How do you send an email via mail merge from an alias (shared) account NOT your individual email account?

Hi Kristen Palazzola

Thank you for posting your question in Microsoft Q&A regarding sending mail merge emails from an alias or shared mailbox using Microsoft Word.

Based on your description and my research, Microsoft Word’s built-in Mail Merge feature currently does not allow to select a different “From” address. By default, it sends emails through your primary Outlook account. You can change your default mailbox in Outlook. If you want all mail merge emails to come from a specific sender, you can temporarily set that mailbox as your default account in Outlook.

• Go to File > Account Settings > Account Settings > Email tab.
• Select the mailbox you want and click Set as Default.
• Restart Outlook before running the mail merge. This ensures Word uses that account when sending emails.

If you need to use the Secure Mail Merge Add-in to specify the sender address when performing a mail merge. First, please ensure the alias/shared mailbox is added to your Outlook profile and you have Send As or Send on Behalf permissions. For guidance, you can refer to: Installing the SecureMailMerge Add-In for Outlook
