The following message appears:unexpected end tag: expected ''font'' ,actual ''b'' what it means what shall i do?

Assuming you are using Outlook, click on Tools > Options > Stationary & Fonts.
This will give you a window entitled Signatures and Stationary with e-mail Signature and Personal Stationary tags. Click on either to vary respective fonts and sizes. The Personal Stationary tag gives you options to change fonts for new e-mail messages and for Replying/Forwarding messages. Just click on the respective FONT button.
