Office 365 Expert - I am not. I have a customer that...

Thanks Jimmy -  I agree - It's pretty much what we do's just
this one customer wanted Office 365 specific details. I don't think anyone
knows. Including Microsoft, app creator.

Wonder when Cloud providers get a clue, step up and help recommend a
circuit size based on users and the services their customer buy from them.
All that investment in co-lo infrastructure and it's left the middle man.
VCs in the cloud sector should be realizing that customer experience in
their cloud investment can be hindered as they leave this up to the
middle. But, they (and MS) should publish something other than the monthly
GB transfer/seats they charge by. Enterprise circuits are not sold by GB
transfer. After all we just want to get it right and help make the cloud
service provider's apps run well.

Thank You
Bob Evans
