You have to be a bit more specific than that. For starters, what do you mean by O365 setup? Are you referring to the Office 2013 click-to-run installation that comes with O365 or something else? Or you mean setting up Exchange Online and other Office 365 services?

If your mailboxes are located on prem and you dont plan to migrate (any of them) to O365, you will not need any changes to OA or any other components, just install the Office suite and you should be good to go. If you are referring to moving to O365 instead, best thing to do is to configure Hybrid, and the Exchange deployment assistant is a good starting point:

let me clarify...

setup in a hybrid mode with about 20 accounts already moved to O365. Most users are still on premise and in different locations. Free busy works fine from the location where hybrid server s located but a user who just moved to cloud in a remote site that has CAS servers as well... does not see free busy to premise.

for the hybrid mode setup is outlook anywhere necessary.... for autodiscover to function properly?
