You can identify what Rutgers email addresses you have access to at https://netid.rutgers.edu/index.htm, click the "Manage Email Addresses" link. You will be able to identify your alias, delivery, and official Rutgers email addresses.
If you are a current student, faculty member, staff member, guest or alumni with Rutgers and you have activated the ScarletApps service at the "Service Activation" link on the same website, you will have access to a Scarletmail account. ScarletMail is the official email service for Rutgers affiliates. You can access this account at https://oit.rutgers.edu/scarletapps by selecting the “Mail” application. You would log in with your email@example.com and your NetID password.
If you are a current faculty or staff member within the university, you are most likely auto-provisioned for a Connect (Office 365) account. Connect is slowly removing and replacing RCI accounts. Connect accounts are mostly administered within a department. Most departments have migrated to Connect, but the goal is to have all departments migrated in the near future. For existing users in a department that are not yet migrated, you will have to wait until your department has migrated your account or request one from your departmental IT personnel.
Your alias addresses are personalized email addresses typically in the form of “firstname.lastname@example.org” to provide an alternate, professional display. It allows the option of a different public address aside from your typical NetID address to provide to others. All mail sent to any alias address that you publicly display will be sent to your delivery address(es). Your delivery addresses can be your Scarletmail account, your Connect account, and/or a personal account depending on your role with the university. Your official Rutgers email address is the email address displayed for others that wish to locate your contact information through http://search.rutgers.edu/index.html.
