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 am having the same issue since this morning. Any email with a PDF attachment doesn't go through.

    Tried sending it as a forwarded message form my phone and it goes through.

    Microsoft Team please help resolve the issue!

    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!

    Thank you, Kim Craig1!

    I was using the New Design Outlook (which is a separat app from the original) and had these issues also online which looked like the new design.

    Reverting back to the original (non-beta) Outlook App on my computer allowed me to send out the emails with PDF attached.

    Hope MS solves the issue soon, but this shows once again not to use beta versions in a productive environment.

    Thanks,

    Halid
