I have successfully used Kies to sync Outlook with my Galaxy SII in the past, but for the last couple of days, whenever I try to Sync, it takes forever to "prepare to sync" and then after 1 or more discrepancies that I have to select whether to go with the Outlook or phone, I get a message that says, "An error occurred while syncing GT-I9100's schedule. Syncing Cancelled." It doesn't tell me what the error is, or how to avoid it. I don't think I'm able to sync at the moment (or at least, I can't trust that it's fully synced). I've tried selecting only a certain date range but that doesn't seem to make any difference. Can anyone help, please!
