Good morning. We are being notified by several users who are receiving notifications in Outlook about the expiration of their password indicating "password expires in X days", where X is usually 5 and 6 digits (1030378 days, 696505 days, 1054889 days...) We work with Office 365, in a hybrid environment of Office 2013 and Office 2016 software. Our password expiry policy is the common one of 90 days. Greetings. Thank you.
@ErnestoMartinez Hello! Can't say for sure but probably a bug and I believe what you're seeing is seconds until expiry and not days. If common client troubleshooting steps won't make it disappear I would probably open up a ticket with Microsoft support.
