Ensure that the recipient’s email address is valid and free of any typos. Double-check the spelling and domain name to avoid any mistakes that could lead to undeliverable emails.

Ensure that your internet connection is stable and that your Outlook is not in offline mode, which can prevent emails from being sent or received.

5. Remove Junk And Filter Settings

Regularly check your junk folder and filter settings to ensure that legitimate emails are not being labeled as spam or moved to other tabs, causing undeliverable messages.

6. Verify Sender Reputation

Maintain a good sender reputation by avoiding spammy content, maintaining a clean email list, and observing a reasonable time frame between consecutive emails to improve email deliverability.

7. Configure Smtp Server

Double-check the configuration of your SMTP server in Outlook to ensure it is set up correctly, especially if webmail works fine but not Outlook.
