'And while the retirement of Skype for Business Online has us a little nostalgic, we can’t be more excited about how Teams helps our customers accomplish more across work, school, and life.' 'Organizations that have completed their transitions can attest to the transformational benefits Teams brings,' Microsoft wrote. However the company notes that support for third-party audio conferencing providers (ACP), Skype for Business Online Cloud Connector Edition (CCE), hybrid voice configurations, and Skype Meeting Broadcast will not be continued beyond July 31 2021. 'Regardless of whether an organization manages all aspects of the upgrade or use the assisted process, our guidance includes steps to ensure meetings and contacts are successfully migrated from Skype for Business Online to Teams.' Microsoft adds that users will be able to migrate their Skype for Business Online Meetings and Contacts over to Teams, so there's no need to worry about anything being lost. Any organizations that are scheduled for assisted upgrades after Jwill still be able to use Skype for Business Online until their upgrade is complete.
