You have a Microsoft 365 E5 subscription that uses Microsoft Defender for Office 365 and contains a user named User1.
User emails a product catalog in the PDF format to 300 vendors. Only 200 vendors receive the email message, and User1 is blocked from sending email until the next day.
You need to prevent this issue from reoccurring.
What should you configure?
