When a user attempts to reset their password they see the following error:
"Password Reset Server is not available now. Please contact your administrator. Error code: 0x8200205f"
This can occur if the password reset service account is using "SESSION" mode.
This may be due to changing the configuration of "Default user profile".
If you wish to use "SESSION" security mode for the ESSO users via the "Default user profile", you need to ensure that the "password reset" service account does not use the same policy as the users.
Make a "new" "user profile" that is configured with "PASSWORD" security mode, and apply this policy DIRECTLY to the password reset service account.
This is expected behavior. The password reset account does not use a Windows session, and therefore cannot use SESSION security mode.
