Salvatore's suggestion is spot-on, but there might be also other factors involved here, which we can only guess about without having at least looked at the message headers. It's best if you open a support case and have this properly investigated. Contacting the other party and ask them to do the same on their end, as the issue might be something outside of O365 entirely.
