Using New Outlook on Windows for personal email, calendar, and contact management
Welcome Walt Wojcik,
Thanks for reaching out to Microsoft Q&A Forum. I understand that you cannot open any email attachments in New Outlook for Windows 11.
Do you receive an error message when selecting an attachment? Are you using a personal Outlook.com account or a work or school account?
Please make sure you already tried the Q&A Assist steps. In addition, please try the following:
1, Repair New Outlook.
- Close Outlook.
- Open Settings > Apps > Installed apps.
- Find Outlook (new), select the three dots, and open Advanced options.
- Select Repair, and then test Outlook again.
2, If Repair does not help, return to Advanced options and select Reset.
- Open Outlook and sign in again.
- Test an attachment from a trusted sender.
3, Update Microsoft Edge.
- Open Edge.
- Select Settings and more > Help and feedback > About Microsoft Edge.
- Allow available updates to install, and then restart the computer.
4, Check the default apps for common attachment types.
- Open Settings > Apps > Default apps.
- Search for extensions such as .pdf, .docx, .xlsx, and .jpg.
- Assign an appropriate application to each extension.
5, Install available Windows updates.
- Open Settings > Windows Update.
- Select Check for updates.
- Install the updates and restart the computer.
Looking forward to your update.
