Skype for Business Mac Chat History Storage Location I downloaded Skype for Business on Mac and I have tons of Chats saved, but there is no setting for deleting them after X amount of days or a way to delete them in mass. Currently, I have have to right click then delete on every single chat.

Does anyone know where the Chat history is stored on Mac?
Open Finder and navigate to ~/Library/Application Support/Skype/.
The “~” sign means your home folder. To find your home folder, open Finder and in the main menu, select Go > Home or press Command (Apple) + Shift + H keys.
It is the folder that has your Skype Name. 

An app restart may be required after making modifications.

Also, try this location: /Library/Application Support/, as there is a difference when the tilde sign is used.

Furthermore, the stores file can be found in ~/Library/Containers/com.microsoft.SkypeForBusiness, which is the user folder according to This Post
