Overview
Lync caches files locally on a PC or MAC to pull information quickly and efficiently. However, there are times where it is necessary or helpful to delete those files and force Lync to get a new set from the server.
Common reasons you will want to clear your cache include:
- If you can't log in to Lync
- If your Outlook and Lync integration is not functioning properly
- If you have issues with Presence
