Install Online Services Sign-in Assistant

We are now ready to install the software prerequisites.

Since this PS Proxy is going to be used to manage the cloud components we are going to need the Online Services Sign-in Assistant, Azure Active Directory Module for Windows PowerShell, and Skype for Business Online, Windows PowerShell Module, and any prerequisites required by these modules.

1. Download the Online Services Sign-in Assistant (msoidclil_64.msi) and the Skype for Business Online, Windows PowerShell Module (SkypeOnlinePowershell.exe) from the links in Required Management Software and Prerequisites and copy it to the PS Proxy.
2. On the PS Proxy navigate to the folder where you copied the installer. Double-click msoidcli_64.msi to launch it, then follow the on-screen instructions.
