| Microsoft has identified a problem with how its email systems interact with email services like AOL and Yahoo that are using the new anti-spam approach. Microsoft technicians believe they have a solution for the issue. It will need to be applied to all Microsoft Exchange email systems, both ones in Office 365, like Cornell's, as well as organizations that host their own Microsoft email. Microsoft has not yet provided an estimate of when this fix will occur. | Microsoft has identified a problem with how its email systems interact with email services like AOL and Yahoo that are using the new anti-spam approach.

| For details on which messages are affected and what Yahoo! and AOL users can do, please see: \nhttps://www.it.cornell.edu/services/elist/howto/troubleshooting_detail.cfm?id=275523\n\nSummary: \nYahoo! and AOL recently changed their “DMARC” policy to more aggressively defend against email spoofing. Spoofing is when the email “from” address is forged. \n\nThere are no changes that Cornell could make to our systems that would fix this situation. Individuals who route their cornell.edu mail to non-Cornell accounts should consider their options, described at the link above. | For details on which messages are affected and what Yahoo! and AOL users can do, please see: \nhttps://www.it.cornell.edu/services/elist/howto/troubleshooting_detail.cfm?id=275523\n\nSummary: \nYahoo! and AOL recently changed their “DMARC” policy to more aggressively defend against email spoofing.
