Lies and Trust
What I find peculiar is the attempt to blame a handful of over-enthusiastic people whose only error was to believe that unlimited meant what it said.
I don't use any form of cloud storage for anything at all important. I was quite pleased with the idea of unlimited storage as part of office 365, as a sensible admission of the obvious, but have actually used (checks up) around 2Mb of it so far.
But without actually causing me any harm at all M$ have completely undermine my recently recovered trust in them, W10, and Office, as sensible ways to use a computer. It has taken me many years to be comfortable using them again, and after a few months they have kicked me firmly in the bollocks.
I have alternatives.
