Hi questioner
Thanks for reaching out to the Microsoft Q&A forum.
Based on the information you described, it looks like you received an error message saying "application not found" when you tried to open links in your email.
The "Application not found" error when clicking a link in Outlook usually means Windows doesn’t know which browser to use. This often happens if your default browser settings are missing or incorrect. Here are some recommend solutions you can try:
1/ Re-select Your Default Web Browser (Even if a browser is already set)
- Go to Settings > Apps > Default apps > Scroll to Web browser > Click it and re-select your preferred browser
2/ Check file type settings:
- Go to Settings > Apps > Default apps > Scroll down and click Choose default apps by file type and make sure .html and .htm are set to open with your browser.
If the issue continues, I’ll need a bit more info to help troubleshoot:
-The issue occurs in both the Outlook desktop client and the Outlook Web App (OWA)?
-What version of Outlook are you using? (New Outlook or Outlook Classic)
-Are you using personal account or business account?
-If possible, please share a screenshot or full error message so I can better understand the issue. Kindly blur or hide any sensitive information in the image.
I am looking forward to your response.
