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.
| A single user from inside our organization | A single user from outside our organization | Multiple single user from inside our organization | Multiple users from outside our organization | Multiple users from both inside and outside our organization | |

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:
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.
Verify that Lync is up to date. See Lync Downloads and Updates for the latest Lync updates.
Microsoft equivwlent of mac os keychain. 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:
Verify that the user has the correct certificates in Certificate Manager. To do this, follow these steps:
- Open Windows Certificate Manager. To do this, click Start, click Run, type certmgr.msc, and then click OK.
- Expand Personal, and then expand Certificates.
- Sort by the IssuedBy column, and then look for a certificate that is issued by Communications Server.
- Verify that the certificate is present and that it isn't expired.
- 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.
Remove the user's Skype for Business Online credentials from the Windows Credential Manager. To do this, follow these steps:
- Click Start, click Control Panel, and then click Credential Manager.
- Locate the set of credentials that are used to connect to Skype for Business Online.
- Expand the set of credentials, and then click Remove from Vault.
- 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
- Verify that the computer is connected to the network. Determine whether the computer can access other websites.
- 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
Verify that Skype for Business Online is the default program that is used to open .ocsmeet files. To do this, follow these steps:
- Click Start, click Control Panel, and then click Default Programs.
- Click Associate a file type or protocol with a program.
- Scroll down to .ocsmeet, and then verify that **Microsoft Lync **is selected as the Current Default option.
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:
Copy the Join URL from the meeting invite, and then paste it into Internet Explorer. (Warning: Don't press Enter yet.)
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.

-->With Skype for Business, your users can search for and IM with everyone who uses Skype, the free app! This article explains what you need to do so they can add Skype contacts.
You must have admin permissions in Office 365 to do this.
Using the Skype for Business admin center
I Cannot Call A Microsoft Skype From A Mac Download
Sign in with your Office 365 admin account at https://portal.office.com/adminportal/home.
In the admin center, go to Admin Centers > Skype for Business.
In the Skype for Business admin center, choose Organization > External communications.
By default, your users can communicate with all other people in the world who use Skype for Business (assuming your firewall has been configured to allow this).
If you want your users to chat with Skype users, BUT you don't want them to chat with others who use Skype for Business, choose On only for allowed domains. When you enable contact with Skype users, skype.com is automatically added as an allowed domain behind the scenes.
If you want to allow contact from all other businesses in the world using Skype for Business, except specific ones, choose On except for blocked domains, and choose + to add those domains. Everyone will be able to contact you except people on those specific domains. (Some businesses might choose this option, for example, if they are in litigation and need to ensure there's no contact with the other business.)
Choose Let people use Skype for Business to communicate with Skype users outside your organization.
If you're using Windows Firewall, Skype for Business opens the required ports automatically.
If your organization uses another solution to restrict computers on your network from connecting to the Internet, ensure client computers are able to access all of the IP addresses and URLs for Skype connectivity and Skype Directory Search. This may require adding them to the outbound allow list in your firewall or proxy infrastructure configuration.
WAIT UP TO 24 HOURS TO TEST. Any time you change the external communications settings, it can take up to 24 hours for the changes to populate across all the data centers.
Show your users how to find and add Skype contacts to their list of Skype for Business contacts. Point them to Search for people in Skype for Business.
Test and troubleshoot
To test your setup, you need a contact on Skype who's not behind your company firewall. They can be signed in to Skype using a Gmail account, Outlook.com account, or other type of email account.
After you change your external communications settings, WAIT UP TO 24 HOURS TO TEST.
Sign out of Skype for Business and then sign in again so you see the option to search the Skype Directory.
In Skype for Business, search for your contact in Skype, and send a request to chat.
If you get the message it couldn't be sent due to company policy, you need to double-check your firewall settings.
Another way to test whether the problem is your firewall is to go to a wifi location not behind your firewall such as a coffee shop, and use Skype for Business to send a request to your Skype contact to chat.
If you sent your Skype contact a request and they never received it, ask them to send you a request to chat. If the problem was establishing a connection between Skype and Skype for Business, that often solves it.
Now if the message goes through at the coffee shop but not when you're at work, then you know the problem is your firewall.
What you can and can't do
Skype for Business on Mac doesn't have the ability to search for and communicate with Skype contacts.
When directory search is enabled, you can search for and find Skype and Skype for Business users. If for some reason you can't find them by searching the directory, you can send them a contact request, and then have them sign in to Skype and accept it, so you can IM with them.
It's not possible to allow IM connectivity with other IM providers such as Google or Facebook. You can't use Skype for Business to send cell phone text messages.
It is not possible to record audio or video calls between a Skype Contact and Skype for Business contact.
What features are available when adding Skype contacts?

| Available with Skype contacts | Not available with Skype contacts |
|---|---|
| Video conversations Person-to-person instant messaging Presence | Multi-party IM conversations Audio and video conversations with three or more people Desktop and program sharing |
