Try changing the following line from:

Code: Select all

mail.BodyFormat = MailFormat.Text

to

Code: Select all

mail.BodyFormat = Mail.MailFormat.HTML ' for HTML formatted email

or

Code: Select all

mail.BodyFormat = Nothing ' for plaintext or just comment out

If the users are selecting the mail format, use a dropdown or radio in your presentation and then in your codebehind use a "select case" or "if.. else.." to handle the condition.
