New Outlook vs Classic Outlook SharePoint Connect to Outlook: What to Use Instead

If you have used SharePoint document libraries for years, you likely relied on the Connect to Outlook button in Classic Outlook to sync folders offline. In New Outlook for Windows, that button does not exist, and the classic sync method no longer works. This article explains why Microsoft removed the feature, what replaces it in New Outlook, and which alternative methods you should use instead. You will learn the exact steps to stay productive without the old Connect to Outlook command.

Why SharePoint Connect to Outlook No Longer Works in New Outlook

Classic Outlook included a SharePoint integration that allowed users to click Connect to Outlook inside a SharePoint document library. This action created a SharePoint Lists folder in the Outlook navigation pane. Users could then drag emails into that folder to save attachments directly to the library, or browse library files from within Outlook.

New Outlook for Windows is built on a web-based platform. It does not support the same MAPI-based protocol that Classic Outlook used to connect to SharePoint lists and libraries. The entire sync engine in Classic Outlook relied on the SharePoint List Connector, which is not present in New Outlook. Microsoft intentionally removed this feature because it conflicted with the modern sync architecture used by OneDrive and SharePoint.

What Connect to Outlook Actually Did

When you clicked Connect to Outlook in a SharePoint document library, SharePoint generated a special .iqy or .stp file that Outlook imported. This created a linked folder that synced metadata and file names but did not download the actual file contents. You could see the file list, open files from the folder, and save email attachments to the library by dragging them into that folder.

The feature was designed for read-only browsing and quick attachment saving. It was not a full offline sync solution. Many users assumed it synced files for offline access, but it only cached the folder structure and metadata. Actual file contents were still downloaded on demand.

Steps to Replace Connect to Outlook in New Outlook

Because New Outlook does not support the SharePoint List Connector, you must use one of these three methods to achieve the same results.

Method 1: Sync SharePoint Library with OneDrive

This method gives you offline access to files in File Explorer. It does not create a folder inside Outlook, but you can attach files from the synced folder when composing an email.

1. Open the SharePoint document library
   Go to your SharePoint site in a web browser. Navigate to the document library you want to sync.
2. Click the Sync button
   In the command bar at the top of the library, click the Sync button. It shows a cloud icon with an arrow.
3. Confirm the OneDrive sync prompt
   A OneDrive dialog appears asking if you want to sync this library. Click Sync Now. The files begin downloading to your PC.
4. Access files from Outlook
   In New Outlook, click New Email. Click the Attach button. Navigate to the OneDrive folder that contains the synced SharePoint library. Select the file and attach it.

Method 2: Use the Show in Groups Feature in New Outlook

New Outlook can display SharePoint folders in the folder pane as a collapsed group. This does not sync files offline, but it lets you browse the library structure without leaving Outlook.

1. Open New Outlook
   Launch New Outlook for Windows. Make sure you are signed in with your work or school account that has access to the SharePoint site.
2. Go to the folder pane settings
   At the bottom of the left navigation pane, click the three dots (More options). Select View from the menu.
3. Enable Show in Groups
   In the View settings, toggle Show in Groups to On. The folder pane now groups folders by service: Mail, Calendar, Groups, and SharePoint.
4. Expand the SharePoint group
   Click the arrow next to SharePoint to expand the group. You see all SharePoint sites you have visited recently. Click a site to browse its document libraries inside Outlook.

Method 3: Attach SharePoint Files Directly from the Compose Window

This method is the fastest way to attach a file from SharePoint without syncing anything.

1. Start a new email
   In New Outlook, click New Mail.
2. Click the Attach button
   In the ribbon, click Attach. A dropdown menu appears.
3. Select Browse cloud locations
   Choose Browse cloud locations. A file picker opens showing your OneDrive and SharePoint sites.
4. Navigate to the file and attach
   Click SharePoint in the left pane. Select the site, then the document library, then the file. Click Attach. The file is added as a link.

Common Issues After Switching from Connect to Outlook

I cannot drag emails into a SharePoint folder from Outlook

Classic Outlook allowed you to drag an email into a SharePoint Lists folder to save the attachment to the library. New Outlook does not support this action. You must save the attachment to your local drive first, then upload it to SharePoint manually via the web browser or OneDrive sync.

The SharePoint group in New Outlook shows no sites

New Outlook only displays SharePoint sites you have visited recently in your web browser. If no sites appear, open the SharePoint site in Edge or Chrome, browse a document library, and then return to Outlook. The site should appear in the SharePoint group within a few minutes.

OneDrive sync shows an error for the SharePoint library

If OneDrive fails to sync a SharePoint library, the library may exceed the 5000 item limit for sync. Reduce the number of files or folders in the library. Also confirm that your organization allows SharePoint library sync in the OneDrive admin center.

New Outlook vs Classic Outlook for SharePoint Integration

Item	Classic Outlook	New Outlook
Connect to Outlook button	Supported in SharePoint library	Not available
Drag email to SharePoint folder	Works for saving attachments	Not supported
Browse library in folder pane	Shows as a SharePoint Lists folder	Shows in Show in Groups view
Offline file access	Metadata only, not file contents	Requires OneDrive sync for offline files
Attach file from SharePoint	Drag from folder pane or use Insert	Attach > Browse cloud locations

Classic Outlook offered a direct SharePoint folder integration that New Outlook cannot replicate. New Outlook compensates with cloud-only browsing and OneDrive sync. If you need offline file access, OneDrive sync is the only reliable replacement.

You can now choose between OneDrive sync for offline access, Show in Groups for browsing, or direct cloud attachment for one-off file sharing. If you frequently save email attachments to SharePoint, consider using Power Automate to create a flow that automatically saves attachments to a document library. That workflow works in both Outlook versions and does not require the Connect to Outlook button.
