Frequently Asked Questions

Why do only PowerPoint and Outlook crash while Word and Excel work fine?

PowerPoint and Outlook rely on specific background services and shared software libraries that differ slightly from Word and Excel. An incomplete update or a specific macOS compatibility bug can isolate failures to just these two applications while leaving the others intact.

How can I manually download the PowerPoint and Outlook updates?

You can bypass the Microsoft AutoUpdate tool by navigating to the Microsoft 365 Mac release history page on the official Microsoft website. From there, you can download the standalone installer packages specifically for PowerPoint and Outlook.

Will reinstalling Microsoft Office on Mac fix this issue?

Yes, if updating the applications does not work, completely uninstalling Office by moving all Office apps to the Trash and clearing related Library files, followed by reinstalling a fresh copy from your Microsoft account, often resolves stubborn crashes.
