Full Description:
Cornell technicians are working on removing a block placed on email being sent from Cornell accounts to Network Solutions email customers. Email to a number of domains is being affected.\n\nWhile efforts are in process with the outside services, Cornell account holders whose email forwarding has been interrupted can access their email through Outlook Web App: http://outlook.cornell.edu . \n\nCornell account holders who are attempting to send a message to someone using one of the affected services may want to investigate whether the recipient has an alternate email address on a service that has not instituted a block, or send from a non-Cornell account.
