jaward916 -> 2007/2013 coexistance internal email not working (26.Jan.2016 8:12:27 AM)

HI all,

I have an issue with internal mail between a physical 2007 box and a cloud hosted exchange 2013 box (the vpn between the 2 has all ports available).

What I can do is:
2007<-->2007
2013<-->2013
2007<-->external
2013-->external

but not
external-->2013
2007<-->2013

Therefore I'm thinking "Receive Connectors" and therefore I'd like to know if anyone has any sample receive connector both 2007 and 2013 side that does work between the 2??? I'm really stuck

From 2013 to 2007 I get 5.7.1 Exchange Authentication related error
from 2007 to 2013 I get 4.2.1 Not Found error

When I do a telnet test from 2007 to 2013 on port 25 it fails miserably, but if I do on port 2525 it works as it should, so how do I get my 2007 server to forward mail to the 2013 using port 2525?

Thanks in advance
