Reviewing through your description, for the Office 365 add-on available for Jive you might find the Jive for Office 365 documentation helpful in configuring this add-on. Specifically,
Is there any application which is required inside sharepoint to generate some kind of token which has to be used in jive add-in for share point online and office 365. If there is any app such as Jive for share point online (sharepoint side jive app) please provide us or the ways or link from where we can download it.
However, if you are seeing a specific error during the configuration process I would recommend submitting a case in your customer group here in the Jive Community for additional investigation and follow-up by a member of our support team.
