QoS for Office365

[Joe Yabuki <joeyabukiyin () gmail com>]

Hi all,

How do you deal with QoS for Office365, since the IPs are subject to
changes ?

How can we mark the trafic while keeping the security (I fear the marking
based on TCP/UDP Ports since they are not without an additional risk coming
from worms/virus using those ports for example, and doing that directly on
the PCs doesn't seem to be the best solution) ?

Many thanks,
Joe
