Thank you, you've gotten further than I have. On my "quarantine" I can't find anything (it's empty) therefore I can't also check what's going on. But "URL detonation reputation" is consistent with the behavior we're observing. |

It might be worth it to pony up for an M365 license or two, send yourself an email, and then open a support ticket inquiring why the email was blocked. I would even avoid mentioning that you are the sender. Just pretend you're a regular customer who receives email from your domain and you're wondering why it was blocked and if there's anything that can be done to stop it from happening.
