If you are faculty, staff, or student, then you have a Union email account. This gives you access to an online Office 365 account, which, among other things, gives you access to your Union email online. You can access your Union email via a web browser by going to this link. If you are somewhere and don't have access to the link, then Google Office 365 login.
To access your online account, you must use Multi-Factor Authentication (MFA). Please visit this page for help on how to set that up.
If you need Microsoft Office on your computer, then you can get it through your webmail. See how at this article.
One other benefit of your Union Office 365 account is 1TB of online storage through OneDrive.
Please note that at this time you cannot change your Union password using the change password option in the webmail. See this article for information on how change your password.
