Skype for Business is part of the Microsoft 365 suite of products. What's Skype for Business?

Some Office 365 plans do not include the full Skype for Business client. For these plans, Skype for Business Basic is available without additional cost.

You get the Skype for Business download from the Microsoft 365 portal, and then install it on your computer. These steps usually take 10-15 minutes to do. Choose from the instructions below.

Install Skype for Business on Windows

The Skype for Business Basic client is designed to be used on systems that need only basic functionality. It provides instant messaging (IM), audio and video calls, online meetings, availability (presence) information, and sharing capabilities.

You will need an active account to use the Skype for Business Basic client.

  • Download and install Skype for Business Basic

    When you click the Download button on the page, you will be prompted to choose the download that matches the edition of your other Office applications (32-bit edition or 64-bit edition). If you don't know, choose 32. The installer will check the edition for you.

  • If you want to deploy Skype for Business Basic to a large number of people in your business, see Deploy the Skype for Business client in Microsoft 365 for information about deployment tools you can use.

These instructions explain how to get to the Skype for Business download, and install it.

Tip: If you don't see the Skype for Business download in your portal, make sure the Microsoft 365 for business plan you purchased includes it. Also, ask the person in your business who purchased it whether they assigned a license to you.

  1. Sign in to Microsoft 365 at https://admin.microsoft.com/.

  2. At the top of your Microsoft 365 page, choose Settings: update your profile, install software and connect it to the cloud > Microsoft 365.

    Choose Office 365 settings

  3. Choose Software.

    Choose Install and manage software

  4. Depending on your Microsoft 365 plan:

    • If you see the following page, choose Skype for Business, choose your language, the edition that matches your other Office applications (32 bit or 64 bit - if you don't know, choose the default) and choose Install. Then go to step 5.

      At the first page of the Skype Setup wizard, choose your language.

    • If Skype for Business is bundled with other Microsoft 365 applications, you'll see the following page. Choose Install to install the Microsoft 365 suite of applications, including Skype for Business. When you're done, go to Sign in for the first time at the end of these steps.

      This is what you'll see if your version of Skype for Business is bundled with other Office applications.

    • If you don't see Skype for Business listed at all, then it's not included in your Microsoft 365 business plan -OR- your admin hasn't assigned a license to you. Ask your admin (the person who gave you sign-in information) for help.

  5. At the bottom of your screen, choose Save as to download the setupskypeforbusinessentryretail.exe file to your computer.

    Choose Save as to save the app to your computer.

    Important: Note where you saved the setupskypeforbusinessentryretail.exe file on your computer. If Skype for Business stops during setup, this is where you go to re-run it.

    Choose Run to start the setup wizard.

    The Office installer starts, and displays a message that it's installing Office. However, it's only installing Skype for Business. It is not installing all of Office.

    The Office installer looks like it's installing Office but it's only installing Skype for Business.

  7. When the Office installer is finished, it displays a message that Office was installed on your computer. However, only Skype for Business was installed. Choose Close.

If you have Office 2007, 2010, or 2013, you can safely install and use Skype for Business 2016. It won't overwrite your existing Office programs UNLESS YOU ARE INSTALLING MICROSOFT 365 PROPLUS. Please read all the information below before installing.

What happens when I install Skype for Business 2016 on a computer that has Office 2007, 2010, or 2013?

  • Use the instructions to install Skype for Business for the plan you have:

  • When you go to install Skype for Business 2016, you'll see this page, which indicates that you're only going to install Skype for Business:

    At the first page of the Skype Setup wizard, choose your language.

  • When you choose Install, the Office installer will start. It looks like all of Office is being installed, but it's only installing Skype for Business.

  • If you have Office 2007, Skype for Business 2016 won't be fully integrated with your Office programs. For example, you won't see the presence of your co-workers when you type an email in Outlook (by "presence" I mean you won't see whether they're available, busy, or away), and you won't have a few other features. But you will have chat (IM) and conferencing with your co-workers.

IMPORTANT: IF YOU PURCHASED MICROSOFT 365 PROPLUS YOU WILL HAVE TO UPGRADE TO THE ENTIRE OFFICE 2016 PACKAGE IN ORDER TO GET SKYPE FOR BUSINESS. IT WILL OVERWRITE PREVIOUS VERSIONS OF OFFICE. When you go to install Skype for Business, you'll know you have Microsoft 365 Apps for enterprise because you won't see an option to install Skype for Business by itself; you'll see this instead:

This is what you'll see if your version of Skype for Business is bundled with other Office applications.

If you don't want to upgrade to Office 2016, talk to the person who purchased your Microsoft 365 Apps for enterprise plan to see about getting a standalone Skype for Business Online Plan subscription.

Important: If you upgrade from the Microsoft 365 Mid-size or Microsoft 365 Small Business Premium plans to Microsoft 365 Apps for business or Microsoft 365 Business Standard plans, Skype for Business will be removed from your computer. You have to install Skype for Business Basic to get the functionality back. Learn more.
