 and Mac systems. You will also learn about secure eraser method and why it is crucial to erase Skype history rather than just clearing or deleting it from your Windows 10 PC or a Mac system.

Steps to Delete Skype Conversation and Call History

These steps will help you clear Skype chat history. However, remember — deletion wouldn’t remove other sensitive data stored by Skype and other chat messenger app, including web browsers. Moreover, cleared and deleted history also remains recoverable. So, if you wish to permanently remove (i.e. erase) your Skype chats and call history, including other sensitive data stored by the app beyond recovery, skip to the secure erase method steps discussed in this post.

On your Windows 10 PC,

• Open Skype and sign in to your user account
• Go to Tools>Options
• Click on the Privacy Settings tab with a padlock icon in the left-pane
• Click ‘Clear History’ listed under the header ‘Keep history for.’

NOTE: Next time you start Skype, the app may sync and download about 30 days of recent chat and call history from Skype Cloud servers on your PC.

However, the problem can be resolved by scheduling automatic eraser task. For that, you would need to use a file eraser tool, as discussed below in the secure erase method in this post.
