After upgrading Outlook to v16.103.2 on my Mac with OS Tahoe 26.1, I found that all mailers we designed using legacy Outlook are breaking, and the design got distorted. I could not find an option to revert to the legacy app. Can you please help me get the legacy app back on my system?

    Hi @Sailendra

    Thank you for posting your question in the Microsoft Q&A forum.

    May I ask which license are you using?

    Please note that some licenses don't support Legacy Outlook especially Outlook downloaded from App Store.

    If you have an eligible license that supports Legacy Outlook, please download it directly from Microsoft web. Update history for Office for Mac - Office release notes | Microsoft Learn

    Additionally, if you don't meet this issue from the previous version, you can consider rolling back to the older version. My recommendation is version 16.102.x

    And remember to turn off Auto update by going to Help> Check for Updates. In the Microsoft AutoUpdate, clear the Automatically keep apps up to date.

    I saw that you also mentioned missing the local folder in the left panel. Make sure "Hide on My Computer" is not checked in Settings > General.

    Please try and let me know if it works for you.
