M365 Changelog: Skype for Business online contacts retirement

Rabia Noureen


MC349675 – With Skype for Business Online retired on July 31, 2021, Microsoft will soon be commencing the decommissioning process of the supporting infrastructure no sooner than June 30, 2022.

Key points:

  • Timing: June 30, 2022
  • Action: review and have upgraded users take action as appropriate

How this affects your organization:

Any users in your organization that were upgraded from Skype for Business (either online or on-premises), may need to take one or both of the following actions:

Actions Required:

  1. If these upgraded users had contacts in Skype for Business Online and have not yet logged into Teams since being upgraded, they must log into Teams at least once before June 30, 2022, to ensure any contacts from Skype for Business are migrated to Teams.
  2. If these upgraded TeamsOnly users still have Skype for Business Online meetings that they organized before they were upgraded to TeamsOnly, then before June 30, 2022, these users must either reschedule their remaining Skype for Business Online meetings as Teams meeting, or an administrator in their organization must convert these meetings to Teams meetings using the Meeting Migration Service. After Microsoft removes the Skype for Business Online infrastructure for a given TeamsOnly user, any remaining Skype for Business Online meetings organized by that user will no longer exist and hence will not function.
