Scoping the problem

Let's assume that you want to troubleshoot issues that occur when users try to join a Skype for Business Online (formerly Lync Online) meeting by using Lync 2010, Lync 2013, the Lync for Windows Store app, or Lync for Mac 2011. Before you start, ask yourself and any external users who are experiencing the issue the following questions:

• How many users does the problem affect?
• Are the users internal or external to your organization?
• Can the affected users reproduce the problem on a single computer or on multiple computers?

When you have the answers to these questions, see the following table to determine the kind of issue that you're dealing with. This table is provided to help scope the problem to a certain category. However, some categories may be outside the technical support boundaries of a Skype for Business Online support engineer.

Read the table as in the following example:

Multiple users... (but not a single user) ...from outside our organization...Can't join a Skype for Business Online meeting from multiple computers: (is usually caused by) Lync federation issue or external network issue.

Be aware that each column and each row are mutually exclusive. That is, the issue affects either a single user or multiple users, and the issue can be reproduced either on one computer or on multiple computers.

Problem

Note

If you don't experience one of the symptoms that are listed in the following table, use the scoping table in the 'Scope' section to narrow the problem to a specific kind of issue. Then, you can troubleshoot the issue by following the steps that are outlined here.

Troubleshooting Windows client issues

To resolve any client or computer issue, first make sure that the computer is up to date. The computer should have the latest operating system updates, audio and video drivers, and software application updates to make connecting to a Skype for Business Online meeting a successful experience. To do this, follow these steps:

1. Run Windows Update, and then verify that all optional hardware updates are installed. Specifically, make sure that video, audio, and network drivers are up to date.

2. Verify that Lync is up to date. See Lync Downloads and Updates for the latest Lync updates.

   Select your version (2013 or 2010), and then select Lync client under Category.

Now that the computer is up to date and meets all minimum system requirements, clear any cached credentials or certificates from previous logons:

1. Verify that the user has the correct certificates in Certificate Manager. To do this, follow these steps:

   1. Open Windows Certificate Manager. To do this, click Start, click Run, type certmgr.msc, and then click OK.
   2. Expand Personal, and then expand Certificates.
   3. Sort by the IssuedBy column, and then look for a certificate that is issued by Communications Server.
   4. Verify that the certificate is present and that it isn't expired.
   5. Delete the certificate, and then try to sign in to Skype for Business Online. If you can't sign in to Skype for Business Online, go to step 2.

2. Remove the user's Skype for Business Online credentials from the Windows Credential Manager. To do this, follow these steps:

   1. Click Start, click Control Panel, and then click Credential Manager.
   2. Locate the set of credentials that are used to connect to Skype for Business Online.
   3. Expand the set of credentials, and then click Remove from Vault.
   4. Try to sign in to Skype for Business Online, and then type the new set of credentials.

Skype for Business Online falls back to 'anonymous join' if it can't authenticate. As long as anonymous participants aren't explicitly blocked from joining the meeting, they should always be able to join the meeting.

Troubleshooting network issues

1. Verify that the computer is connected to the network. Determine whether the computer can access other websites.
2. Verify that the network meets the requirements for connecting to Skype for Business Online. For more information, see You can't connect to Skype for Business Online, or certain features don't work, because an on-premises firewall blocks the connection .

Fixing OCSMEET file associations in Windows

1. Verify that Skype for Business Online is the default program that is used to open .ocsmeet files. To do this, follow these steps:

   1. Click Start, click Control Panel, and then click Default Programs.
   2. Click Associate a file type or protocol with a program.
   3. Scroll down to .ocsmeet, and then verify that **Microsoft Lync **is selected as the Current Default option.

2. If step 1 doesn't resolve the issue, perform an Repair an Office application, or reinstall Lync 2010.

Troubleshooting Identity issues

This specific issue occurs when two users of the same Office 365 organization share the same user name (alias). Because of how Lync generates meeting URLs, two users on the same Office 365 organization who have the same user name will share the same meeting URLs. This causes the Skype for Business Online conference to become corrupted.

To resolve this issue, change the user name of one of the users who has the duplicate user name.

Troubleshooting Lync federation issues

If external users (and only external users) can't join a Skype for Business Online meeting, first determine whether they're trying to join as authenticated users or as anonymous users.

