Using older versions of Outlook for Mac in business environments
Thank you for sharing your concerns.
I truly understand how this issue is impacting your current workflow. At the moment, Microsoft has not released any further updates or a new version to fix this issue yet. I will continue to monitor the situation and keep you informed of any new information as they become available.
Additionally, if you prefer not to use the New Outlook for Mac as a workaround, another option you may consider is reverting to a previous legacy version of Outlook. Based on my research, a rollback to an earlier version, such as 16.108 or 16.109.3, has helped resolve similar issues in some cases. You may try the following steps to see if the issue persists:
Open any Office app > Help > Check for Updates > uncheck “Automatically keep Microsoft Apps up to date.”.
Quit all Office applications.
Then, go to Applications > select Microsoft Outlook > move it to Trash.
Install version 16.108, 16.109, or 16.109.3 from the following link: Update history for Office for Mac - Office release notes | Microsoft Learn
