Cannot add, remove, or move contacts or groups at this time in Lync 2013

Brian Hadfield -

When attempting to add contacts to your Lync contact list you receive the following error:


There are a number of different causes for this error, but the most common solution is to delete the SIP profile for the Lync user.  To delete the SIP profile for a user on a Windows workstation, follow the guidance below:

Deleting the SIP Profile

  1. Close Lync completely by right-clicking the Lync icon in the Windows System Tray and selecting Exit.
  2. Open Windows Explorer and navigate to the folder that corresponds to the Lync client version that is installed
  • Lync 2010: %UserProfile%\AppData\Local\Microsoft\Communicator
  • Lync 2013: %UserProfile%\AppData\Local\Microsoft\Office\15.0\Lync
  1. Delete the sip_username directory that matches the sip address of the user experiencing the issues.  This directory will be rebuilt when the Lync client is restarted the next time.
  2. Restart the computer
  3. Restart the Lync client

The SIP profile folder and cached information will be rebuilt and the issues above should be resolved.
