I am thinking of using expressroute for are remote users to access Office 365. Has anyone set it up within a VPN environment?
Have a few configuration questions regarding services used to connect to it. Please reply back and I will ask away.
I have a bit more narrative to the question.
Does it support point to site connectivity, such as listed in the example below to our tenant?
Has anyone deployed it successfully?
The main question is why do you think of using ExpressRoute, what benefit are you trying to gain?
ExpressRoute is only for scenarios where customers need a private, direct connection to Office 365 because of regulatory reasons. ExpressRoute will be established between a disctinct customer location using MPLS connectivity from a local telco - so a Remote User can not simply ExpressRoute as with P2S VPN. A remoteuser could use P2S vpn to dial in to the company HQ and from there use ExpressRoute.
Generally, ExpressRoute for O365 is not a recommend option for every customer, it should be avoided unless there is a very specific scenario where ExpressRoute is absolutely needed.
See also https://docs.microsoft.com/en-us/office365/enterprise/azure-expressroute for more information on the effort to set this up (only be approval from Microsoft) and shortcomings since you never can tunnel every connection attempt to ExpressRoute.
