Skype stores files and photos you've shared, calls you've recorded, and other items for easy access across all of your devices.
However, each item has a different length of time that it's available in your chat history:
|Item Type ||Duration Available |

|Videos ||Determined by user* |
Note: Videos larger than 100MB will be saved as a File so it will be available for 30 days.
|Pictures ||Determined by user* |
|Files ||Available for 30 days |
|Voice messages and Voicemail ||Available for 30 days |
|Call recordings ||Available for 30 days |

*Messages, videos and pictures are available until they are deleted or dated back to April 2017.
