How to Open and Access Outlook in Safe Mode in Mac? – [Solved 2025]
Are you experiencing issues when trying to open Outlook on your Mac? Wondering if launching Outlook in Safe Mode could help resolve the problem? You’re not alone—these types of technical glitches are common among Mac users. Fortunately, there are ways to troubleshoot and restore Outlook to its normal functioning.
In this blog, we’ll walk you through the concept of Safe Mode in Outlook, explain how it differs on macOS, and provide step-by-step alternatives that can help you resolve Outlook-related issues effectively.
What Is Safe Mode in Outlook?
On Windows, Outlook Safe Mode is a special launch state that disables all custom settings and add-ins, allowing users to identify and fix problems caused by third-party extensions or corrupted configurations.
However, on macOS, Safe Mode for Outlook does not exist as a built-in feature. Microsoft Outlook for Mac does not support launching in Safe Mode in the traditional sense. That said, you can still achieve similar results by manually disabling add-ins, resetting preferences, or creating a new user profile.
Steps to Troubleshoot Outlook on Mac (Safe Mode Alternatives)
Unlike Outlook for Windows, Outlook for Mac does not support launching in Safe Mode using commands like Outlook.exe /safe. However, there are several manual troubleshooting steps you can perform to achieve similar results. These helps resolve issues caused by add-ins, corrupted preferences, or profile errors.
