Hello,

I hope someone can help me out here.

some background info:

I have several sites with CAS servers in it and only one site is internet facing.

I enabled the calendar publishing on all owa vdirs. The external url is only set on the internet facing CAS server.

I published the external url via a Kemp Loadmaster. Access from external to a published calendar is working IF the mailbox is located in the internet facing site.

If the mailbox is located in a non internet facing site I got a 404.

I assume that I miss a little thing here, something with cas proxying or redirect?

Thanks for your help an time

Chris
