Answer 2

Hello @Yasser El Attar ,

Outbound email messages that are sent directly to external domains (such as outlook.com and gmail.com) from a virtual machine (VM) are made available only to certain subscription types in Microsoft Azure. Outbound SMTP connections that use TCP port 25 were blocked. (Port 25 is primarily used for unauthenticated email delivery.)

Please refer to the below article to know more about the port 25 availability in various Azure subscription types:

If your subscription is blocked for port 25 outbound communication, then you need to contact support to unblock it.

Kindly let us know if the above helps or you need further assistance on this issue.
