Solution 1: Patient's email address is invalid. Send a test email to yourself to verify the message is only when using the patient's email address.
Solution 2: If sending from a new email address, check your inbox and open another email. This may activate the email address. Send another test to check.
Error: The operation has timed out.
Solution: Do some research and find out what port your email provider recommends, then try it. For example, for Gmail smtp.gmail.com with SSL, port 465 has worked for sending emails with attachments.
Error: All confirmation emails failed.
Solution: This can happen if the subject line of the email mistakenly includes the body of the message. Check Setup Recall to make sure the subject line has a reasonable amount of words.

Error: Error retrieving email messages: The handshake failed due to an unexpected packet format.
Solution: This error can happen if your email address is not configured properly. Specifically, if your email account uses SSL and you do not have the SSL option enabled, or if you have SSL enabled and your email account does not use SSL. See Email Setup.
Problem: In the Email Inbox or Progress Notes, email preview and message is showing in HTML code.
Solution: This means the email was sent using Rich Text/HTML format instead of Plain Text.
Problem: An incoming encrypted message is not decrypted.
Solution: This happens when decryption fails. Usually decryption happens automatically when the message is received. However, if the email is from an address with a security certificate that is not trusted, your private decryption key is not installed on the local computer, or the encryption is not in the correct format, decryption fails. To see encrypted email options, see Email Encryption Options. To add a certificate to your trusted list or retry decryption. see Email Client, When Decryption Fails.

Solution: Yahoo is blocking "less secure" 3rd-party applications. Create an App password for use with Open Dental.
