Permitting access to Office 365

[glydeen]

Very new to Meraki and how Meraki handles Firewall rules etc...

I need to create a segment on the network blocking all outbound access except for what I explicitly allow. I am looking for advice on how to handle allowing access to Office 365.

Do I need to create a policy Object and include all the FQDN's for Office 365 (The lengthy list), or is there a simpler approach?

Any advice would be appreciated.

You could do that.  You could use do contenting filtering, block "*" and then whitelist the URLs allowed.

Another less accurate approach but easier to configure is to use content filtering categories on the VLAN, and filter pretty much every category except for the one used by Office 365 (probably business something).
