Unable to Join

Topic Last Modified: 2012-10-18

Issue   You are not able to join a Microsoft Lync 2010 meeting or conference call.

Resolution   Do the following:

• Make sure your phone or device is optimized for Lync 2010. For a list of optimized devices, see “Phones and Devices Qualified for Microsoft Lync” at http://go.microsoft.com/fwlink/p/?LinkId=208938.
  
• Test your audio device(s) from the Lync - Options dialog box, and confirm that they are functioning properly before trying to join again.
  
• Have participants confirm with their support teams that their networks and accounts support Lync meetings and calls.
  
• For an ad-hoc meeting or conference call, first try sending an instant message to one contact, and then add voice to the conversation. Lastly, add a third person. If instant messaging (IM) and voice work, but conferencing fails, contact your Lync administrator to ensure that the network routes and ports to the A/V Conferencing Server are not blocked.
  
• For a scheduled meeting or conference call, try dialing in with a phone or joining by using the “Join online meeting” link in the Microsoft Outlook meeting request, whichever method you have not already tried.
  
• See if others can join meetings or conference calls. If no one can join (or schedule) a meeting or call, the issue is likely related to network connectivity. (For example, there may be an intermittent issue or temporary network outage.)
  
• If you are conferencing with external contacts, contact your Lync administrator to make sure that your account is enabled for Enterprise Voice.
