Outlook for mac keeps crashing on startup

Hi NeilWetherall,

below are some potential options to resolve this issue your having:

1. Ensure Software Updates:
   Confirm that both your macOS and Outlook are up to date. You can update macOS through System Preferences and check for Outlook updates by clicking on the Help menu within the application. After updating, restart your Mac to see if the issue persists.

2. Check for Outlook Updates:
   Open Outlook and navigate to the Help menu to check for updates. If available, download and install the update. Restart your Mac afterward and check if the crashing issue persists.

3. Identify Problematic Emails:
   In some cases, Outlook crashes due to a specific problematic email.
   Try to identify and delete such emails, especially if they are sent to large distribution lists. Another user mentioned success in resolving the issue by pinpointing and removing a problematic email that was otherwise handled fine by Apple Mail.
