If you wish to send emails that follow a similar format, you can choose to use a pre-defined template which will quickly add in standard text to a new email and will save you from repetition. There are three pre-defined templates configured as default in Outlook Web App, however you can customise these templates to make them suitable for the emails that you send, for example to create standard appointment information
