Feedback on Office 365 IP/URL Web Services Preview

Paul,

I've written myself a PAC file generator which includes the URLs in the Allow and Optimize categories.

I have a question regarding "ExpressRoute" which my company does not use at present. The list of URLs in Allow and Optimize for non ExpressRoute is as follows:

o15.officeredir.microsoft.com

ocsredir.officeapps.live.com

officepreviewredir.microsoft.com

officeredir.microsoft.com

r.office.microsoft.com

ea-000.ocws.officeapps.live.com

eus2-000.ocws.officeapps.live.com

ncus-000.ocws.officeapps.live.com

neu-000.ocws.officeapps.live.com

ocws.officeapps.live.com

scus-000.ocws.officeapps.live.com

weu-000.ocws.officeapps.live.com

wus-000.ocws.officeapps.live.com

eus-odc.officeapps.live.com

ncus-odc.officeapps.live.com

neu-odc.officeapps.live.com

odc.officeapps.live.com

scus-odc.officeapps.live.com

sea-odc.officeapps.live.com

weu-odc.officeapps.live.com

wus-odc.officeapps.live.com

ea-roaming.officeapps.live.com

eus2-roaming.officeapps.live.com

ncus-roaming.officeapps.live.com

neu-roaming.officeapps.live.com

scus-roaming.officeapps.live.com

sea-roaming.officeapps.live.com

weu-roaming.officeapps.live.com

Only in other endpoint sets where ExpressRoute is true do you get other URLs which need to go DIRECT e.g. in endpoint set 46:

*broadcast.officeapps.live.com

*excel.officeapps.live.com

*onenote.officeapps.live.com

*powerpoint.officeapps.live.com

*view.officeapps.live.com

*visio.officeapps.live.com

*word-edit.officeapps.live.com

*word-view.officeapps.live.com

office.live.com

Are these not required to go DIRECT when not using ExpressRoute?

The URLs are listed as to go DIRECT in the PAC file described in the Managing Office 365 endpoints web page.

Also Endpoint set 11 has IP addresses and UDP ports 3478,3479,3480,3481 which need to route DIRECT but are listed as ExpressRoute.

Can you please clarify the use of ExpressRoute in the web service? Do I need to include all Allow and Optimize endpoint sets regardless of the ExpressRoute setting?

Thanks
