Hey there! You mentioned the issue happens with Outlook - does the same problem happen when you send a message from Webmail?

From webmail we can send a message, only from Outlook we received the error

That's odd, but at least confirms the issue isn't an IP reputation problem or something on the server side.

When the message is marked as spam, does it give any other details in the bounceback you receive? At this point it sounds like a problem with Outlook, so there may not be much you can do on the server side to resolve the issue, but we would need more details to help troubleshoot.
