- Reschedule Skype for Business Online meetings. Because of the way that the Skype for Business Online service generates meeting URLs, any meetings that were scheduled by using the old Skype for Business Online SIP address must be rescheduled. If these meetings aren't rescheduled, meeting participants may receive an error message when they try to join any Skype for Business Online conferences that are scheduled by that user.
- Communicate changes to external contacts in Skype for Business Online contact lists. External contacts (this includes other federated Lync organizations), Windows Live users, and MSN users must be notified about the change to the user’s SIP address. Until external contacts remove and update the old contact, the contact object for the user is displayed as either Presence Unknown or Offline.

Review the following Knowledge Base article to make sure that the values in Office 365 aren't in conflict with on-premises values:
