Enterprise Email

Microsoft Exchange

Category: Collaboration Tools

Enterprise Email services encompass the support of all standard email services including basic messaging, address books, mobile access and scheduling of personnel and resources within and among departments. The consolidated mail service will take all reasonable means to protect the security of the mail system and its customers. This will include, but is not limited to, running anti-SPAM/anti-virus software on the servers and requiring proper authentication to the mail services. Conversion and on-going operational costs will be funded through a full cost-recovery line of service. Statewide Enterprise email is currently running the Microsoft Exchange platform.

  • Includes support for any Outlook client 2007 and above, Outlook Web Access and Outlook Anywhere (Web Access can be modified/omitted per department or mailbox)


  • Statewide email will maintain current virus and SPAM definition files and filtering rules on the messaging servers to provide protection against external as well as internal attacks.  Quarantine services are provided to allow potential SPAM to be reviewed
  • Secure web delivery methods are available to ensure email is transported securely to external sources
  • The Internet Mail Gateway is configured to block attachment extensions which pose a risk to resources on the network. DoIT reserves the right to apply filters on certain types of files if the file type poses a risk. A file transfer utility is available to securely transport these file types (filet.illinois.gov).
  • Access to each mailbox requires a valid user ID and password.  A domain trust can be configured between the Statewide Enterprise email domain and the department's domain.  This will allow single sign-on and department managed password policies.  All email accounts are subject to the Statewide password policy (i.e., change every 60 days, cannot use any of previous last 12, must use 3 of the following 4 character types:  uppercase, lowercase, numbers or symbols)
  • 3rd-party messaging applications (for example, AOL Instant Messenger, Microsoft HotMail) products are a security risk.  It is strongly suggested that departments create policies that discourage the use of 3rd-party messaging applications


  • A continuous replication to an offsite location, including a lagged database copy, is in place for recovery
