I have posted additional articles here and or in the Office 365 Forums regarding pre-upgrades procedures that MS has made to some of my customers tenants that have changed behaviour. Now, MS has stated repeatly that they haven't changed anything even though some of these changes are graphically visual as well as behavior changes.

 So, I wanted to adv>

I thought this would be useful and I  have also written to BB Support (RIM) that they should also add this to their guidance. Because, if you write to them questioning about  the setup with BB 10 Devices they'll send you this link: http://www.blackberry.com/btsc/KB33522
I will also post in the Office 365  forum - so others don't waste some of the time I did & finally got it to work on a last ditch effort.
