Mail Merge

As of May 2026, fully-featured mail merge is only available through the Classic version of Outlook. Below are instructions on how to switch back to Classic Outlook in order to perform a mail merge. For updates on when standard mail merge features will be available in New and Web Outlooks, see this Microsoft roadmap. 

Note: If you attempt to perform a mail merge with New Outlook, you will not receive an error, but messages will not send. Once you open Classic, they will automatically start sending.

  1. Text says "New Outlook" showing it is toggled on.

    First, check New Outlook for a toggle in the upper righthand corner. This allows you to switch back to Classic Outlook. Microsoft may prompt you for feedback; feel free to provide it or skip if you’d prefer.

  2. If you do not have the New Outlook toggle, search your Start/Apps menu for “Outlook (Classic)”  

     

  3. Start menu showing a red X next to "Outlook" and a green check next to "Outlook (classic)".

    Once Outlook Classic has launched, make sure that new Outlook is closed, then open your document and proceed through the mail merge steps as you normally would.

To conduct a mail merge from a shared mailbox, see these instructions.
