Mail Retention

Items stored in any system or personal folder will remain in the account, regardless of the age of the item, until an action is taken by the owner of the account to purge the item or the account is deactivated.  The exception to this is the "Deleted Items" and "Junk Email" folders.

Items stored in the folder "Deleted Items" will be purged by the system after 30 days.  If you need to recover an item once it has been purged from this folder, you have an additional 30 days to recover the deleted item.   Once this additional 30 days has passed, the item cannot be recovered.  Please note, any folder that is listed under the "Deleted Items" folder (that is a sub-folder to that of "Deleted Items") will follow the same policy as that of "Deleted Items" and the material within these folders will also be purged after 30 days.  To avoid this, do not create any personal sub-folders under "Deleted Items".

Items stored in the folder "Junk Email" will be purged by the system after 15 days.  Once purged these items cannot be recovered.  Mail directed to this folder, either by the owner of the account or the system, is considered spam / phishing.  If an item that is considered to be a legitimate piece of mail is directed to this folder, follow the directions to mark the item as not being spam.

Engage 365 Activation / Deactivation Information

Engage 365 accounts, along with any associated services, are activated / deactivated based upon an individual’s current association with the university.  

Accounts for eligible individuals are activated automatically once they are listed as having an active association with CSU.  It can take up to one business day after the status has been set for the account to activate.  

Notices are sent to the CSU email address before any account is deactivated.  This notice will provide information related to a deactivation date and, if eligible, instructions concerning activating an alumni account.  It is the individual’s responsibility to take the appropriate action to remove any information from the account that they wish to retain.  It is strongly recommended that this action take place well in advance of the estimated deactivation date as listed in the eligibility list.

Alumni accounts are available to all former students.  These accounts must be activated by the individual by following the information provided in the deactivation notice.  Should the account already be deactivated, simply sign into your CampusNet account and select the option listed under the Email tab to activate the account.  Note: once an account is activated as an alumni account, the primary address will be "" and any previous address will become an alias address for incoming mail.  Please note, once your account is activated with an alumni address and you are accessing your account via a mobile device and / or a client, you will need to remove the previous sign in set up and re-establish access using your alumni address. 

Please refer to the eligibility list to determine when you may expect your Engage 365 account to be activated / deactivated and what services will be available to your account upon activation, based upon your status with the university.

Email Address assignment

To ensure the 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 officially listed and may contain numeric characters.  The automated system attempts to assign an email address based upon the initial of the first name and the entire last name.  If that combination is already reserved, an attempt is made using the middle initial; if that combination is already reserved the process repeats using random numeric characters.  Once an address is assigned to an individual, it will never be removed or reassigned to another individual, even if the account is not currently active.

New email addresses will only be assigned in the event of a name change, and must be requested.  To request a new address, use one of the methods listed below in the "Reporting an issue" section.

Once a new address is assigned, it will become the official CSU email address, 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.  Please note, once a new address is assigned and you are accessing your account via a mobile device and / or a client, you will need to remove the previous sign in set up and re-establish access using your new address.

Forward to a personal account

The ability to define a forwarding to redirect mail to a 3rd party account is available to all students and to selected faculty / staff.   To determine if your account is eligible to define a forwarding address, please review the forwarding eligibility list

To define a forwarding for your CSU email account sign into your CampusNet account, select the Email tab and follow the directions listed. 

Wait at least 2 hours after defining, removing or changing a forwarding address for the change to become active.

Once a forwarding address is defined, mail will no longer be delivered to the CSU email address, any mail that resides in the CSU mailbox before the forwarding was activated will remain in the CSU mailbox.  

It is the account owner’s responsibility to verify that the address defined in the forwarding is active and correct.

Once mail is redirected to a 3rd party account, it leaves our domain and we are no longer able to track or address any issues related to the delivery of the item.  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 determine if the mail is being flagged as spam.  Issues related to mail not being received at the address defined in the forwarding address must be directed to the administrator of the system that is hosting that particular account.

CSU reserves the right to send CSU related information to any CSU email address.  Should your CSU email address be forwarded to a personal email account, this mail will also be redirected to your personal account.

Upon separation from CSU, should you no longer wish to receive CSU email at the account defined in the forwarding, sign into CampusNet and remove the email address defined in the forwarding field.   Otherwise, CSU will retain the forwarding address defined and continue to forward all mail that is sent to the CSU email address, even after the CSU email account is deactivated.

Faculty & Staff

Faculty and staff personnel should refer to the University Records and Retention policy before deleting and purging information from within their Engage 365 email account.

Individuals whose status is listed as that of a retiree or emeritus, will retain active email accounts after their separation from CSU.  These accounts will only provide email and calendaring services.  All other services / apps that were associated with the email account will be deactivated upon separation.  It is the individual’s responsibility to take the appropriate action to remove / download any information they wish to retain.

Focused Inbox / Folder 

Focused Inbox separates your inbox into two tabs—Focused and Other. Your most important email messages are on the Focused tab while the rest remain easily accessible—but out of the way—on the Other tab.  Once you start marking items as focused, the system will "learn" from the previous messages and as new mail arrives in your inbox, will make a determination based upon past items marked as focused and more those items into focused folder or remain in the "other" folder, which is less important mail.  If this option is on, regardless of what folder the mail is sorted into, all mail continues to go into the Inbox, if you open the Inbox, you will find all mail listed.   Unless you have a specific need to have mail separated into these two folders, the recommendation is to turn this option off, and simply use the Inbox to view your mail.

 Mass Email

Cleveland State blocks spoofed emails from arriving in CSU mailboxes. This is to prevent phishing campaigns. A spoofed email is sent from an outside service but with an address ending in "".

We do allow exceptions. Some university email campaigns use an external mass mailing service with a CSU sending address. To arrange a spoof exception please call the IS&T help desk at 216-687-5050 and ask for an email ticket to coordinate a mass mailing campaign.

We will need to work with whoever sets up the email campaign as well as the vendor that sends the emails.
