Set Outlook as the Default Mail Client

Word requires Microsoft Outlook to be the system's default email reader to enable the email merge functionality.

On macOS, the default email application is often set to Apple Mail. If Outlook is not recognized as the default client, Word will disable the final merge-to-email step.

1
Open Apple Mail

Launch the Apple Mail application on your Mac, even if you do not actively use it.

2
Access Mail Settings

Click on 'Mail' in the top menu bar and select 'Settings' (or 'Preferences' on older macOS versions).

3
Change Default Email Reader

In the General tab, look for the 'Default email reader' dropdown menu and change it from Mail to Microsoft Outlook.

4
Restart Your Mac

Close the settings, restart your Mac to apply the system changes, and then reopen your mail merge document in Word.

Set Outlook as the Default Mail Client
System Preference Applied: Once Outlook is set as the default, Word will be able to communicate with it to process the email dispatch.

Frequently Asked Questions

Why is the Finish and Merge button greyed out in Word for Mac?

This usually happens because a recipient list has not been successfully connected to the main document, or because Microsoft Outlook is not set as your Mac's default email reader.

Can I use Apple Mail for a Word email mail merge?

No. When merging to email in Microsoft Word for Mac, the software specifically requires Microsoft Outlook to process and send the messages. It does not support Apple Mail.

What data source formats does Word for Mac support for mail merge?

Word for Mac supports Excel workbooks (.xlsx), Comma Separated Values files (.csv), text files (.txt), FileMaker Pro databases, and your Apple Contacts list.

Does my main mail-merge document need to be open to finish the merge?

Yes. The 'Finish & Merge' command is only available when you are actively viewing the main mail-merge document that contains your merge fields.
