All I needed was one-way sync of Outlook to my Android phone & Google apps. After years of using this, I can say that it is fine for all except calendar. (Note also that it was complicated to setup -- so many options and the implications of some are not very clear). As to calendar, it seemed good at first. However, after a couple months (for weekly-repeating event) or six months (for monthly-repeating events) or ten years (for yearly-repeating events), it messes up. Per the author, it only syncs repeating events for a limited horizon (e.g. 2 months). That's an immediate issue for me, anyway, as I make plans more than 2 months out and need to see commitments beyond that. Then, each night, VCO attempts to extend its horizon by adding events back in. It actually puts them in where they need to be, but also adds extra entries all over the place. The author (who has been very responsive) says he can't resolve it because it is an incompatible API with Google vs, Outlook. I expect now to write my own app for calendar sync. I'm just glad I didn't have two-way sync on, or Outlook would be hosed as well. Use VCO, but don't sync calendar!!
Have been using this on a daily basis for about a year - so obviously I find it useful and think it's just about the best thing since sliced bread. Had a few teething problems at first and found Vecal support quick to clarify any issue I had. This seamlessly synchronises Outlook with VCO, and if you wish, your Google account. There's plenty of options, which now seem clearer than before, different views including pinch and zoom, and a selection of widgets are available as well as a dashboard. The only improvement for me would be the ability to make the calendar and contacts the 'default' on the phone so I could interrogate them from other apps (voice control), (so for this reason I get VCO to sync to the default as well). Update 2016 - still using this app after 4 years - it's great and syncs with Outlook flawlessly. You can also link contacts/tasks/calendar entries etc
OK. Confusing to use Works, but needs better instructions
Best outlook sync, Android M Good app, the best in its kind
Best outlook sync This the only Outlook sync on the market that works for all outlook functionality. This should be included in the Android OS.
