If you have a special UBmail account used for administrative purposes (not using your UBITName), see how to send and receive email in Outlook.
If the account is being added as a standalone account in Outlook (the password to the exception account is known).
If the account is being added as an Administrative/Shared account in Outlook (the password to the exception account is NOT known, and access is provisioned via an administrative group).
When prompted for the email address, it should be entered as itorgaccount@ubitmail.buffalo.edu (unless it still has a departmental domain, e.g., itorgaccount@provost.buffalo.edu), where itorgaccount is the name of the account you are trying to access.
