Hello,

Any chance you are trying to send an email with a PDF attachment?

More and more email services providers have updated their spam filters due to rising zero-day phishing PDF campaigns. PDFs + HTML email are commonly used in phishing, so security systems scrutinize these more.

You can consider these alternatives if you need to send PDF attachment -

1. Share it via a OneDrive link instead for the recipient to download.
2. Zip it into a .zip file and attach it.
3. If your email format is rich text/html, convert it to plain text. Instruction can be found here: https://support.microsoft.com/office/change-the-message-format-to-html-rich-text-format-or-plain-text-in-outlook-338a389d-11da-47fe-b693-cf41f792fefa
