Reschedule any futureand recurring LyncOnline meetings.
If the name part of the address has changed (that is, from rdesforges@domainname to remi.desforges@domainname, then the user has to update his or her LyncOnline meetings by resending the invitation. This requirement is because the Lync meeting link changes. If users do not update their meetings, then users joining the meeting will see an error message.
Communicate changes to external contacts in LyncOnline contact lists.
External contacts, such as other federated Lync organizations, Windows Live users, and MSN users must be notified about the change to the user’s SIP address. If external contacts do not make this change, the contact card for the affected user will simply remain as either Presence Unknownor Offline.
