-->Introduction
This article contains information about how to troubleshoot Lync for Mac issues in Skype for Business Online (formerly Lync Online). It also discusses how to sign in to Skype for Business Online by using Lync for Mac and how to collect log files and system information for Lync for Mac issues.
Procedure
Before you troubleshoot
First, make sure that users follow the correct steps when they sign in to Skype for Business Online. If users are signing in to Skype for Business Online correctly and the issue persists, use one or more of the other methods later in this article to troubleshoot the issue, as appropriate for your situation.
Note
To connect Lync for Mac 2011 to Skype for Business Online in Office 365, you must have Lync for Mac version 14.0.6 or a later version installed. If you use a version that's earlier than version 14.0.6, you may have problems when you sign in to Skype for Business Online because earlier versions have issues that prevent authentication to Skype for Business Online. You can find the latest update at Update for Lync for Mac 2011.
Make sure that users follow the correct steps when they sign in to Skype for Business Online
To sign in to Skype for Business Online by using Lync for Mac, users should follow these steps:
Start Lync for Mac.
Enter your email address, user ID, and password.
Next to Sign in as, select the presence status that you want to display after you sign in.
If you want to save your credentials, click to select the Remember my password check box. Your credentials will be saved in the Mac OS Keychain and will work until the next time that your password changes or expires.
To configure additional options for connecting to Skype for Business Online, click Advanced. You can configure the following options:
Automatic Configuration: In most cases, this is the correct setting. If the necessary DNS records are present and automatic configuration isn't working, try Manual Configuration.
Manual Configuration: Select this option if automatic configuration is failing, and specify the following values:
- Internal server name: sipdir.online.lync.com:443
- External server name: sipdir.online.lync.com:443
Kerberos authentication:Leave this option cleared. Office 365 uses the Microsoft Azure AD authentication system for authentication.

Troubleshoot Lync for Mac issues
Use one or more of the following methods, as appropriate for your situation.
Users may be unable to sign in unless they first use an incorrect sign-in address
Try to sign in to Skype for Business Online by using an incorrect sign-in address. That is, a sign-in address that you know won't work. For example, EmailAddress @contoso.com.
Note
When you do this, sign-in will fail. This is expected behavior.
After the sign-in fails, sign in by using the correct sign-in address. For example, EmailAddress@contoso.com.
If Lync for Mac stops working after an Internet connectivity issue, flush the DNS cache
To flush the DNS cache, do one of the following, depending on the version of Mac OS that you're running:
- If you're running Mac OS X 10.5, Mac OS X 10.6, or Mac OS X 10.7 Lion, start Terminal, and then run the following command: dscacheutil -flushcache
- If you're running Mac OS X 10.4 Tiger, start Terminal, and then run the following command: lookupd -flushcache
Clear cached data and corrupted certificates in Lync
First, delete the following folders:
- Users/Home Folder/Library/Caches/com.microsoft.Lync
- Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync History
Then, delete any corrupted or cached certificates. To do this, follow these steps:
Open the Keychain Access certificate management utility. To do this, in Finder, click Applications, click Utilities, and then click Keychain Access. Or, search for Keychain Access by using Spotlight.
In the left pane, click login, and then click Certificates.
In the right pane, find a certificate that's named Unknown or Communications Server, select it, and then delete it.
Note You may have to unlock your keychain by using your password.
Close Keychain Access.
Restart Lync for Mac.
Important
Microsoft Lync Mac Login Account
Before you perform the next step, try reproduce the issue by using a new test user account. If the issue doesn't repeat in the new account, then follow these steps:
Open Keychain Access Preferences, and then click Reset My Default Keychain.
Open Finder, locate the following folders, and then delete them:
/Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync Data
/Users/Home Folder/Documents/Microsoft User Data/Microsoft Lync History
Federated users synchronized from on-premises Active Directory Domain Services can't sign in by using a password that's longer than 16 characters
Organizations that have on-premises customer password policies may allow for passwords to exceed 16 characters. By default, the password policy in Office 365 restricts passwords to 16 characters or less. Because of the Windows Challenge/Response (NTLM) authentication mechanism in the Mac OS, passwords that are longer than 16 characters aren't recognized correctly, and this causes sign-in to fail.
To work around this issue, the user should change his or her password to be 16 characters or less.
Lync for Mac crashes and the user receives an EXC_BAD_ACCESS error
This error message usually occurs when Lync for Mac tries to integrate or schedule meetings with an Exchange mailbox that isn't hosted in Exchange Online. This scenario isn't supported in Skype for Business Online. For the best experience, you should use both Skype for Business Online and Exchange Online. However, if that isn't an option, follow these steps as a potential workaround:
Microsoft Lync Download
Open Finder, locate the following folder, and then delete it:
DocumentsMicrosoft User DataMicrosoft Lync Data
Start Lync for Mac, and then sign in to Skype for Business Online.
On the Lync for Mac menu, click Preferences, click Account, and then clear the Use Microsoft Exchange for managing personal information check box.
Note You must perform step 3 quickly after you sign in.
