Naming your app
The name of your app shouldn’t include the words SkyDrive, Hotmail, or Messenger or be similar to these terms in either sound or spelling. (For example, don’t prefix your app name with “Sky”, or “Hot”). This restriction applies to both the naming of apps and their naming in any online store.
The only exception is if your application works exclusively with SkyDrive, Hotmail or Messenger. In this case, your application can post-fix “for SkyDrive” or “for Hotmail” in your app name. For example, “Contoso Photo Fixer for SkyDrive”.
Any additional use of Microsoft trademarks would require permission or a license from Microsoft.
Your app’s logo
The SkyDrive, Hotmail or Messenger icons cannot be combined with other elements, graphics or logos—visual separation from any other graphical or textual elements is required. For instance, do not combine the Hotmail icon with another company’s logo in one button or application icon.
Using the Live Connect names and logos
When you refer to SkyDrive, be sure to use the proper form - a capital S and capital D. For Hotmail, use a capital H and lowercase m. You can use the SkyDrive, Hotmail and Messenger logos in the user interface to identify the network of origin for data in your application and on buttons to initiate the process of connecting your user to Windows Live services.
Also, never modify our logos and always be sure to use each to refer only to the service that it corresponds to.
You may use the icons in this zip file in the user interface of your application to connect your application users to our services, provided that your use complies with these guidelines. By using these icons, you agree to be bound by these guidelines:
Microsoft makes no warranties regarding the icons, and hereby disclaims all warranties that might otherwise be implied by law, including warranties against infringement.
