SharePoint Network Drive Mapping

Why Map SharePoint as a Network Drive?

Users have been accessing files through network drives for 30 years. When organizations migrate file servers to SharePoint Online, the most common user request is: "Can I still see my files in File Explorer with a drive letter?" The answer is yes — but the method you choose has massive implications for performance, reliability, security, and supportability.

The traditional approach — mapping SharePoint as a WebDAV network drive with a letter like Z: — technically works but creates a fragile, slow connection that disconnects after idle periods, fails with large files, and bypasses modern security controls. It is the approach that generates the most helpdesk tickets in any SharePoint migration. The modern approach — OneDrive sync — provides a far superior experience but requires users to abandon the drive letter mental model and navigate to their organization folder in File Explorer instead.

This guide covers all three methods for accessing SharePoint files from File Explorer — OneDrive sync, WebDAV mapped drives, and Azure Files — with honest assessments of when each is appropriate, how to deploy at enterprise scale via GPO and Intune, how to troubleshoot the most common errors, and the performance and security implications of each approach.

EPC Group has migrated over 500 organizations from traditional file servers to SharePoint Online, and the file access strategy is consistently the factor that determines whether users love or hate the migration. Get this right and the migration succeeds. Get it wrong and users revolt, create shadow IT workarounds, and the migration is perceived as a failure regardless of how well the data was moved.

GPO Deployment: OneDrive Sync for SharePoint

Group Policy is the standard deployment method for Active Directory-joined Windows devices. The following GPO settings configure OneDrive to automatically sync SharePoint libraries without any user interaction — users log into their PC and their SharePoint files appear in File Explorer immediately.

When to Use Each Method: Decision Guide

The correct file access method depends on three factors: whether the user needs offline access, whether a legacy application requires a drive letter path, and whether the organization prioritizes security or backward compatibility. Here is the decision framework EPC Group uses for every SharePoint migration.
