How can I get Outlook calendar to sync with iPhone and iPad?

Question

I think I have tried evert known setting but syncing seems very selective.  I have googled for solutions, too.
Currently, I load an even into my Outlook calendar (and have the right boxes checked in iTunes) but I am damned if the even will transpose to either my iPhone or my iPad! My Outlook also displays the iCloud calendar too.
Is there a definitive instruction that is, effectively, a child's guide to setting up Outlook to transpose events to the Apple devices AND vice-versa?
In my iPhone and iPad, I have the iCloud sync box ticked.  In my phone calendars I have both PC and iCloud ticked.  Events show in my Outlook and Outlook iCloud but not in the &^&^*&^(*&(*)&(* iPhone or iPad.  I have had some close shaves over missing events and want to have this solved.
Pleeeeease?

An interesting additional symtom is that items loaded in the PC (which immedialely duplicate to the iCloud calendar on eht PC - no worries, there) do not transpose the devices (as above) but, loading an item into the phone, it goes to the PC (which is fine, too).  But not to the iPad.  Interestingly, there fewer calendar display options on the iPad than on the phone.
I talked to Apple a few months ago (after ISO 5) - mainly about the 6000 plus addresses that suddenly appeared in my Contacts - and his advice was do all contact and calendar actions on the PC.  "icloud is still faulty"
So there we are!   I must have items and reminders in my PC - it is my main work station - and need them on my devices to avoid conflicts when away from my office.
