I am needing some assistance in the best way to create an ACL or some network-object group for all the Office 365 URL's and IP's that go into running the different features. We have a proxy device that is getting hammered due to it not being large enough of a device to handle all the additional traffic that comes with O365. We have an interface that we can bypass traffic so that it does not hit the proxy. I was trying do it in the ADSM but it takes forever and was wondering if someone has a better way to get all the O365 traffic URL's and IP's groups created especially with them changing them regularly. I can't remember the command line for creating a Network object group. Anyone have any suggests on how to get this done quickly or the best way to handle this issue.
An example of a few of the O365 URL's and IP's that I have to deal with.
