Message blocked because it contains content identified as spam. AS(4810) - PDF issue

I am trying to send a PDF attachment and I keep getting the message that it's been identified as spam. I haven't had this issue until tonight, and PDF attachments worked 24 hours ago. This is happening from multiple recipients: Gmail, Yahoo, .me, etc.

Things I've tried:

Test emails without the attachment (they go through)

Test emails with a different PDF attachment that I sent yesterday (they don't go through)

Test emails with different text in the subject and message body, and with the attachment (they don't go through)

Test emails with the file as a .fdx (Final Draft) rather than PDF (they go through)

Test emails as a One Drive link rather than an attachment (they go through)

Renaming the PDF file (it doesn't go through)

So it appears to be a PDF issue. I'm accessing Outlook on my browser using Chrome on a MacBook Pro. For work purposes I need to be able to send PDF documents as attachments, so I'm hoping to get this figured out soon. I work in a television writer's room so 7 million viewers are depending on me!

Thanks so much for any advice!

    I had this same issue, it appears to be an issue with the updated version of Microsoft outlook. I reverted back to the old version and the issue doesn't appear to happen now. Hope this helps!

    How do you go back to the old version of Outlook?

    Here are some workarounds:

    • Put your PDF into a ZIP file and send the ZIP file.
    • Send a link to a shared folder such as OneDrive or Google drive.
    • Roll back to the older Windows Mail client by uninstalling and reinstalling Windows Mail. (via add or remove programs)
    • Compose the email on your computer and save it in your drafts folder.  Then log in with your phone, find the draft item in your drafts folder and press Send from your phone.
    • Download and use the full-blown Microsoft Office Outlook client (assuming you have access from something such as Microsoft 365 family).

    This will probably get resolved in a few days but I’m posting this in hopes that people will find the solutions helpful.
