New outlook can t drag and drop attachments

Dragging and dropping attachments is currently not supported in New Outlook for Windows. If you need to add a file, use Attach, switch to Classic Outlook, or use Outlook on the web.

Start by using Attach in the message draft. If you want the desktop experience instead, switch back to Classic Outlook by turning off the toggle button in the top right corner of the window. You can also open https://outlook.office.com in a browser and attach files there.

Why can’t I drag attachments in New Outlook?

New Outlook for Windows does not support dragging and dropping attachments. Microsoft also describes this as a known limitation in the redesigned Outlook client. If the same task works in Classic Outlook or on the web, use one of those options instead.

Product limit versus broken setup

The first question is whether you are using New Outlook for Windows. If you are, dragging attachments is not a supported path. Use Attach, switch to Classic Outlook, or open Outlook on the web.

1. Open a blank message in New Outlook.
2. Try dragging a known-good file from File Explorer into the draft.
3. If it does not attach, use Attach, switch to Classic Outlook, or use https://outlook.office.com.

Where Classic Outlook differs

Classic Outlook provides the desktop attachment workflow that New Outlook does not. If your mail process depends on dragging files into a draft, switching back to Classic Outlook is the practical desktop option.

1. In New Outlook, use the toggle in the top right corner to switch back to Classic Outlook.
2. Open a new message.
3. Add the file with the attachment workflow you normally use in Classic Outlook.

For a quick check, open the same message in Classic Outlook and use the same file. If that is the workflow you need, stay in Classic Outlook until New Outlook supports it.

If the file comes from File Explorer

File Explorer is a common place to pick files from, but in New Outlook the drag-and-drop action itself is not supported. Use the attachment button instead of trying to drag the file into the draft.

Test one file in a blank draft

The simplest way to add a file is to open a blank message and attach one file from File Explorer.

1. Open File Explorer.
2. Find one local file, such as a PDF or DOCX.
3. Open a blank draft in New Outlook.
4. Use Attach in the message window.
5. Select the file in File Explorer and send the message.

Check the file and update the app

If you still want to rule out a separate app problem, install pending Outlook and Windows updates, then try the attachment again with Attach. You can also try the same file in Classic Outlook or in Outlook on the web.

1. Close the draft.
2. Install pending Outlook and Windows updates.
3. Reopen New Outlook.
4. Use Attach again, or switch to Classic Outlook if you prefer desktop drag-and-drop.

If the source or target is another Outlook message

New Outlook for Windows does not support dragging attachments the way Classic Outlook does. If you need to move content between messages, use the message actions available in the app, switch to Classic Outlook, or use Outlook on the web.

Move one attachment first

If you are trying to reuse a file from a message, open the message and save or attach the file through the available commands instead of dragging it.

1. Open the source message that contains the attachment.
2. Use the available message or attachment commands to work with the file.
3. Add it to a new draft with Attach, Classic Outlook, or Outlook on the web.

Check shared mailbox behavior

Shared mailboxes matter in business workflows, but the drag-and-drop attachment path is still not supported in New Outlook for Windows. Use the shared mailbox draft with Attach, or switch to Classic Outlook or Outlook on the web.

1. Confirm which mailbox owns the source message.
2. Open the destination draft in the target mailbox.
3. Add the file with Attach.
4. If you need desktop drag-and-drop, switch to Classic Outlook.

For example, if a shared mailbox message contains a file you need to forward, attach it again with the available controls rather than trying to drag it into the new draft.

If drag and drop stops at the desktop or another upload window

If you are using a different app or upload window, the destination may have its own file-picker behavior. Use that app’s Attach, Browse, or upload button instead of dragging.

Confirm the exact drop target

Check whether the target is New Outlook, Classic Outlook, Outlook on the web, or another app. If it is New Outlook, drag-and-drop attachments are not supported. If it is another app, use that app’s file picker.

1. Try the same file in a new Outlook draft.
2. Try the file in the other upload window.
3. Use the target app’s file picker if it offers one.
4. If you need Outlook attachment support, use Attach or switch clients.

Use Attach when the target rejects drops

The quickest workaround in New Outlook is the paperclip command in the message window. In Outlook on the web, use the same attachment control in the browser.

1. Open the destination window.
2. Select Attach or Browse.
3. Choose the file from File Explorer.
4. Send the message or finish the upload.

What should you try next?

If you need attachment support today, use the supported path: Attach, Classic Outlook, or Outlook on the web. If you want to keep using New Outlook, send feedback about the missing drag-and-drop behavior.

Restart Outlook or Windows

Restarting Outlook or Windows can clear temporary sync issues, but it does not add drag-and-drop attachment support to New Outlook.

1. Close Outlook.
2. Restart Windows.
3. Open New Outlook again.
4. Use Attach or switch to another Outlook client.

Switch to a working client

If your work depends on dragging files, use Classic Outlook. If you prefer the browser, open https://outlook.office.com and attach files there.

1. In New Outlook, use the top-right toggle to switch back to Classic Outlook.
2. If you prefer browser access, open https://outlook.office.com.
3. Use the Attach command in the message window.

Capture details before escalation

If you want to request the feature, go to Microsoft 365 Feedback Hub > Send Feedback> Describe your proposal in detail. Include the Outlook version, the exact action you wanted to do, and that you need drag-and-drop attachment support in New Outlook for Windows.

1. Open Outlook’s About or version page and note the build.
2. Write the exact action you tried, such as dragging a file into a draft.
3. State that the path is needed in New Outlook for Windows.
4. Submit the request in Microsoft 365 Feedback Hub.

Keep Classic Outlook available if you rely on drag-and-drop attachment behavior.
