Assorted notes:

  • http://www.pppindia.com/calendar-sync/index.html - free version syncs 30 days; $10. Has a “portable” edition.
    • I see a problem report: “Failed in 1 way sync O->G to delete a single event within recurring appointment”
    • A little “hacky” setting up recurring sync with OAuth.
    • Says it works through proxy, but it does not go through my work proxy nor my home proxy. Sync is OK without a proxy.
      • I edited the config file and changed to and that didn't seem to help.
      • Then I turned on Fiddler to debug, and loaded my Google Calendars and chose the one I wanted successfully. After that, Sync seems to run OK, even when Fiddler isn’t running.
  • http://www.fieldstonsoftware.com/software/gsyncit3/ - $20
  • http://sourceforge.net/projects/googlesyncmod/ a.k.a. http://googlesyncmod.sourceforge.net/ - open source.
    • There is a time tolerance of 2 minutes to cope with time differences on Server and Client side, therefore please wait at least 2-5 minutes, before you Change an appointment, contact or note and resync afterwards
  • CompanionLink says Sync Outlook calendar, contacts, notes, tasks, journal, and contact photos. $50
    • Some Amazon users complain of duplicate events
    • They have been around since the days of Palm, so they have a successful business.
  • https://outlookgooglecalendarsync.codeplex.com - open source. Reportedly does not require admin. One way (in either direction); NOT bidirectional and not both uni-directions at the same time. Crashed on startup (I think this was because I had an open calendar reminder, blocking the Outlook GUI. Or maybe I cured it by moving it to a directory with a short path.)
  • http://technology.s-sheth.com/publish-outlook-calendar-to-gcal - one way, Outlook to Google, 90 days only. Zero software to install on your work PC.
  • Sync Reminders with Google Tasks: http://tasket.mobi/faq - free
  • http://sync2.com/ - $40
  • SyncMyCal - I own a copy of this. 32 and 64-bit support (separate download pages). Discontinued.
  • http://www.gooout.net/index2.php $40
    • Deal-killer: “Google Calendar is always the master calendar. It’s only possible to delete or update items via Google calendar.”
  • EVO Collaborator for Outlook - $30. I’m not certain this will work. Google does CalDav. This adds CalDav to Outlook. It should work.
