The Account Portal has been updated to grant users of an inactive site access to view service history information, associated photos, manifests, and report attachments. Other options, such as the ability to create a request or view AR information, are not available.
Access to inactive sites is determined by the account class to which the site belongs. When the 'Enable Viewing Inactive Site' field in the Account Portal tab is set to "Service History Only," portal users will have restricted access upon logging in.
