Overview

Use Microsoft Skype for Business to access Indiana University's UniCom service.

For devices supported by UITS, you can change which device Lync uses for audio from within Lync for Mac. If this doesn't work for your device, you may need to try troubleshooting your macOS System Preferences.

Change or configure audio devices in Lync for Mac

If your preferred device was not automatically set as the default audio device when you connected it, you can change it by clicking the microphone icon in the lower left of the main Lync for Mac window, and selecting your device from the pull-down menu.

To change the audio device while in a call, click the microphone icon in the lower part of the conversation window, and select your device from the pull-down menu. Microsoft office for mac home and student 2011 free trial software.

Camera troubleshooting

If you are having problems with your built-in or attached USB camera for video chat, quit all applications that use video, and then launch Lync for Mac only.

The built-in camera or other attached camera may be controlled by the first video application launched. For example, if video applications like FaceTime or Skype are launched before Lync, those applications can be in control of the camera and prevent its use in Lync.

Audio troubleshooting in System Preferences

If you are having audio problems, and you can't resolve them within the Lync for Mac client, you can specify the input and output devices in your system sound settings:

Lync

1. Open System Preferences and select Sound.
2. Select the appropriate settings for 'Output' and 'Input'.

Each output and input device can have its own level settings. For example, a USB headset will have an independent volume setting from the internal speakers, or from headphones or external speakers plugged into the 1/8' audio out port. The built-in microphone on a Mac will also have a different input volume from a USB headset microphone. Setting the input between half and full seems to be appropriate.

Configure preferences and start over

If other troubleshooting does not solve the problem, it may be necessary to clear all preferences for Lync for Mac and then set it up as if it were a new installation. It is usually unnecessary to reinstall the application. To clear out all preferences and other files associated with Lync:

Microsoft Lync Download

1. Quit Lync for Mac.
2. In your Home folder, open the Library folder. Note that macOS hides your Library folder. To access it:
   1. Press Command-Shift-g, or from the Go menu, select Go to Folder...
   2. In the Go to Folder drop-down window, enter ~/Library, and click Go.
3. Remove the following files from your Library folder:

   • /Users/username/Library/Preferences/ByHost/MicrosoftLyncRegistrationDB.xxxx.plist

   • /Users/username/Library/Logs/Microsoft-Lync.log
4. In your Documents folder, remove the following:
   • /Users/username/Documents/Microsoft User Data/Microsoft Lync Data
5. Optionally, also remove Microsoft Lync History. This will delete saved conversations. For Mac users, the conversation history is not saved to the Exchange account, but instead is saved locally to the Mac. To delete the history, remove:
   • /Users/username/Documents/Microsoft User Data/Microsoft Lync History
6. Open Keychain Access from the /Applications/Utilities folder:
   1. Delete any keychains on the left that look like the following, where emailaddress is your email address:
