Emails Owncloud

Hey there,
i have a Probleme.
We are using Exchange 2016. I can send Email from Owncloud just local.
Everything out of our domain isnt possible.
On our Firewall are all needed ports free.

So our Cloud is Hosted by a extern System house.
they cant help because they only host stuff :confused:

So had someone the same issue?

Have you asked your Exchange admin to check the logs?

You have to allow relaying for the owncloud IP address
