I am using "sp_send_dbmail" to send emails with SQL server. Problem is that as soon as the email subject contains a special character such as an "ä", sending the email fails.
I get the following error in the log file: "Exception Message: Cannot send mails to mail server. (The specified string is not in the form required for a subject.)
Having such special characters in the body works though.
Many thanks for your help here,
