Skype for Business is part of the Office 365 suite of products.

    

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

  

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  Office 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 Office 365 at https://portal.office.com/.                            

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

                        

    Choose Office 365 settings

                                          
  3. Choose Software

                        

    Choose Install and manage software

                                          
  4. Depending on your Office 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 Office 365 applications, you'll see the following page. Choose Install to install the Office 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 Office 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. 

                                          
  6. After the setupskypeforbusinessentryretail.exe file has downloaded, choose Run.  

                        

    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.            

  8. Launch Skype for Business. At the First things first box, if you accept the licensing agreement, choose Accept.  

  9. You can install Skype for Business on up to 5 PCs.
