How to Prevent Mail Merge from Inserting Mailto Text in Word
Product
Microsoft Word, Microsoft Access
Device & OS
not provided
Scenario
Performing a mail merge in a Word document using an Access database as the primary data source.
Observed behavior
Email fields format incorrectly in the merged document, displaying a 'mailto:' prefix or underlying hyperlink value instead of a clean, plain-text email address.
Before you start

Before making structural modifications to your database tables, ensure you create a complete backup of the Access file to prevent accidental data loss in the event of corruption.

Solution 1Recommended

Change the Access Email Field Type to Short Text

Modifying the field type in your Access database from Hyperlink to Short Text removes the underlying mailto properties, ensuring a clean plain-text merge in Word.

When Microsoft Access stores an email address as a Hyperlink, it includes hidden hyperlink properties like 'mailto:'. Converting the field to Short Text strips these extra attributes, leaving only the plain email address for your Word mail merge. Because database structure changes can sometimes cause issues in large databases, ensure you have backed up the file before proceeding.

1
Open your Access database in Design View

Launch Microsoft Access, open your database, and locate the table containing the email addresses in the navigation pane. Right-click the table and select 'Design View'.

2
Locate the email field

Find the row containing your email address field. Click on the drop-down menu in the 'Data Type' column next to it.

3
Change data type to Short Text

Select 'Short Text' from the Data Type drop-down menu instead of 'Hyperlink'.

4
Save the changes

Click 'Save' on the quick access toolbar. If you receive a warning message stating that data might be lost, confirm the change to proceed.

5
Refresh your Word mail merge

Open your Microsoft Word document, refresh the data source connection, and preview the mail merge results. The email addresses will now appear as plain text without the 'mailto:' prefix.

Change the Access Email Field Type to Short Text
Data Loss Warning: The generic warning about potential data loss is standard when changing data types in Access. As long as your email addresses do not exceed the Short Text character limit, no actual data will be lost.

Frequently Asked Questions

Why does Word show 'mailto:' in my mail merge results?

When Word pulls an email address stored as a Hyperlink in an Access database, it imports the underlying HTML link properties. This includes the 'mailto:' prefix, which is normally hidden and used by web browsers or email clients to trigger new message windows.

Will changing the field type to Short Text delete my emails?

No, changing a Hyperlink field to Short Text in Access strips the clickable link properties but leaves the visible email address text intact. It is always recommended to back up your database first just to be safe.

Can I fix the mailto text directly in Word without touching the database?

While it is best to correct the data source directly to prevent recurring issues, you can sometimes toggle field codes in Word (by pressing Alt+F9) and manually adjust the merge field switches, though converting the Access field to Short Text is a far more reliable solution.
