This Extended service will populate a Skype for Business contact list with all of the currently activated Skype for Business/Lync users on the account. Sometimes Skype/Lync doesn’t display updated contacts properly, in such cases this request will fix the issue.

Note: This request works only for accounts with less than 30 Skype for Business users. If there are more contacts than this, the case created by submitting this request will be closed.
