I always sync my E7 with Microsoft Outlook 2007 by using Nokia Suite. I have recently got an iPad so shared my contacts and calendar with iCloud from Outlook. This works brilliantly and any changes appear instantly on the other device when made.
However, when I now try to sync my E7, it won't work. Nokia Suite shows an error when I change the sync from Outlook/contacts (or calendar) to Outlook/iCloud. If I leave the setting as they are, it puts all of the data back and doesn't see the iCloud data.
Is there a way to do it? If not, I think I'll end up having to go down the iPhone route when I next change my phone.
