Ever since I got the iphone 5 my phone/icloud calender and contacts will not remain synced with Outlook. I am constantly having to sign in and sign out and unlink and re link to Outlook.

Where are your calendars and contacts duplicated? On your devices? On icloud.com? In Outlook?

Just to confirm, your contacts and calendars on your phone, iPad and icloud.com are correct and unduplicated, but you have duplicates in Outlook?

As far as calenders go. i deleted everything apple out of outlook and started over and each time I close icloud and re-sign in to sync of my clenders I get an "Calender-Icloud" and an "Calender from ICloud".

Are they both listed under the heading "iCloud", or is one of them listed under something else like "My Calendars"?

Go to your calendar on icloud.com and add any calendar events that are on your iPhone that are not on your calendar on icloud.com. After your calendar on icloud.com contains all your events from your phone, go to Settings>iCloud on your phone, turn Calendars to Off, choose Delete from My iPhone when prompted, then after a minute or so turn Calendars back to On. Next, check Settings>Mail,Contacts,Calendars>Default Calendar on your phone to be sure you have selected a calendar listed under your iCloud account name as your default. Then add a new event to the calendar on your phone, and see if it appears on your calendar on icloud.com after a minute or so. Assuming it does, check your iCloud calendars in Outlook on your computer to see which calendar the new event appears on. If it appears on one of the iCloud calendars in Outlook, uncheck the other one to hide it.

Now add a new event in Outlook on the calendar your phone was syncing with and confirm that it apears on icloud.com and on your iPhone. If so, your iCloud calendar should be syncing proplerly now, and you should only see a single, unduplicated calendar in Outlook on your computer. Is that the case?

Sounds like the Outlook plugin isn't working properly. You could try a couple of things:

1. Go to Start>Control Panel>Add/Remove Programs, uninstall iCloud, the download and install the iCloud contol panel for Windows again from here: http://support.apple.com/kb/DL1455. Then sign back into your iCloud account and check your syncing settings again.
2. Uninstall iTunes and all of its components as by following this guide exactly: Windows XP or Windows Vista/7, then reinstall iTunes. You must follow this guide exactly or it will not be successful. (Uninstalling iTunes will only remove the application; it will not touch your iTunes library or data.) This will replace the Outlook plugin.

Then try your calendar again and see if it will sync properly now.

Good news! And you're welcome. Are you contacts working to, or do you still have duplicates to deal with?

You're welcome.

You might need to try uninstalling, then reinstalling the iCloud control panel for Windows again.
