XYZ Corp. has two on-premises IBM Lotus Domino domains. The domain XYZ-NA is
connected to IBM SmartCloud Notes in the hybrid configuration and has users both onpremises and in SmartCloud Notes. Users in the second domain, XYZ-AP, can send and
receive mail to all users in the XYZ-NA domain. Some users from the XYZ-AP domain are
moved into the SmartCloud Notes service. On-premises users in the XYZ-AP domain can
now no longer send mail to the users in that domain who moved to SmartCloud Notes. What
is the most likely cause of this problem?

A.
The email addresses of the users who moved have changed and the directory needs to
be updated.

B.
The servers in the XYZ-AP domain are not allowed to connect to SmartCloud Notes
through the passthru server.

C.
No mail-routing connection exists between the XYZ-AP domain and the mail hub in the
XYZ-NA domain.

D.
No mail-routing connection exists between the XYZ-AP domain and the SmartCloud
Notes service.
