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:

1. 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.

2. In the left pane, click login, and then click Certificates.

3. 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.

4. Close Keychain Access.

5. Restart Lync for Mac.

Important

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:

1. Open Finder, locate the following folder, and then delete it:

2. Start Lync for Mac, and then sign in to Skype for Business Online.

It is possible to configure your Skype Business Server 20105 environment to establish a federation with Skype to enable users to search and to add Skype users directly in their contact lists.

The federation enabled Skype business users can add a Skype contact by using several methods of research as the full name (can also specify a location), an email address, a phone number or Skype ID.

The current Skype federation supports the following features:

• A Skype user can add user Skype business in its list of contact
  
• A Skype business user can add a Skype contact
  
• Presence
  
• IM
  
• Audio call P2P using the codec SILK
  
• Video call P2P using the codec H.264
