    Hi,

    If you are a sender of the Email and the recievers are getting this message(the Question is not clear I'm afraid), consider filing the request form at https://sender.office.com.

    If this is a custom domain email account, cCan you ensure if you have added the SPF and DKIM records in the Domain DNS?
