Unexpected Folder Losses in SharePoint: An Enigma Reveals

Unraveling the Mystery Behind Sudden SharePoint Folder Deletions

Users of SharePoint, especially those with administrative capabilities, have been receiving worrisome messages regarding the loss of a large number of files and folders from their sites. This has been a confusing problem for them in recent weeks. Confusion and worry have been sown by these alerts, which imply the removal of information in bulk that the users are positive they did not start. Despite careful inspections, there is no proof of user-performed deletions or transfers, and the Microsoft 365 access and audit logs provide no indication of any illegal access or activities that may account for the phenomena.

The lack of retention policies that might be automatically initiating these deletions exacerbates the situation. The inexplicable deletions have not yet been stopped despite attempts to fix the problem with Microsoft assistance and by unplugging devices from SharePoint synchronization. The search for a cause—and a solution—continues despite the likelihood that antivirus software is not the problem and the lack of reports of similar instances by other users in similar circumstances. This presents a serious problem for IT administrators and support in determining and addressing the underlying cause of these unauthorized deletions, underscoring the necessity of a more thorough examination of SharePoint's complex internal workings.

Investigating Solutions for Automated SharePoint Monitoring

The offered frontend HTML/JavaScript code and the backend PowerShell script are components of a conceptual solution meant to monitor and notify administrative users of unforeseen deletion occurrences in SharePoint Online. An essential part of backend operations is the PowerShell script. Using the 'Connect-PnPOnline' command, it first establishes a connection to SharePoint Online, which is necessary for any tasks requiring programmatic interaction with SharePoint Online services. In order to ensure that the script executes using the credentials of an authorized user, this command employs the '-UseWebLogin' argument for authentication and requires the URL of the SharePoint site you want to connect to. The script then uses the 'Get-PnPAuditLog' command to get audit log entries within a given date range once the connection has been made. This is especially crucial for monitoring actions like deleting files or folders, which may be signs of unwanted automated activities or unauthorized access.

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 '<script>' tag is designed to interact with the backend, potentially fetching and displaying log information within the designated 'logContainer' div. This enables administrators to have a real-time view of the SharePoint site's health and security, making it easier to respond to potential issues. The combination of these scripts provides a comprehensive monitoring solution, leveraging PowerShell for data retrieval and processing, and HTML/JavaScript for user-friendly display and interaction.

# Connect to SharePoint Online
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com" -UseWebLogin
# Specify the site and list to monitor
$siteURL = "https://yourtenant.sharepoint.com/sites/yoursite"
$listName = "Documents"
# Retrieve audit log entries for deletions
$deletionEvents = Get-PnPAuditLog -StartDate (Get-Date).AddDays(-7) -EndDate (Get-Date) | Where-Object {$_.Event -eq "Delete" -and $_.Item -like "*$listName*"}
# Check if there are any deletion events
if ($deletionEvents.Count -gt 0) {
    # Send an email alert or log the event
    # This is a placeholder for the action you'd like to take
    Write-Output "Deletion events detected in the last week for $listName."
} else {
    Write-Output "No deletion events detected in the last week for $listName."
}

Examining the Automated Deletion anomalies in SharePoint

Maintaining the integrity and security of data inside an organization requires an understanding of the underlying reasons of unexpected file and folder removals in SharePoint. The possible influence of SharePoint's versioning settings and how they can lead to perceived deletions is one element that hasn't been covered yet. Versioning features in SharePoint libraries and lists may cause previous versions of a file or folder to be automatically deleted if the number of versions is limited. One could mistake this for an accidental removal. The workflow and retention regulations outside of the Microsoft administration panel, including those specified in SharePoint's content management settings, are an additional topic to investigate. Inadequately designed retention policies or complex procedures may cause unplanned deletions or archiving activities.

Furthermore, integrating SharePoint with other Office 365 programs may occasionally have unforeseen results. For example, if an automated mechanism links an Outlook email to a SharePoint document library, and that Outlook email is removed, it may also cause the SharePoint document that is linked to be erased. It is essential to comprehend these integrations and their consequences. Furthermore, investigating the function of external programs linked to SharePoint may reveal inadvertent exchanges resulting in removals. Preventing inappropriate deletions requires making sure that all associated programs are properly configured and that their access levels are established.
