Update macOS and Outlook for Mac
Keeping your operating system and Outlook application fully updated is the most reliable way to resolve low-level framework conflicts causing app crashes.
Software crashes on macOS, specifically those involving CoreFoundation errors, frequently stem from version incompatibilities. Updating both your macOS and the Outlook client ensures you have the latest bug fixes from Apple and Microsoft.
Click the Apple menu in the top-left corner of your screen, select 'System Settings' (or 'System Preferences'), click on 'General', and then choose 'Software Update'. Install any available updates for Ventura.
Open the Microsoft Outlook application. From the top menu bar, click on 'Help' and select 'Check for Updates'. Follow the prompts in the Microsoft AutoUpdate tool to install the latest version.
Once both updates are fully downloaded and installed, restart your Mac and attempt to create a new folder in Outlook to verify if the issue is resolved.

Boot Your Mac in Safe Mode
Safe Mode helps determine whether background software interference or corrupted cache files on your startup disk are responsible for the Outlook crashes.
Contact Dedicated Outlook Support
If standard troubleshooting fails, using the in-app support feature connects you directly to the dedicated Outlook for Mac team for advanced diagnostics.

Frequently Asked Questions
Why does Outlook for Mac crash with an EXC_BAD_INSTRUCTION error?
This specific error generally indicates a low-level software conflict where the application attempts an invalid operation. In Outlook for Mac, this is frequently tied to the CoreFoundation framework when the application version is slightly incompatible with a recent macOS update.
Can a corrupted Outlook profile cause folder creation crashes?
Yes. If your Outlook profile database is corrupted, attempting to modify the folder structure can lead to an immediate crash. Creating a new profile using the Outlook Profile Manager and re-syncing your account can often bypass this issue.
Will reinstalling Outlook fix the folder creation crash?
Reinstalling the application can repair broken program files that might be causing the crash. Ensure you move the current Microsoft Outlook app from your Applications folder to the Trash before downloading a fresh copy from the Mac App Store or the Microsoft website.
Where can I find the crash logs for Outlook on macOS?
You can locate detailed crash reports by opening the 'Console' app on your Mac (found in Applications > Utilities). Select 'Crash Reports' from the left sidebar and look for the most recent entries labeled with 'Microsoft Outlook'.
