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!

    If you use One Drive or I think even Google doc's, create a link to the file or folder and insert that into the email instead and it will send. The recipient will then download the file.

    Just hopping on the bandwagon here in case there is strength in numbers. I have been able to send using the temp fix of changing the body of the email to plain text.

    I am having the same issue.

    Can send emails with no PDF attachments just fine.

    But if a PDF is attached i keep getting

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

    I need to be able to send PDF files for work.

    This needs to be resolved ASAP.

    I have Customers and Insurance companies that need these files!

    Microsoft need to resolve this issue ASAP!
