How to Fix Outlook Web App Flickering on a Mac
Question details
The user needs to resolve an issue where the Outlook on the web interface flickers continuously while being used on a Mac.
- Product
- Outlook Web App
- Device & OS
- Mac
- Scenario
- Accessing emails and calendar via Outlook on the web using a Mac web browser.

Verify whether you are logging into a personal Microsoft account or a work/school account, as the administrative troubleshooting steps and support channels will differ.
Troubleshoot Browser Cache and Extensions
Clear your browser data and disable extensions to eliminate conflicts causing the Outlook Web App to flicker.
Flickering is frequently caused by corrupted temporary web files, outdated browser caches, or third-party extensions interfering with how Outlook renders on your Mac.
Open your Mac browser's settings (such as Safari, Chrome, or Edge) and clear your browsing data. Ensure that you specifically check the options to remove cached images and cookies.
Open a new Private Window in Safari or an Incognito Window in Chrome. Log in to your Outlook Web App. If the flickering stops, an active browser extension is likely causing the issue.
If the issue persists, switch to a different officially supported web browser, such as Microsoft Edge for Mac or Mozilla Firefox, to see if it is a browser-specific glitch.
Escalate to Microsoft Support
If local browser troubleshooting fails, escalate the issue based on your Microsoft account type.

Frequently Asked Questions
Why does the Outlook Web App flicker specifically on my Mac?
Screen flickering in web applications on a Mac is typically caused by hardware acceleration conflicts within the browser, corrupted cached data, or incompatible third-party extensions interfering with the webpage's rendering.
Which browsers are best supported for Outlook on the web?
For optimal performance on a Mac, Microsoft recommends using the latest versions of Microsoft Edge, Apple Safari, Google Chrome, or Mozilla Firefox.
