Hi, I have an iPhone 4S syncing via iCloud to Outlook 2010 for PC (Win 7, 64 bit. & iTunes 64 bit also installed). The issue I have refers only to recurring appointments not single "one off" items. I have appointments that recur in a pattern (the pattern is not important here). Any new recurring appointment made either on the phone OR on the PC WILL sync correctly and appear on the other device. I can edit any field of the appointment (start/end time, location, notes etc.) of the series, again on either phone or PC, and the changes sync and are reflected on the other device. If however, I edit a single occurrence of the series, (again on either device and specifically make or change a note) and save my change for that occurrence, the other device will not update or reflect the change. No error or other dialog box appears. The syncing spinner on the phone runs. and the change is saved on the device on which the edit was done. Does anyone have any suggestions or experience of this issue and, more importantly how to fix so as ALL changes are reflected after syncing?? Looking forward to your replies & thanks in advance.
