One of our guys came up across this error recently on a system we have been developing for one of our clients. It's not en error that I have seen before so I thought it worth mentioning. The full error was:
The InboundTransportLocation is disallowed. This could be because the receive location is disabled or its service window is currently inactive.
It took us a bit to figure out (i think about 10 minutes combined), and it turns out that the document that we were receiving was invalid and we were using an XMLReceive pipeline with the
AllowUnrecognisedMessage property of the pipeline set to
False.
So, yeah, this was the correct message. Ideally, this is a scenario you don't run in to much, as in the perfect world you always receive valid documents. I guess we all know that is a bit of a pipe-dream.
