hybrid 2016 exchange with 2013 exchange - Relay Issue

Hi All,

We have a hybrid setup with exchange 2016 and Exchange 2013 as we migrate. Were having an issue with relay from our internal scanners. They are able to send email internally but not externally. We have dns pointing to the 2016 server and we see the IP's in both Relay connectors on 2013 and 2016 email servers. However it wont send external from scanners, the error is invalid recipient on the scanner. However if we change the scanner to point to the 2013 server it works.  Anyone come across this situation or have any thoughts. Thanks Much

Hi Jaya31,
I had similar situation (with printer) in Exchange 2010 and 2013. I enabled authentication on the printer and it worked for both internal and external users.

Thanks

Have you validated your connectors in EXO yet?  If not and they fail, that could be a reason why, and the error message could be insightful to troubleshooting.
