Using New Outlook on Windows for personal email, calendar, and contact management
Dear K_196_1,
Good day!
Thank you for posting to Microsoft Community. We are glad to assist.
As per your mentioned description about "Default "From" email from shared mailbox" After thorough research and testing I found that you are definitely right this particular setting only exists in the classic Outlook and is not yet available in New Outlook for Windows at this moment. Kindly note that The New Outlook is in a Preview state, and they are still working on the platform/foundation of the application itself. At this stage of the development, luckily restarting the client is very quick. As an alternative, you can switch back to "Classic" Outlook by turning New Outlook Off and If for some reason you don’t see a toggle in the new Outlook for Windows, kindly refer to Toggling out of the new Outlook for Windows preview - Microsoft Support
However, thank you so much for bringing this to our attention, your suggestion is very helpful, and I believe it could make the use of New Outlook even better. Since New Outlook for Windows is still in active development, we will surely raise your concerns to our Product Development Team and hopefully this can be included in the future updates. In the meantime, I did find similar request in the feedback forum New Outlook original email is not included in the replied email when reply to email of shared mailbox · Community (microsoft.com), I have asked my team to vote, and you may upvote for this if it is in line with your requirement. Otherwise, you may as well provide feedback on this feature in your outlook (Help--> Feedback) or by creating a new post in the Feedback Portal via Outlook · Community (microsoft.com) our Product Development Team are committed to enhancing the customer experience by continually examining suggestions to include in the design and development of future product upgrades based on your suggestions.
