Unable to Join
Lync Server 2010
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.
