Hi, we have been with BT for about 10 years (for better or for worst) we have an SBS 2011 with exchange 2010 that I setup 5 or so years ago and the exchange server is capable of receiving and sending emails fine, no problem whatsoever. last week we migrated to a new windows 2012 r2 server and a new exchange server, we migrated the active directory, dns, exchange 2016 etc and everything seems to be fine and we can send emails internal and external with no problem, HOWEVER I noticed on Friday that if I shutdown the old server (as I will have to do in 21 days when the grace period ends ) the external emails go no where...I have try everything I know about send connectors and try as many configurations as possible but it is impossible....Called BT a couple of times one I was left waiting for a call back inside 3 hours and the other one, the guy told me that it could not help me...
I did not change the domain or the pointer, I only changed the name of the server...
Is there any one that can tell me what I need to do to get the new server to send emails through BT as it happens with the old server?
Thanks a lot for the help.
