When you register for or are waitlisted for a class at COS, you will automatically be provided with a Microsoft Office 365 account for your student email. Your Microsoft Office 365 account offers many other applications and features as well. Please wait 24 hours after registering for this account to be created before trying to access it. Your COS student email account is used for all official communications from the College, so please be sure to check it regularly or have it forwarded to an account you check often. For more information about waitlisting, see our Waitlist Procedure page.
Your COS student email address will be your mySiskiyous username, followed by @ins.siskiyous.edu - firstname.lastname@example.org
