Gmail is a web based email system. At Ryerson University, Gmail comes as part of Google Apps available through my.ryerson.ca portal. Once logged in, users can click on the Apps tab from the top menu and find Gmail.
Your Apps account (including Gmail) has unlimited storage of file and email message space that you can use. The only restriction on files is that they cannot be larger than 5TB in size (5,000 gigabytes).
More information about Gmail is available on the Google Apps website.
