Prioritizing Office 365 traffic via specific uplink with Dual WAN Connection

[TokyoKevin]

Hello.

Is there an efficient way to prioritize Office 365 traffic towards a specific WAN uplink?

I know Meraki has an SD-WAN Plus license with local breakout, but that seems to not be exactly right for this scenario, as this setup would be in a single site with no tunneling of traffic to a datacenter or other locations.

I really think that you have to go with the SD-WAN plus licence to leverage the SD-Internet ( https://documentation.meraki.com/Architectures_and_Best_Practices/Cisco_Meraki_Best_Practice_Design/... ) 

You would then choose O365 from the Major application list.

It would be painful.  You would need to add in all the IP address ranges:

as a flow preference:
