Final answer:
Not all Office 365 features are enabled using IPv6. Hence the correct answer is option 1
Step-by-step explanation:
The statement is true. Not all Office 365 features are enabled using IPv6. IPv6 is the latest version of the Internet Protocol, which provides unique addresses for every device connected to the internet. However, some features in Office 365 may still rely on IPv4, the previous version of the protocol. This is because IPv6 adoption is still not universal, and many networks and devices continue to use IPv4.
Hence the correct answer is option 1
