How to Mail Merge in Microsoft 365 Without Using Word
Question details
The user wants to know if they can perform a mail merge directly using Outlook .msg or .oft files without relying on Microsoft Word.

- Product
- Microsoft 365 Outlook
- Device & OS
- not provided
- Scenario
- Attempting to send personalized mass emails to Outlook contacts using only Outlook message files or templates.
- Observed behavior
- Microsoft Outlook cannot independently perform a mail merge because the necessary mail-merge engine is housed entirely within Microsoft Word.
Determine whether your mass email requires personalized data fields (like names or company titles) or if a standard, identical message to all recipients will suffice.
Use Microsoft Word to Execute the Mail Merge
Since Outlook lacks a built-in mail merge engine, you must use Microsoft Word to process personalized fields while relying on Outlook strictly for message delivery.
Microsoft designed the Office suite so that Word acts as the engine for mail merges. Even if you only want to send an email, Word is required to map the contact data to the message placeholders.
Open Microsoft Word, navigate to the 'Mailings' tab, and click 'Start Mail Merge'. Select 'Email Messages' from the dropdown menu.
Click 'Select Recipients' and choose 'Choose from Outlook Contacts'. Select the appropriate contact folder containing your target audience.
Write your email content in the Word document. Use 'Insert Merge Field' to add personalized tags like First Name or Company.
Click 'Finish & Merge', then select 'Send Email Messages'. Enter your subject line and click 'OK' to route the emails through Outlook.

Use an Outlook Template and Contact Group for Non-Personalized Messages
If you do not need personalized data fields for each recipient, you can bypass Word entirely by sending a saved Outlook template to a predefined Contact Group.

Frequently Asked Questions
Can I use Excel to do a mail merge directly through Outlook?
No. While Excel is excellent for storing your contact list and acting as the data source, it does not have a mail-merge engine. You still need to route the Excel data through Microsoft Word to format the fields and send the messages via Outlook.
Why can't I use an .oft file for a traditional mail merge?
Outlook Template (.oft) files are designed to save static email layouts. They lack the underlying data-processing capabilities required to automatically swap placeholder fields with individual contact data dynamically.
How do I hide recipients' addresses when sending a template to a contact group?
When addressing your email template to a contact group in Outlook, place the group name in the 'Bcc' (Blind Carbon Copy) field rather than the 'To' field. This ensures individual email addresses remain private and prevents recipients from replying to everyone.
