Hi @Carlson, Sonya,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and sharing your concern regarding classic Outlook opens even after pinning and opening new Outlook. Based on your description, the behavior typically occurs when Windows is still launching Classic Outlook instead of the New Outlook for Windows, even though the new version has been installed and pinned.
This can happen if the pinned taskbar shortcut is pointing to Classic Outlook, the default file associations are still assigned to Classic Outlook or an organizational policy is enforcing the Classic version.
Please follow the steps below to ensure the New Outlook is properly pinned and set as default:
- Pin the New Outlook Correctly
- Click Start.
- Type "Outlook" or Outlook (new).
- Right-click and select "Pin to taskbar".
- Remove any existing Outlook icon from the taskbar to prevent launching the Classic version.
After completing this, close all Outlook windows and reopen Outlook using only the newly pinned icon to confirm it opens the New version.
- Set New Outlook as the Default App
- Open Settings.
- Go to Apps > Default apps.
- Search for "Outlook" or Outlook (new).
- Select it and assign it as default for relevant file types and protocols such as:
- MAILTO
- .eml
- Other Outlook-related associations
This ensures email links and Outlook files open in the New version instead of Classic.
- Contact IT admin
If the issue continues after completing these steps, it may be related to Group Policies or administrative configurations applied by your IT department. I recommend contacting your IT administrator to confirm whether any policies are enforcing Classic Outlook.
If needed, they can also create a support ticket on your behalf to investigate further.
