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'.
