What type of email would be classified with an Unanalyzed Attachment reason?

The classification of an email with an Unanalyzed Attachment reason is correctly attributed to emails with attachments larger than 30 MB. In data management and email systems, files that exceed certain size thresholds often encounter restrictions in automated analysis or processing capabilities. This can be due to various factors such as limitations on storage, processing time, or network performance.

When attachments surpass this size limit, they may not be able to undergo standard analysis processes that check for security, relevance, or compliance issues. As a result, these larger attachments are left unanalyzed, leading them to be categorized under the Unanalyzed Attachment reason. This classification serves as a prompt for administrators or users to manually assess the content of these large attachments to ensure they meet necessary policies and regulations.

In contrast, emails without attachments, those with smaller attachments that do not require additional review, or emails that are part of standard threading do not fall under this classification, as they either present no issues with size or are managed through regular protocols.
