Unraveling the Mystery Behind Sudden SharePoint Folder Deletions
In recent weeks, a perplexing issue has emerged for SharePoint users, particularly those with administrative rights, who are receiving alarming notifications about the deletion of a significant number of files and folders from their sites. These notifications, which suggest a bulk removal of content that the users are certain they did not initiate, have sown confusion and concern. Despite thorough checks, there's no evidence of manual deletions or moves by the user, nor do the Microsoft 365 access and audit logs indicate any unauthorized access or actions that could explain the phenomenon.
This situation is further complicated by the absence of any retention policies that could be triggering these deletions automatically. Efforts to resolve the issue through Microsoft support and by disconnecting devices from SharePoint synchronization have yet to stop the mysterious deletions. With antivirus software unlikely to be the culprit, and similar incidents not reported by other users under comparable conditions, the quest for a cause—and a solution—continues. This introduces a significant challenge for IT support and administrators in identifying and mitigating the root cause of these unwarranted deletions, highlighting the need for a deeper investigation into SharePoint's intricate workings.

Exploring Automated SharePoint Monitoring Solutions
The backend PowerShell script and the frontend HTML/JavaScript code provided are part of a conceptual solution aimed at monitoring and alerting administrative users about unexpected deletion events in SharePoint Online. The PowerShell script is a crucial component for backend operations. It starts by establishing a connection to SharePoint Online using the 'Connect-PnPOnline' command, which is essential for any operations that need to interact with SharePoint Online resources programmatically. This command requires the URL of the SharePoint site you wish to connect to and uses the '-UseWebLogin' parameter for authentication, ensuring that the script runs under the credentials of an authorized user. Once the connection is established, the script then utilizes the 'Get-PnPAuditLog' command to retrieve audit log entries within a specified date range. This is particularly important for tracking actions such as file or folder deletions that could indicate unauthorized access or unintended automated behaviors.
The audit log entries are filtered using 'Where-Object' to isolate deletion events related to a specified list or library, providing a targeted approach to monitoring. If any deletion events are found, the script can be configured to take an action, such as logging the event or sending an email alert. On the frontend, the HTML and JavaScript code snippet offers a simple interface for displaying these logs or alerts. It structures the webpage with basic HTML tags and includes a script for dynamic content manipulation. The JavaScript within the '
