Product
Microsoft Word

Windows
Scenario
Attempting to share a document directly from the word processor using the 'Send as Attachment' or 'Send to Mail Recipient' feature.
Observed behavior
The feature works with MAPI-compliant clients like Outlook but fails with the default Windows Mail app. Additionally, users sometimes receive an error stating that an older version of Outlook is running.
Before you start

Ensure you have a MAPI-compatible desktop email application installed (such as Microsoft Outlook or Mozilla Thunderbird) and set it as your default email client in Windows settings.

Solution 1Recommended

Send as Attachment Using a MAPI-Compliant Client

Use Word's built-in sharing feature with a compatible desktop email client like Microsoft Outlook.

The built-in 'Send as Attachment' feature relies on the Messaging Application Programming Interface (MAPI). Because the default Windows Mail app does not support MAPI commands, you must use a traditional desktop email client to use this specific shortcut.

1
Open the sharing menu

Open your document in Microsoft Word and click on the 'File' tab in the top-left corner, then select 'Share'.

2
Select the email option

Click on 'Email' from the sharing options provided.

3
Send as attachment

Choose 'Send as Attachment'. This will automatically open a new message window in your default MAPI-compliant email program with the document attached.

Compatibility Note: If you only have the Windows Mail app installed, this feature will not work. You will need to manually open Windows Mail, compose a new message, and attach the saved document.

Frequently Asked Questions

Why doesn't the 'Send to Mail Recipient' button work with Windows Mail?

The 'Send to Mail Recipient' feature relies on MAPI (Messaging Application Programming Interface) to communicate with your email client. The default Windows Mail app is not MAPI-compliant, which means it cannot process these automated attachment commands from Word or File Explorer.

Can I use third-party email clients to send Word attachments directly?

Yes. Third-party email clients like Mozilla Thunderbird are MAPI-compliant and will work with the 'Send as Attachment' feature, provided they are set as your default email application in your Windows system settings.

How do I share a Word document if my email client isn't supported?

If your email client does not support MAPI integrations, you can simply save the Word document to your local hard drive, manually open your email application, compose a new message, and use the 'Attach File' (paperclip) icon to add your document.
