  • Hi Sami,

    You need to reboot the CAS server first. As there is only one CAS server, when reboot the CAS server, users can not connect to exchange via the CAS server anymore. So, in order to reduce the impact, it's recommended to reboot the CAS server during non-working hours.

    Then, reboot mailbox servers, you can refer to the following blog to reboot the server under maintenance mode:
