Here are two great resources for getting started with Outlook for the web, the email service available to all students and staff at SCU.
After successfully logging into your email account (check out the article about this here) you can visit the help menu, located in the question mark icon in the top right hand corner of the page.
There are a number of useful links and features here including contact info for the Service Desk and the "Tell me what you want to do" help feature where you can search for an exact topic like "send an email".
The other resource is Microsoft's own training site on Outlook on the web. You can get to that site by click on "Help" as shown above or by visiting this link.
