Nothing on effect of installing Classic Outlook on computer with Microsoft 365 New Outlook. Will data be lost? Can you still use New Outlook? How to change to Classic when you need Mail Merge with emails? Why can't Microsoft add MAPI to New Outlook?

You can run both the new and the classic Outlook on the same PC. Functionality isn't the same (yet). The new Outlook is still a work in progress. You can send feedback in the portal at https://feedbackportal.microsoft.com/feedback/forum/89a8afa3-2e1c-ec11-b6e7-0022481f8472 .

If you want to discuss Outlook further in Q&A, please start your own thread. Use the Ask a question option. Good luck.

Most of my mail merging is completed through Power Automate, but how can such a routine and commonly used feature in Word not be carried forward? I needed to do a quick mail merge to send customized email to many colleagues, and it took me more time to find why mail merge was not working than it would have to manually type out the 50+ individual emails. I would never have thought this would not have been included when migrating to a seemingly more feature-rich version of Outlook.

Looking at the roadmap presented above for a January 2026 release... still NOT available. This is not rocket science, and it is very inconvenient to maintain two versions of the same program (Outlook)... I sure hope MS has not lost its ability for critical thinking...

I came to this thread again to echo Tim's sentiment. This is such a simple feature that was widely used. My sales team was able to handle mail merge on their own. I do not want to have to make my team stop what they are doing to create a PA automation for a one off email. It is a waste of time and resources.

As you may have seen, the Roadmap now says this is delayed until June.

Hello @Johannes Kingma,

Thank you for reaching out to Microsoft Q&A Forum.

At this time, Mail Merge in Word depends on MAPI integration, which is only available in the classic Outlook for Windows. The New Outlook does not currently support this feature, so when you start a Mail Merge, Word will attempt to open Outlook (classic). This is expected behavior.

We understand this may cause inconvenience, and we truly appreciate your patience as we continue improving the New Outlook experience. If you need to use Mail Merge, please switch back to Outlook (classic): In Outlook, go to Settings and turn off “Try the new Outlook”.

Microsoft is aware of this limitation and may consider adding support in the future, but there is no official timeline yet. Your feedback is valuable as we work to enhance the New Outlook experience.

The best way to ensure this gets prioritized by the product team is to submit feedback through the official Microsoft Feedback Portal. The more votes and comments an item receive, the higher its visibility and priority. Here’s the link: https://feedbackportal.microsoft.com/feedback

If you share the link to your feedback here, others in the community (including myself) can upvote it to help bring more attention to the issue.

I totally understand your intention to keep the thread open and hear from more users who might be facing the same issue. I strongly encourage you to mark an “Accepted Answer” for now. Doing so will pin the thread to the top, making it easier for others to find when searching with related keywords. It also helps highlight the discussion for users who might benefit from it, and of course, the thread remains open for anyone to join and share their thoughts.

Thank you again for your patience and raising this important topic, engaged member of the community.

Warmest Regards.

Helloo @Johannes Kingma,

Thank you for your patience and for confirming that you are switching back to the classic version for now. I wanted to provide a quick update that may ease the inconvenience:

According to the Microsoft 365 Roadmap, a preview version of Mail Merge support in the New Outlook for Windows is currently scheduled to be added in January 2026!

This is a great sign that the feature you need is being actively worked on.

In the meantime, sticking with Outlook (classic) is the correct workaround until that preview version, and eventually the full feature, is available.

We appreciate you being an early adopter and sharing your valuable feedback.

Warmest Regards.

The new Outlook does not fully support all features available in the classic Outlook, including the mail merge functionality that relies on classic Outlook libraries. When you attempt to start a mail merge with the new Outlook open, it may redirect to the classic Outlook to perform this function. Microsoft recommends running both the new Outlook and classic Outlook side-by-side to ensure that features like mail merge continue to work seamlessly until they are fully available in the new Outlook.
