Supported Operating Systems

Office 365 does not have a specific operating system requirement, except that the operating system that is being used, must be supported by its manufacturer.  However, there may be advanced Office 365 configuration options, features, scenarios, or tools that have explicit dependencies on an operating system or behave differently on different operating systems.

The Microsoft Service Pack Support Lifecycle Policy requires you to install Office Service Packs within 12 months of its release.  Office 365 requires you to be in compliance with this policy.

Engage365 Eligibility

Engage365 accounts, along with any associated service, 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 account, along with any associated services, to be activated / deactivated.

Engage365 accounts, and associated services, are activated automatically once an individual is listed as being active within CSU.  This process takes one business day after the status has been set, to take effect.

Notices are sent before any account is deactivated.  It is the individual’s responsibility to take the appropriate action to remove any information from the account that they wish to retain.

Alumni accounts are available to all former students.  These accounts must be activated by the individual by following the information provided in the notice that is received when the account is set to be deactivated.  Should the account already be deactivated, simply sign into your CampusNet account and select the option to activate the Alumni account listed under the Email tab.  Please refer to the eligibility list for information concerning resources available to the Alumni account and deactivation policy.

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 any other personal information, do not reply to it, nor select any link that may be embedded within the email.  Mark the item as junk or simply delete the email.

Email Address assignment

Each individual who has an active association with the university is assigned a unique email address.  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 will remain 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.

Reporting an issue / seeking assistance

If assistance is needed to address a question concerning how to perform a specific action, please review the information listed within these pages.  Should the information not be listed, or could not be located, we also recommend using the online help menu available within every account, accessible via a browser or the Outlook client.  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 the “?” and a help screen will appear where some basic information is to be entered that is related to the information being searched for.  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 will be listed.  The document listed at the top of the list is usually the item that would best match your request.

If the above does not address the issue, please contact the IS&T Help Desk at 216-687-5050, or go to and sign in using your CampusNet credentials, to report the issue.

CSU departments, as do many professors, use your CSU email address to send 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 the change 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.  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.  Should you wish not to receive this mail at your personal account, you will need to remove the forwarding or create a rule on your personal account to filter this mail.

Faculty & Staff

Email accounts are activated once an individual is listed as an active employee / affiliate 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.

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.  Other services that were associated with the Engage365 account while the individual was actively associated with CSU, such as OneDrive, Office Products and SharePoint will be deactivated upon separation.  It is the individual’s responsibility to take the appropriate action to remove any information from the account that they wish to retain.  Please refer to the eligibility list for additional details.

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.
