Lync Mobile Client not showing User’s Numbers



one of the problems was looking around for a fix for it was when you open the contact card of a user in your Lync Mobile client, you cannot see his/her Mobile number, and some time the office number.

the work around recommended but not efficient was to add the missing number to the affected  contact details in the Outlook.


So other than the case that you had set your privacy level to a higher level than default one “External Contacts or Colleagues”, which will result in not sharing your office / mobile details with other contacts you can fix the problem now by applying the new Lync 2013 Server CU5 released yesterday


After applying the update to my infrastructure, it fixed this problem, plus other problems that you can read more details about in the KB article of the update mentioned above.
