How to Use Word Modern Attachments Instead of Traditional Email Insert

When you insert a file into a Word document by using the traditional Insert > Object method, Word embeds a static copy of the file. You cannot update the copy when the original file changes without manually repeating the insertion. Modern Attachments, introduced in Word for Microsoft 365, links the inserted file to its original source in email or cloud storage. This article explains how to enable and use Modern Attachments, the differences from the traditional Insert Object command, and how to avoid common pitfalls.

What Modern Attachments Do and Why They Matter

Modern Attachments is a Word feature that lets you insert a file into a document as a live link rather than an embedded copy. The feature works with files stored in OneDrive, SharePoint, or attached to an Outlook email. When the source file is edited, the attachment in your Word document can update automatically or with a single click.

The traditional Insert Object command embeds the entire file into the Word document. This increases the document file size significantly. It also creates a static copy that does not reflect changes made to the original file. Modern Attachments solve both problems by keeping only a reference to the source file and displaying an icon or preview that links back to it.

Before you can use Modern Attachments, you need Word for Microsoft 365 version 2108 or later. The feature is not available in Word 2019, Word 2021, or earlier perpetual license versions. You also need a stable internet connection if the source file is stored in the cloud.

How to Insert a Modern Attachment in Word

1. Open the source file location
   Navigate to the file you want to attach in File Explorer or your cloud storage folder. The file must be saved in OneDrive, SharePoint, or your local drive.
2. Enable Modern Attachments in Word Options
   Go to File > Options > General. Under the “User Interface” section, check the box labeled “Show Modern Attachments”. Click OK.
3. Place the cursor in your document
   Click the location where you want the attachment icon or preview to appear.
4. Open the Insert tab and click Object
   On the Ribbon, go to Insert > Text > Object. The Object dialog box opens.
5. Choose Create from File and browse for the file
   In the Object dialog box, select the “Create from File” tab. Click Browse, locate the source file, and select it.
6. Check “Link to file” and “Display as icon”
   In the Object dialog box, check the box “Link to file”. Then check “Display as icon”. Click OK. Word inserts an icon that represents the linked file.
7. Test the link
   Right-click the attachment icon and select “Open Linked File”. The source file opens in its default application. Make a small edit and save the source file. Return to your Word document, right-click the icon, and select “Update Link”. The content refreshes.

Inserting a Modern Attachment from Outlook Email

1. Open the email that contains the file
   In Outlook, open the email with the attachment you want to insert.
2. Drag the attachment to the Word document
   Click and hold the attachment icon in the email, then drag it to the open Word document. Word inserts it as a Modern Attachment with a live link to the email source.
3. Update the link when the email attachment changes
   If the sender updates the attachment in the same email thread, right-click the icon in Word and select “Update Link”. Word pulls the latest version.

Common Mistakes and Limitations

Modern Attachments option is grayed out in Ribbon

The “Show Modern Attachments” checkbox in File > Options > General is grayed out if your Word version is older than 2108. Update Word to the latest version from File > Account > Update Options > Update Now. If you use a volume license edition of Office, Modern Attachments may not be available at all.

Attachment icon shows a broken link symbol

A broken link icon means Word cannot find the source file. This happens when the file was moved, renamed, or deleted. Right-click the icon and select “Change Source”. Browse to the new location of the file and select it. The link is repaired.

File size does not decrease after converting to Modern Attachment

Modern Attachments do not automatically remove the embedded copy that was inserted before you enabled the feature. To reduce file size, you must delete the old embedded object and re-insert it using the Link to file method. Use File > Info > Check for Issues > Inspect Document to find embedded objects.

Collaborators cannot see the linked file

If you share the Word document with someone who does not have access to the source file location, they will see a broken link. Store the source file in a shared OneDrive or SharePoint folder and grant view or edit permissions to all collaborators. Use the “Change Source” option to point to the shared location.

Item	Traditional Insert Object	Modern Attachments
File storage method	Embedded copy inside the Word file	Link to external source file
File size impact	Increases significantly	Minimal increase (only icon and link metadata)
Auto-update on source change	No	Yes, with Update Link command
Works offline	Yes	Yes, if source file is local
Requires Word version	All versions	Microsoft 365 version 2108 or later
Collaboration with external users	Works because file is embedded	Requires shared source file location

You can now use Modern Attachments to keep your Word documents smaller and always up to date. Start by enabling the feature in File > Options > General. Next time you need to insert a file, use Insert > Object with the Link to file option. For files from email, drag the attachment directly into the document. If you work with teams, store source files in a shared cloud folder so everyone can access the latest version.
