Recently at Microsoft Ignite, I co-presented with my wife Megan Strant on some of the challenges we’ve come across over our many years working with Office 365 across hundreds of customers of all sizes, industries, and countries.
You can catch the audio-only recording of our 20 minute theatre session online as well as download the slides here: https://myignite.techcommunity.microsoft.com/sessions/80262
AvePoint provided a great writeup of the session here: https://www.avepoint.com/blog/office-365/office-365-avoiding-icebergs/
What I would say is that a lot of the points we cover may seem obvious, but I am personally alarmed on a regular basis how many times I come across organisations that fit into many of the covered topics.
