I can receive and send emails to some, but not to others

If you are experiencing issues with sending and receiving emails to some contacts in your Outlook.com account, here are some steps you can take to troubleshoot the problem:

1. Check for Service Issues: Sometimes, the issue may be related to service outages. You can check the Microsoft 365 Service health status to see if there are any ongoing problems that might be affecting email delivery.
2. Verify Email Addresses: Ensure that the email addresses you are trying to send to are correct. A typo in the address can prevent successful delivery.
3. Check Spam/Junk Folder: Sometimes, emails may be incorrectly flagged as spam. Check your spam or junk folder to see if the emails from certain contacts are being filtered there.
4. Review Blocked Senders: Make sure that the email addresses you are having trouble with are not on your blocked senders list. You can manage blocked senders in your Outlook settings.
5. Update Outlook: Ensure that your Outlook client is up to date. Running outdated software can lead to various issues, including email delivery problems.
6. Run Diagnostics: You can use the Microsoft Support and Recovery Assistant to diagnose and fix common Outlook issues. This tool can help identify problems with your account and provide solutions.

If these steps do not resolve the issue, consider reaching out to Microsoft support for further assistance.

Hi George, I understand how confusing that can be when email works for some contacts but not others. This usually happens because of issues like incorrect email addresses, blocked senders, or problems with the recipient’s mail server. Let’s start with a quick check: confirm the addresses you’re sending to are typed correctly and not in your blocked list. Also, try sending from Outlook.com web instead of the app to see if it works there. If you’re getting any error messages or bounce-back emails, can you share what they say? That will help us figure out if it’s a server or account setting issue.
