| This issue is affecting some students who use Cmail and some faculty and staff who have their cornell.edu mail delivered to a non-Cornell address instead of to their Office 365 account. \n\nMicrosoft's spam system checks these messages and puts messages flagged as possible spam in a separate delivery queue. This Microsoft queue processes possible spam from many sources, not just Cornell. It has been unable to process mail within its four-hour window before a non-delivery notice is returned to the sender. \n\nThe result is that some legitimate messages, flagged as possible spam by Microsoft, may be being rejected and returned to senders before they are able to be processed. CIT has escalated the issue to Microsoft. | This issue is affecting some students who use Cmail and some faculty and staff who have their cornell.edu mail delivered to a non-Cornell address instead of to their Office 365 account. \n\nMicrosoft's spam system checks these messages and puts messages flagged as possible spam in a separate delivery queue.
