    Thanks for the share Anand…

    Though this is a known story, your way of putting it with the pictures makes it easier for people to understand and to get it done.

    Now that the installation is complete, reporting becomes an issue, you know, reporting with O365 is always a pain. Monitoring O365 usage and insights in a multi user or multi license environment is yet another pain, especially for an MSP like ours.

    Since you are an expert in this aspect, do you know any solution or a tool to monitor and report O365 without any hassle?

    Just bought this Laptop as a planned gift. Office 365 does not come with a CD, so have to try to install that Software using the Product Key. Have set-up a Microsoft Account but Microsoft does not seem to recognize it yet so I can not get to the “Install” Button at all. Is there a delay before a new Microsoft Account is Activated for installation of Office 365? I logged a Support Chat Call of course but have been waiting for about 3 Hours so far!!!
