Problem

Lync For Mac 2010 Free

When you try to edit your contacts in Lync 2010 or Lync for Mac 2011, you receive one of the following error messages:

Solution

To resolve this issue, the Lync admin should use the Invoke-CsUcsRollback cmdlet to roll the user back from Unified Contact Store (UCS) mode.

Notes

If your users will be using Lync 2010 or Lync for Mac 2011 as their primary client, then run the cmdlet.
If you use this cmdlet with the -force switch, you run the risk of disconnecting your users from their contacts.

For more information about the Invoke-CsUcsRollback cmdlet, see Roll back migrated users in Lync Server 2013.

Workaround

To work around this issue, use Lync 2013, Outlook Web Access 2013, or Outlook to change your contact list.

Or, you can roll back the user's contacts to Lync Server and users will then be able to change their contact list. To do this, see Lync contact list is empty or read-only after a user's Exchange mailbox is disconnected, unlicensed, or moved.

More Information

On Windows, to confirm if a user is enabled for the UCS, right-click the Lync icon in the notification area to open the Lync Configuration Information screen. Look for the Contact List Provider line. Either UCS or Lync Server appears.

Lync For Mac 2011

This issue occurs because the user's contact list was migrated to the Exchange UCS. This is a new integration feature of Exchange Server 2013 and Lync Server 2013. After the migration, the user's contact list provider changes from Lync Server to UCS.

Microsoft Lync 2010 For Mac

Even though Lync 2010 and Lync for Mac 2011 can read the UCS contact list, they can't change contacts or groups in the UCS. Therefore, users who are enabled for the UCS can't change their contacts list from Lync 2010 and Lync for Mac 2011.
