Fix Word Mail Merge INCLUDETEXT Fields Failing After Office Update
Question details
Users need to resolve an issue where Word Mail Merge documents utilizing INCLUDETEXT fields show security warnings and fail to process after an Office update.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Executing a mail merge operation using documents that contain chained INCLUDETEXT fields linked to read-only templates.
- Observed behavior
- The INCLUDETEXT fields fail to pull in the linked documents and display security warnings, despite the linked files residing in trusted network or local locations.
Ensure you have file management permissions to modify the properties of your linked Word templates, and check your current Microsoft Office version number (specifically if it is version 2207 or newer).
Make Linked Templates Writable
Changing the read-only status of your linked Word templates to writable can bypass the newly introduced security blocks and allow INCLUDETEXT fields to process correctly.
Testing indicates that the failure primarily triggers when linked Word templates are set to read-only, especially when those templates contain chained INCLUDETEXT fields. Making these files writable acts as an immediate workaround.
Open File Explorer and navigate to the folder containing your linked Word templates.
Right-click the template file and select 'Properties' from the context menu.
Under the General tab, uncheck the 'Read-only' attribute box, click 'Apply', and then click 'OK'. Repeat this for all templates in the chain.
Roll Back to a Previous Office Version
Since the issue was introduced after Office version 2207, reverting your Microsoft Office installation to an earlier build restores the mail merge functionality.
Escalate to Microsoft Support
If making templates writable is not viable for your multi-client environment, the bug should be escalated to Microsoft Support for a permanent patch.
Try WPS Office for Seamless Mail Merge Processing
If recent Microsoft Office updates have broken your automated mail merge workflows with INCLUDETEXT fields, consider switching to WPS Office.

- 3. Execute Mail Merge: Navigate to the Mailings tab in WPS Writer to manage your merge fields and complete the mail merge process seamlessly.
Frequently Asked Questions
What causes the INCLUDETEXT failure in recent Office updates?
The failure is primarily triggered by security changes introduced in Office version 2207 and later when dealing with chained INCLUDETEXT fields that are linked to read-only templates.
Do Trusted Locations bypass this INCLUDETEXT error?
No, user testing indicates that the error and security warnings persist even when the linked files and templates are placed in designated Microsoft Office Trusted Locations.
Is the macro-blocking update in Office 2209 responsible for this?
No, testing and documentation indicate that the macro-blocking changes introduced in version 2209 are likely unrelated to this specific INCLUDETEXT field failure.
Can I keep my templates read-only for multiple clients while fixing this?
If the templates must remain read-only to support multiple clients safely, the current writable-file workaround will not suffice. You will need to roll back to an earlier Office version (like 2206) or escalate the bug to Microsoft Support.