• If the user is trying to join as an authenticated user from another Lync or OCS organization:
  • Your Skype for Business Online organization must have External Communications enabled, and external communication must be completely open. Or, the external user’s domain must be in the Allow list.
  • The external organization must have federation configured correctly from their side, too.
  • For more information about federating with a Skype for Business Online organization, go to the following Microsoft TechNet website: Configuring Federation support for a Skype for Business Online customer
  • If authenticated join doesn't work, Lync should automatically try to join as an anonymous or guest user.
• If the user is trying to join as an anonymous user from Lync Attendee, or if the Lync Web App or is dialing in to a Skype for Business Online conference with an ACP access number:
  • For anonymous join to work, a specific DNS SRV record must be present in DNS.
  • For various methods of confirming your Skype for Business Online DNS records, see Troubleshooting Skype for Business Online DNS configuration issues in Office 365.

Joining meetings by using the Lync Web App

If these troubleshooting steps don't resolve the issue, and if joining the meeting immediately is a bigger concern, use the Lync Web App. Be aware that the Lync Web App doesn't include Voice over IP (VoIP) functionality. That means that participants can only view sharing sessions. To do this, follow these steps:

1. Copy the Join URL from the meeting invite, and then paste it into Internet Explorer. (Warning: Don't press Enter yet.)

2. Add '?sl=1' to the end of the URL, and then press Enter.

   Note

   You must have Silverlight installed to use the advanced features of the Lync Web App.

Troubleshooting issues with third-party software

If you’re using third-party software, you may be asked to update, disable, or remove the software as a troubleshooting step. If the issue is resolved after you take one of these actions, you may be referred to the third-party manufacturer for more help or to perform additional troubleshooting.

Problem

A Skype for Business Online (formerly Lync Online) user tries to sign in to the Lync 2010 mobile client from a Windows Phone, Apple iPhone or iPad, Google Android, or Nokia Symbian device by using the Auto-Detect Serveroption to determine the Skype for Business Online server. However, the user receives the following error message:

Solution

To troubleshoot this issue, follow these steps.

Step 1: Verify the Lyncdiscover CNAME record

To verify that the Lyncdiscover CNAME record is present in the Domain Name System (DNS) records, go to the Lync Connectivity Analyzer, and select Office 365 Custom/Vanity Domain Name Settings Test for Lync. Enter the sign-in address that you're using when you to try to sign in to Skype for Business Online (for example, darrin@contoso.com), and start the test.

If any issues are detected, check the DNS configuration with your domain registrar.

Step 2: Try a Wi-Fi connection

After you verify that the Lyncdiscover CNAME record exists in DNS, check whether a Wi-Fi connection is available. If a Wi-Fi connection is available, try to connect to Skype for Business Online. This test determines whether the DNS lookup failure is occurring on the mobile carrier, the Wi-Fi connection, or both.

Step 3: Query DNS from the mobile carrier

The next step to check whether the mobile device can resolve the Lyncdiscover CNAME record in DNS is to query DNS from the phone itself. This is difficult to do because most mobile devices don't include integrated network diagnostic tools. So, users have to download an application that performs these kinds of functions. Demonstrating the use of these applications is outside the scope of this article and outside the scope of Office 365 technical support. You may need to contact your carrier for additional assistance if the connection is only failing when connected to your data carrier.

More Information

This issue occurs if the Lync Mobile Autodiscover process fails and the user's Skype for Business Online server can't be determined. This issue may occur if one of the following conditions is true:

• The Lyncdiscover CNAME record isn't set up.
• The Lyncdiscover CNAME record is set up incorrectly.
• The Wi-Fi connection is blocking DNS queries.

For the Lync Mobile Auto-Detect Serveroption, specific CNAME records must be present in DNS for the Lync 2010 mobile client to determine the home server of the Skype for Business Online user. The Lync 2010 mobile client tries to discover the user's home server by querying the following CNAME records in DNS:

• LyncdiscoverInternal.<domain>
• Lyncdiscover.<domain>

Additionally, the CNAME records in DNS must meet the following criteria. Otherwise, the Lync Mobile sign-in process will fail if the Auto-Detect Server option is used.
