In my position, I need to do some Administrative tasks in Office 365. Office 365 got a very user-friendly interface to config the Office 365 products, from Calendar to Sharepoint Online. However, for advanced administrative tasks, I need to use Powershell script. Such as unlocking composited looks in Sharepoint and Change the permission of a room's calendar. Thus, as an Office 365 Admin, I have to learn Powershell. I need to watch more tutorial video from Plursight.
