Thank you Slotu - I wanted to remove the Outlook syncing but keep the photostream and bookmarks syncing. So I followed your advice, omitting the uninstall, and it worked great.
I did print to pdf the list view of appointments first, as well as my contacts list, just in case I ended up with nothing and had to redo everything. We do have multiple backups, but I couldn't remember when I turned on iCloud so I wasn't sure how helpful that would be so figured a print out would be tedious but doable.
I did find that I had to redo my email contact groups - but that function wasn't working in iCloud before either - I'd type the group name in and it would tell me it was blank. A small price to pay for getting to work right again.
I also had to move all my appointments from the 'Calendar from iCloud' folder to my default calendar. List view is wonderful 🙂 Select all and drag to the right folder. Only one appointment refused to move and I had to reenter it, but one is not bad. Then I had to turn on all my reminders again too (again iCloud had managed to randomly turn off most of them when it was running anyway). List view wins again. I simply pulled up the column for reminders and went down turning them all on again - it had remembered what they were set to before iCloud got involved so all was good.
I have Outlook back and running normally again and it didn't take long at all.
So thank you once again.
Just to make sure that everything would stay where it was I went into the iCloud settings on the iPad and iPhone as well and turned off all the Outlook options leaving only the photos and bookmarks (wouldn't have minded keeping the notes, but decided it wasn't worth setting up the email address to do so). Again, when I switched those off it asked me if I wanted to keep a copy on the device so I just said yes, and everything looks great.
