How to Migrate Exchange Public Folder to SharePoint: A Complete Guide

Public folders in Microsoft Exchange have long served as shared repositories for emails, contacts, calendars, and documents within organizations. But with the rise of cloud collaboration platforms like SharePoint Online, many businesses are now opting to migrate Exchange public folder to SharePoint for improved productivity, security, and scalability.

In this article, we’ll explore why this migration is essential, the benefits it brings, and how to execute it effectively. Whether you’re managing legacy Exchange public folders or transitioning to Microsoft 365, this guide will provide a clear roadmap.

What Are Exchange Public Folders?

A public folder in Exchange allows multiple users to access and share information within a Microsoft Exchange environment. These folders often store:

Shared mailboxes
Department calendars
Task lists
Company-wide contact directories
Archived emails and documents

Despite their usefulness, public folders were designed decades ago and lack the modern capabilities that tools like SharePoint Online offer today.

Why Migrate Public Folders to SharePoint?

The need to migrate public folders to SharePoint stems from a shift toward cloud-based collaboration, especially with Microsoft 365 becoming the norm. Here’s why organizations are moving away from Exchange public folders:

1. Enhanced Collaboration

Unlike Exchange public folders, SharePoint enables real-time co-authoring, commenting, version control, and file sharing, streamlining teamwork and increasing productivity.

2. Centralized Document Management

SharePoint allows structured document libraries with metadata, permissions, and workflows—perfect for departments that need organized access to shared content.

3. Better Security and Access Control

SharePoint offers granular permissions at the file, folder, and library levels. This ensures users only see the content relevant to them, unlike public folders, which often grant broader access.

4. Cloud Accessibility

SharePoint Online is accessible from anywhere, anytime. There’s no need for VPNs or Outlook-based access as required with on-premises Exchange public folders.

5. Scalability and Integration

SharePoint integrates seamlessly with Microsoft Teams, OneDrive, Power Automate, and more. As your business grows, SharePoint adapts—public folders do not.

Common Use Cases for Migration

Organizations choose to migrate Exchange public folders to SharePoint in scenarios such as:

Microsoft 365 adoption: Migrating legacy on-premise data to the cloud.
Departmental collaboration: Moving shared calendars, emails, and docs to team sites.
Email archive migration: Transferring email conversations and attachments into document libraries.
Compliance: Leveraging SharePoint’s retention policies and audit trails for governance.

Pre-Migration Considerations

Before beginning the migration, consider the following:

1. Audit Existing Public Folders

Understand what’s inside your public folders:

Type of content: documents, calendars, mail items
Folder size and structure
User permissions

2. Decide on Target Locations in SharePoint

For each public folder, decide:

Should it become a document library?
Does it fit better in a SharePoint Team Site or Communication Site?
Who needs access to it?

3. Clean Up Old Content

Archive or delete outdated content to minimize clutter and improve migration speed.

Migration Methods

There are several ways to migrate public folders to SharePoint, but the method you choose depends on your technical expertise, content size, and business needs.

Manual Migration (Not Recommended for Large Migrations)

Export emails or files from public folders using Outlook.
Upload them into SharePoint document libraries.
Pros: No cost.
Cons: Time-consuming, error-prone, loses metadata, and no support for complex data types.

Using PowerShell Scripts

PowerShell can help export data from Exchange and import it into SharePoint via CSV or other connectors.
Pros: More control over the process.
Cons: Requires scripting skills, no UI, minimal error handling.

Benefits include:

Best Practices for a Smooth Migration

Here are some key tips for a successful migration:

Pilot the Migration

Test a small set of public folders to identify potential issues before full migration.

Maintain Folder Hierarchy

Choose tools or strategies that replicate the folder structure in SharePoint to avoid user confusion.

Map Permissions Carefully

Make sure SharePoint permissions reflect the same access levels users had in Exchange.

Communicate with Stakeholders

Inform employees about the migration timeline, new SharePoint structure, and how they can access the migrated content.

Post-Migration Validation

Verify that the content has migrated correctly. Check for:

Missing files
Permission mismatches
Broken links or metadata loss
