• Any Visual Studio subscription
  Requests to remove these restrictions won't be granted.

The statement from Microsoft is pretty clear.

Hi @Khaled Laghrour ,

maybe this helps: https://learn.microsoft.com/en-us/azure/virtual-network/troubleshoot-outbound-smtp-connectivity

Depending on the type of subscription it's possible to get the port 25 communication allowed.

What kind of subscription do you have?

You won't get the port 25 communication granted on the following subscription types:

• MSDN
• Azure Pass
• Azure in Open
• Education
• Azure for Students
• Free Trial
• Any Visual Studio subscription
