There is a problem with ActiveSync and iCalendar files, at least with Outlook/Exchange:
- you receive an email with an iCalendar attachment, .vcs or .ics file.
- you accept the meeting request or double click and add the attachment
- New appointment shows up in Outlook, but does not sync to all mobile devices
The question for sysadmins here is that is there anything you can do in Exchange or Outlook that would make iCalendar-originated appointments sync like ordinary appointments?
Below is an example of a barebone iCalendar file that synced ok with an iPhone OS4 but failed to sync with Nokia devices:
BEGIN:VCALENDAR VERSION:1.0 METHOD:PUBLISH BEGIN:VEVENT UID: SUMMARY;ENCODING=QUOTED-PRINTABLE:Header ORGANIZER: LOCATION;ENCODING=QUOTED-PRINTABLE:Location DTSTART:20101001T070000Z DTEND:20101001T140000Z DTSTAMP:201010011T072221Z DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Description END:VEVENT END:VCALENDAR
The problem is annoying for any user who receives iCalendar attachments. Unfortunately, I'm not in a position to know which combinations of the handset model, ActiveSync, iCalendar, Outlook and Exchange versions are affected. But I've seen quite a few support requests lately about this. The standard answer is that you can get the appointments sync by editing them manually in Outlook, but this is just not good enough.
