No, IBM Domino Gateway configurations and Office 365 adapters are not the same thing. They serve different purposes and are used in different contexts.
IBM Domino Gateway is related to the configuration of IBM Domino servers. It involves setting up network interface cards (NICs), IP addresses, and TCP ports to manage connections and improve performance.
On the other hand, Office 365 adapters are used to enable connectivity between the IBM Security Identity server and the managed resource, such as Office 365. This involves installing and configuring the adapter on the IBM Security Identity server.
So, while both are related to configuration and connectivity, they are used for different systems and purposes. I hope this clarifies your question. Do have a look at the IBM resource for further information. 21016540.pdf (ibm.com)
