Since 1 September 2021, the email domain has been changed to @live.hkmu.edu.hk, but addresses with @live.ouhk.edu.hk will remain effective until 31 December 2022. During the transition period, all emails delivered to @live.ouhk.edu.hk will be redirected to users' mailbox, while @live.hkmu.edu.hk will be set as the default user email address for outgoing emails. The login ID of existing accounts will remain as xxxx@live.ouhk.edu.hk until the user resets the password through the HKMU O365 page, at which it will be changed into xxxx@live.hkmu.edu.hk. All remaining login IDs will be updated to xxxx@live.hkmu.edu.hk on 31 December 2022.
