Hi Prajwal, I'm very new to SCCM 2012R2 and o365, through your web site and your expertise on SCCM i was able to set up SCCM for the organization i work for. My organization has business subscription of E3 o365 licenses. All users at this time have office 2013. How would i go about upgrading all users to office 2016/o365 via SCCM R2, using the click-to-run method? Your assistance would be most grateful, I'm a newbie to o365 and SCCM, so any help would be great.
