If we talk about mobile services, Microsoft is in an even more difficult situation than mobile devices.
Almost 99.999..% of people use Google Maps. Many people use Google search and "google" has become a word in dictionary. Many people have a gmail account but not an outlook one.
More and more people are using Google Docs, Google Forms instead of Office 365. Especially the younger generations. I have a class of high school students having Office 365 (offered by my school) installed on their Windows tablets and most of them use Google Docs everyday despite Office 365 offer more complete features. Many online e-learning services (e.g. Kahoot!, Nearpod) offer signing in with Google account but not Microsoft account.
It seems that Microsoft services are only safe in the enterprise. They are not anymore in the consumer space. I hope Microsoft is aware of the situation.
