I have an office with 100 users, all on Exchange 365. Currently, passwords are set to never expire. I need to turn that off and set an expiration policy. Here's the problem; they're not using Azure (no single sign-on), and most users don't remember what their current password is. So if I set a policy to expire passwords, most will be stuck at "Enter your Current Password" before entering their new password.
At the moment, my only option appears to be to reset everyone's password to a default and make them go from there, but that's going to create a LOT of headaches and downtime.
Any ideas would be greatly appreciated. Thank you
