I've setup in the Global policy a custom disclaimer , subject and ticked the box that says use a custom logo (I can see our company logo). All is sent via the notification except for the company logo. Instead we get the Office 365 logo. Is this a bug or is there another way to force it to change?

In an Anti-Phishing policy (e.g. "O...
