Current version does support Outlook 2016 and 64 bit clients
(as well as 2010 and 2013)
IMSMO and Traveler can be used together so long as they
are on different servers (IMSA, the IMSMO server component on mail and
Traveler on remote).
Its true that IMSA and Traveler cannot be on the same
server, since as you suspected IMSA uses some specially configured Traveler
components.
The comments about the DMZ are just a statement of your
environment though (albeit a common one). IMSMO is a desktop client
and can be used wherever a Notes client can be used - its not a mobile
client and the fact that DMZ access is different might certainly be desired.
But, if you want your tablets to access outside the DMZ,
you can set up a sprayer that has access outside the DMZ and routes the
requests to the IMSA servers behind the firewall (IBM Mobile Connect, etc)
Can IBM Traveler be used with the Outlook client? No.
