Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Ron,
As mentioned above, if users are synced from local domain to Office 365 with ADFS web SSO (Single-Sign On), we can prevent them from changing password in local Active Directory.
However, if users are pure cloud users, in another word, those users are not created in your local Activate Directory, it’s not feasible to prevent them from changing passwords in Office 365 web interface. In this case, I’d like to invite you submit this idea at our UserVoice. Many great features came directly from our customers. Your understanding is highly appreciated.
Regards,
Fraser
