Microsoft Teams Move to Replace Skype for Business Online Starting October 1st 

October 1, 2018 – Microsoft recently announced that the roadmap for bringing Skype for Business Online features and functionality to Microsoft Teams is now complete. Starting October 1st, Microsoft Teams will replace Skype for Business Online for all new customers. New Office 365 customers with 500 seats or fewer will be onboarded to Microsoft Teams and will not have access to Skype for Business Online. Tenants already using Skype for Business Online will be able to continue doing so (including provisioning new users) until they complete their transition to Microsoft Teams. Beginning November 1st, Microsoft will offer partner-associated customers automatic upgrades from Skype for Business Online to Microsoft Teams. Tenant Administrators will be notified through email and the Office 365 Message Center. 

More than 200,000 organizations are using Teams, including nearly 70% of enterprise customers who use Skype for Business Online.  IT administrators can begin the process of moving their users off Skype for Business Online by setting Microsoft Teams as the default communications client for Office 365.  

What Does This Mean? 

This announcement affects organizations differently depending on how they currently use Office 365: 

  • Organizations below 500 employees who are currently looking to deploy Skype for Business Online will now only be able to deploy Teams.    
  • Any organization currently on Skype for Business Online (without Enterprise Voice) can continue using Skype for Business (and adding users) regularly.  However, starting November 1st, these organizations will be upgraded to Teams over the coming months. 
    • Organizations not interested in automatically upgrading will receive information on how to disable the upgrade. 
  • Organizations currently on Skype for Business Online with Enterprise Voice functionality can continue using Skype for Business (and adding users) regularly.  These organizations will not be moved to Teams starting November 1st.   
  • For organizations on Skype for Business Online that plan to upgrade to Teams, there are two things to consider: 
    • If you are not comfortable with the upgrade process, reach out to a Microsoft partner who specializes in both Skype for Business & Teams, like PEI. 
    • End-users will need training on Teams, which functions differently than Skype for Business Online in several ways. 
  • Organizations over 500 employees currently looking to deploy Skype for Business Online will still be able to but may want to consider Teams as it will eventually be the primary communications tool in Office 365.  
  • Organizations moving to Teams must be aware that there is not complete feature parity with Skype for Business Online.
