Dear Kim Moberg,
All the guides you mentioned are currently being updated to reflect the latest changes in CloudGuard SaaS. See my reply in Why does it take 8-10 minutes to get through after protect(inline) mode is enabled.
The use cases of those 3 guides are a bit different which explains the fact that they are different documents.However, after update, the admin guide should have links to the Manual Configuration guide for Office 365 and to the Quick Start Guide.
Thank you for the feedback on the link to Help. I will definitely see what can be done to make it more accessible.
We really appreciate you sharing feedback on CloudGuard SaaS so that we can improve the product!
