Editors Note: This web site was gently updated from the time it had been initially printed in 2018 using the latest dates around the Skype for Business phase out as it’s been announced Microsoft is ending of Skype for Business and replacing Skype with Teams.


This publish belongs to our Microsoft Teams Admin Guide series. Browse the other records within the series as they’re added below: 


In March 2017, I authored a blog publish predicting that Microsoft Teams would replace Skype for Business. However, this wasn’t formally validated until later around in the Microsoft Ignite conference.

Just when was Skype for Business Being Substituted with Microsoft Teams?

In This summer 2019, Microsoft formally announced the finish-of-existence for Skype for Business could be This summer 31, 2021. Skype for Online Businesses won’t be accessible and integration with third-party audio providers will cease.

In 2018, Microsoft boasted concerning the fact that Microsoft Teams has become at feature parity with Skype for Business Online–a essential milestone, because it implies that organisations can easily switch from Skype to Teams without having to sacrifice features.

Ultimately cutting lower the amount of tools which do similar/exactly the same things at work 365 (now Microsoft 365), for example Skype and Teams, truly does assistance to alleviate finish user confusion. However, this presents another challenge with regards to Microsoft Teams.

Microsoft Teams
Teams is Microsoft’s substitute for Skype

The thing is, Microsoft Teams isn’t just a unified communication product it’s a cooperation tool, a window into other apps and services, (or, because it is being positioned by Microsoft, an “app hub”). What this effectively means is the fact that Teams is really a single pane of glass that people communicate, collaborate, and eventually work.

Whenever you consider this poor all of those other Office 365 stack, Microsoft Teams adds an additional layer of functionality on the top of Office 365 Groups. Which means that Teams is giving Office 365 users use of SharePoint Online document libraries and functionality, OneNote, Planner, and a lot of additional features.

Getting a Skype for Business substitute having a platform that gives similar functionality along with a couple of more features is a factor, but replacing it with one which supplies a significantly bigger quantity of features is an even bigger deal.



What I’m talking about this is actually the distinction between the first migration and upgrade journey to Skype for Business from communications tools at that time, in comparison to the change from Skype for Business to Microsoft Teams. In no way shall we be held stating that Skype for Clients are simple, or it didn’t introduce additional features and methods for working. Things I am saying, however, is it is exclusively a communications tool. Microsoft Teams is a lot more.

Applying Microsoft Teams means organisations are applying SharePoint &amp OneDrive, even when they haven’t deliberately tried it yet. That’s because all of the file storage of Microsoft Teams is delivered by SharePoint &amp OneDrive. Teams users also get access to a SharePoint site and all sorts of its wonderful, modern features.

Exactly what does all of this relate to the Skype for Business client?

Well, there has been rumblings of and demands (myself incorporated) for any “Teams Lite” client that just gives people use of Skype for Business features. Although this continues to be discussed and there has been nods from Microsoft folks, it probably won’t ever happen. Why?

Because Microsoft doesn’t simply want you to definitely change your Skype for Business client – they need you to employ the entire set of features of Microsoft Teams and alter how you work.


Skype For Business Finish Of Existence Dates

Should you simply upgraded to Teams Lite client in the Skype for Business client you would not need to change behaviours around email, attachments, file shares, switching between multiple apps, or how you work now generally.

So how to proceed? Your users are becoming the entire Microsoft Teams client and all sorts of it brings by using it, regardless if you are ready or otherwise.

Among the greatest stuff that needs addressing is governance.

When individuals discuss governance with regards to Office 365, it’s usually poor SharePoint as that’s where it originated. However, within this modern world in which the Skype for Business client substitute is significantly more effective and have wealthy, governance presently has to use towards the entire Office 365 stack.

Another thing that should be considered are file shares. There isn’t any reason that you should be utilising network file shares if you are also using Microsoft Teams. Also it doesn’t mean you need to adopt SharePoint making it your intranet (although that would be amazing).

You have to straighten out how users are likely to access files when utilizing Microsoft Teams. Should you not, you’ll probably face file duplication as users unknowingly share different versions of files inside a Teams funnel, compared to version within the file share.


Prepared to Upgrade? The coexistence mode within the Microsoft Teams admin center might help.

  • Islands mode– Allow users to make use of both Skype for Business and Teams concurrently.
  • Skype for Business with Teams collaboration – Users may use Skype for Business additionally to presenting Teams for group collaboration (channels).
  • Skype for Business with Teams collaboration and conferences – Users may use Skype for Business additionally to presenting Teams for group collaboration (channels) and Teams conferences.
  • Teams only – Users are only able to use Teams, however they can continue to join conferences located in Skype for Business.

Many of the conversation about Microsoft Teams has been had by Skype for Business integrators also it pros, and that’s since the product has its own marching orders. While there’s no official sunset date, the woking platform and subsequently the Skype for Business client goes away.

As Skype for Clients are substituted with Microsoft Teams and users get their conversations around the new platform, will you be prepared for anything else they’ll be utilising?
