Is the android app compatible with my Motorola MB911 phone. I have tried to download from play.Google but no luck...

Hi,

To run Microsoft Lync 2010 for Android, the phone must be running Android 2.3 or a later phone-oriented operating system.

You can try to download Lync 2010 from Android Market with the following steps:

1. From your phone, go to the Android Market, and search for Microsoft Lync 2010.
2. Tap the Install button. As soon as the app is installed, it appears on your phone.

More details you can refer to the part of Microsoft Lync 2010 for Android in the link below:
