Lync Online Office 365 How to Add or Modify Dial In Conferencing Numbers

Dialin Conferencing numbers are assigned via the “Lync Online Control Panel”. For a single user go to the  Microsoft Online Portal, navigate to the Lync Online management tool, and then go to User management. To assign a single user, select the user and open their Lync properties. At the bottom of the configuration screen, you can select an audio conference provider and type in phone numbers and passcodes for the provider (note: it is important to enter only the numbers as the screen shot shows and avoid any dashes, dots, or parenthesis). Save the user profile. If adding bulk users or need additional information on the above procedure refer to: http://community.office365.com/en-us/wikis/lync/1715.aspx
