Participate in Microsoft's Customer Experience Improvement Program (CEIP)

If your organization has turned on this feature, you can decide to take part in the Microsoft Customer Experience Improvement Program (CEIP). When you participate, your Windows Phone will automatically send basic, anonymous information to Microsoft about how you use your programs and devices, the types and number of errors you encounter, and the speed of services. This information is combined with other CEIP data to help Microsoft solve problems and improve the products and features that customers use most often. Microsoft does not collect your name, address, or other contact information.

Your participation in the CEIP is off by default, as you'll see the first time you sign in to Lync 2013. You can choose to take part in CEIP at that time by moving Customer Experience Improvement Program to On. Or, if you decide later that you want to take part, tap the More button … > Settings > Help us improve Lync and move Customer Experience Improvement Program to On.
