You install the cumulative update that is mentioned in Microsoft Knowledge Base (KB) article 251482 or later on each Lync 2010 client in an environment.
You have user A and user B in the environment.
User A uses Outlook to set user B as a delegate for user A’s mailbox. User A also uses Lync 2010 to set User B as a delegate.
User B creates an online meeting email message on behalf of user A. To do this, user B selects the meeting time on user A’s calendar. Then user B clicks the New Online Meeting button in the ribbon of Outlook or clicks the Online Meeting option in the New Items drop list.
In this scenario, the user name that is included in the meeting URL belongs to user B instead of user A.
