Thanks Frank... I do have a customer with 500 meg/sec service running 350 meg/sec average all day.... just 800 employees - no company driven focused use of MS office 365. Applications used and time of day, etc. So, I don't think one can compare a college's overall app bandwidth usage to a business primarily using office 365. I'm really looking for a "minimum bandwidth recommended requirement for 100 employees all using Office 365 hosted docs that are all outside the LAN. " MS has no such number. MS just leaving it to the individual case-by-case discovery process. I bet Microsoft can't answer that simple question or they wouldn't have these GB per user equations that use X for average document size. Best, I have to go on so far is what one of our customers "thinks" is needed. Thank You Bob Evans CTO

1 Mbps/user seems very high -- the local college has over 200 employees using O365 (and over 1400 students) and its broadband connection is just 250 Mbps and they're at less than 150 Mbps during the day.

Thanks to those of you that answered...It is hypothetical....However, I found another customer that uses Office 365 heavily ... said they discovered 1 meg/sec per Microsoft Office 365 user works well in most scenarios. This customer has 80 users and a 100 meg/sec connection with us.

Thank You Bob Evans CTO

I have a customer that heavily uses Microsoft Office 365. It's hosted. All the data I see about usage per user appears theoretical. In that the formulas assume people are taking turns using the bandwidth as if there is a patient line of packets at the Internet gas pump. Nobody is clicking at the same time. We all know that is not the real world.

Does anyone have any experience with Office 365 hosted that can tell me the practical bandwidth allocation (NOT in KB per month, but in megabits/sec) for 100 users (during normal work hours) needs to be available ?
