Microsoft has revised its email notification process to promptly inform customers about any disapprovals in their ads, keywords, or product offers, with enhancements including a more frequent alert schedule.
The notifications provide details on any rejections within the last 24 hours, including technical errors affecting product ad offers.
To review disapproved content, you can click a hyperlink in the email, directing you to the relevant section in the Microsoft Advertising online interface.
