Is it possible to sync the calendar and contacts that are currently on my iPhone and upload (sync) with iCloud? My phone is getting the calendar, contacts and tasks from my work Exchange server so my phone is all updated but I thought maybe I could turn on the iCloud sync on the phone and it would sync, am I correct in this assumption? The reason I don't try it is because when I tried the Outlook sync with iCloud it caused some very unwanted work and headaches. I would like to know if anyone has tried this and had a successful or failed result.
If you have an iCloud account and setup iCloud on your device(s) then yes, the items that you have enabled to sync (Mail, Contacts, Calendars, Reminders, Bookmarks, Notes, Photostream & Documents & Data) will sync with iCloud and changes you make on your device(s) will reflect via iCloud online and vice-versa.
it seems to be 2 separate calendars and contacts. Nothing happened when I turned them on on the iphone. I was hoping it would take my calendar from the phone and sync it to icloud. Not really sure I need to do this or even want to do this but I was thinking about this today so I am asking the experts
Do this: when you initiate the Calendar app, select 'Calendars' in the upper left corner. Under the heading, iCloud, how many calendars does it show? If it is more than 1 AND if both calendars are identical in regard to their entries, delete one of them. It may be easier to logon to iCloud online via a Mac or PC and correct the issues you're having with duplicates. I hope I'm not misunderstanding your dilemma and hopefully, others will chime in to help, as well.
If you have the option, it's far easier to just use iCloud's mail, contacts and calendar. I had mine on Gmail/Google before iCloud and things got incredibly complex - with major problems - once iCloud came along. It took some doing, but I eventually eliminated all Google/Gmail stuff and have only iCloud. Much better.
