Hi,
Set the email settings first, go to Options/Preferences(for Mac OS) → Other/Email menus → Email Settings →
Select the radio button labeled "Use SMTP to send email directly to the mail server."
For SMTP mail host, enter the server address. This varies depending on your email client, for instance:
Gmail accounts use > smtp.gmail.com
Yahoo accounts > smtp.mail.yahoo.com
Hotmail/MSN/Outlook.com > smtp.live.com
AOL > smtp.aol.com
Comcast > smtp.comcast.net
Other: Contact your mail provider for your SMTP server address
Check the box labeled "Server requires authentication" and enter your username (e.g., youraddress@gmail.com) and your password.
Check the box labeled "Use secure connection (SSL/TLS) if available." (Comcast users should skip this step)
Enter your email address into the field labeled "Default reply email."
Click OK to save your changes, the window should close without no errors.
Click OK to save your changes and close the options menu.
If you want to use an email client program(like Outlook or Eudora) to send your transcriptions, from the Express Invoice Email Settings menu, select "Use MAPI to send email..." instead of "Use SMTP to send email..."
