Using classic Outlook for Windows in business environments
I finally found the option to change the default browser for outlook. The option is in Outlook.
Change the default browser for NEW Outlook:
- Open Outlook
- Go to settings by clicking the gear icon in the top right corner
- Click on the General tab
- Click on Links
- Choose Default browser instead of Microsoft Edge
Change the default browser for OLD Outlook:
- Open Outlook
- File
- Options
- Advanced
- File and browser preferences
- Open hyperlinks from Outlook in: Choose Default Browser
- Restart Outlook
Change the default browser for Windows 11:
- Click on the Wi-Fi or Speaker icon by the Clock, then click on the Gear icon to open Windows Settings.
- Once in Settings, go to Apps → Default Apps.
- Find your preferred browser in the list and click on it.
- Click the button 'Set default'.
Turn off Outlook Side bar:
If you do use Edge but only want to turn off the Outlook Side bar that pops up in edge when you click a link in your email, follow these steps:
- Open Edge
- Click ...
- Settings
- Sidebar
- Under App and notification settings, Click Outlook
- Automatically open Outlook email context in the side pane: Toggle Off.
