I do IT support for a smallish business.
We moved all our server mail and file storage onto Office365 5 or 6 years ago and this works great.
So we have our own email domain name but that's all.
When I set up a new user I just create their account in office 365 and for the PC/Laptop I just create a local user.
The user can then log into office 365, install the office apps, access sharepoint etc and it all works fine.
But MS is getting very annoying about wanting a 'Microsoft account' on devices and you have to really fight to break into the bit that lets you create a 'local account'.
A "MS account" is not an "Office 365 account". So you cant create a user account on the PC with the Office 365 address.
There must be other people in a similar situation - how are you handling this???
One support place I spoke to suggested I could do a clean install of windows on any new hardware that Rufus had been used on to clobber the Microsoft account nags. That seems pretty harsh.
Any advice happily accepted - but keep it simple!
