Using Outlook Express when writing or answering e-mails I have gone to the Tools and there is no choice for altering the size or anything else to produce the e-mail I require.
Emails can be sent and received in 2 formats - plain text and rich text (HTML).
If your email system is set up to send and receive in plain text then you get NO formatting options.
If it is set a Rich Text (HTML) then you can create formatting.
Use the options in your email system to switch between plain text and rich text.
Note, if you CREATE an email in rich text, but the person who gets it has their systyem set up to receive plain text only then they will not see ANY of the formatting.
Eureka ! I hope I have found some form of solution.
