The Azure Active Directory Sync tool (aka DirSync) already has been setup here to synchronize on-premises Active Directory users to Office 365.
Assigning license within Office 365 admin center portal for one user is quite easy but doing this for 500-1000 users will be a time waste.
I need some help with bulk assigning Office 365 licenses based on AD group membership. Also, not all services from the licence plan will be available to the users. Some of the users (around 20-30) already have Office 365 licence, so we need to be careful not to overwrite their existing Office 365 license.
Microsoft Online Services Sign-In Assistant and Azure AD Module already installed on my Windows 8.1 workstation. Or, I could use DirSync server if I need too.
I can Connect-MsolService with my Office 365 global admin account without any problem.
Ideally I would like to have “step by step” approach with clear explanation if possible.
Thanks for your help in advance
