Address assignment and eligibility

Every individual who has an active association with the university is assigned a unique email address.  The mailbox associated with the address will be activated automatically, no additional action needs to be taken.  To ensure uniqueness of email addresses, and to maintain consistency with the CSU email format, requests for a specific address cannot be accepted.  Email addresses are assigned based upon the name of the individual, as it is officially listed with CSU, and may contain numeric characters.  Once an email address is assigned to an individual, it remains reserved for that person, even if the mailbox has been deactivated.  In the situation where an individual’s name has changed, the email address assigned to that individual will NOT automatically change.  To have a new address assigned, due to a name change, please contact the IS&T Help Desk at 216-687-5050.  Once a new address is assigned, it will become the official CSU email address of that person.  The address previously assigned will become an alias and will continue to accept mail at the mailbox so as to ensure no interruption in mail delivery.

Engage365 accounts, along with OneDrive, SharePoint, Lync, Office Pro-Plus and Office mobile, are activated / deactivated based upon an individual's current association with the university.  Please refer to the eligibility list to determine when you may expect your engage365 and above listed services, to be activated or deactivated.  

Notices are sent before the accounts are deactivated as a reminder of the upcoming deactivation.  It is the individual's responsibility to take the appropriate action to remove any information from the account that they wish to retain.  Requests to have the deactivation date extended cannot be accepted. 

Special note: CSU never sends emails requesting sign in information for any account you may have with CSU.  Should you ever receive an email requesting your sign in credentials, or other personal information, do not reply to it, nor select any link that may be embedded within it.  Mark the item as junk or delete the email.

CSU departments, as do many professors, use your CSU email address to send you information, both that is general in nature and that which is meant to address items specific to yourself.  The option to have any mail that is sent to your CSU email address to be automatically forwarded to a personal 3rd party address is available.  To define a forwarding on your email account simply sign into your CampusNet account and set the forwarding under the email option.  Should a forwarding be defined on an account at the time it is deactivated, CSU will retain that forwarding and continue to forward all mail that is sent to the CSU email address, to the address defined in the forwarding.  Once a forwarding address is defined, mail will cease to be delivered to the CSU email address.  It is the student’s responsibility to verify that the address defined in the forwarding is active and correct.  Please note: wait at least 2 hours after defining, or removing, a forwarding address for it to become active.  If mail is not being received at the address defined in the forwarding, please check the spam settings, along with entries in the spam folder, on the account to verify if the mail is being flagged as spam.  Issues related to mail not being accepted at the address defined in the forwarding address must be directed to the administrator of the system that is hosting that particular email account.

Faculty & Staff

Your email account is activated once you are listed as an active employee with CSU. Based upon your status with the university as a current, or former, employee, the option to define a forwarding address may not be available for your account.  To determine if your account is eligible to have a forwarding address defined, please review the forwarding eligibility list.  Faculty and staff personnel should refer to the University Records and Retention policy before deleting and purging information from within their engage365 account.

Microsoft does make updates/improvements to their system on a regular basis.  As a general rule, these updates are made with minimal, if any, interruption in service.  Should an interruption in service ever be required to install an update the outage will be scheduled, when possible, at a time that will cause minimal impact, with email notices being sent out the CSU community announcing the planned outage.

If you are interested in learning about any updates that are being planned for the Office 365 system (referred to as Engage365 here at CSU) then please feel free to view the updates that Microsoft has planned for the system.

Please note, the above site provides general information as it effects the system that Microsoft manages, not only for CSU, but their entire system.  There may be instances where a particular planned update will not be made available to, or supported by, CSU.

Documentation for addressing specific tasks / issues

Documentation to address a specific task, or issue, is easily accessible via a "help menu" from your account.  To access the help menus follow these simple steps: sign into your account as you normally would; in the upper right corner there will be a "?" mark, select this (on the web select "Help" after you select the "?") and a help screen will appear where you are to enter some basic information related to the documentation for which you are searching.  Example, if you wish to learn how to set your out office, follow the steps above to access the help menu, once there, enter "out of office" and a list of documents that have this phrase embedded within them, or address your request, will be listed.  The document listed at the top of the list is usually the item that would best match your request.
