My Exchange 2019 site running on CU11 SU3 (2 units server).
User start complaining that they wont be able to reset password through OWA if admin select the option User must change password on next login during the password reset. No issue for user to login if admin did not select the option. Normal password change from OWA options do not have any problem, running well. Same issue whether admin reset the password using ECP or ADUC.
Testing direct access to both servers also result the same error as per attached.
User said previously no issue for reset password through OWA with the option selected.
Just upgrade the server to CU11 SU4. Issue still remains.
Need help. Thanks in advanced.
