Here's a question I can't find answer to anywhere in documentation:
Let's say I use either of these options:
- Site-to-Site VPN connection over ExpressRoute private peering
- Configure a site-to-site VPN over ExpressRoute Microsoft peering
- IPsec over ExpressRoute for Virtual WAN
How will price for egress traffic be calculated? Will I be charged twice - once for VPN Outbound Inter-virtual? Data Transfer and once for ExpressRoute Outbound Data Transfer? Or just for one of them? For which then?

Ideally, there should be two separate billing as ExpressRoute connection is not aware of the VPN Gateway Tunnel Traffic.
However, I see
When you set up site-to-site VPN over Microsoft peering, you are charged for the VPN gateway and VPN egress. For more information, see VPN Gateway pricing.
in the Notes section of Configure a site-to-site VPN over ExpressRoute Microsoft peering
I shall confirm this internally and update this thread shortly
Cheers,

To get more clarity, we will need a specialized 1:1 session, where a support engineer can check the backend logs to pinpoint the issue. If you have a support plan you may file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.
Cheers,
Kapil
