Sending, receiving, and organizing email in Outlook.com
Hello, thank you for reaching out to Microsoft Q&A.
This may be a temporary server issue.
If you’re accessing email in Outlook.com through a web browser, try opening an incognito or private browsing window on Edge and see whether you can find your emails through Outlook Search.
Alternatively, if you have a VPN turned on on your device, temporarily turn it off.
If you’re still having issues, try another web browser such as Chrome or Firefox to see whether that resolves the problem.
If you can access your emails in a private browsing window, try clearing your browser history, cache, and cookies. Sometimes server issues are temporary, you can wait for a while and try again.
Let me know if you still need more help.
