7 Tools to Sync Microsoft Outlook With Google Calendar

Saikat Basu Updated 29-11-2019

In 2014, the discontinuation of Google Calendar Sync left behind two orphans—Microsoft Outlook Calendar and Google Calendar. It was an instant blow to productivity for those who used both for smart task management. The good news is that you can still connect Outlook with Google Calendar.


The only question you need to ask is why.

Why Sync Microsoft Outlook With Google Calendar?

Keeping two different calendars can be a time suck. But there are some situations which make this handshake necessary. Is it any one of these reasons?

  • You work in two jobs that use either one of the calendars.
  • The two calendars might serve different purposes—maybe, one is a personal calendar and the other is for work.
  • You travel a lot and trust Microsoft Outlook Calendar on the desktop more than the Google Calendar on the web. Though, Google Calendar can work offline too.
  • You have set up a Google Calendar for collaboration on a special task and would like to see the information in Microsoft Outlook.
  • Maybe, you just love calendars and can’t get away from them.

In the busy-ness of life, you would want to see the events in both calendars—together. Keep them synced. Use these third-party tools instead of the bygone Google official plug-in.

Calendar Sync (ver.3.9.3) is a software that allows you to set up one-way sync with either Microsoft Outlook or Google as master. The one-way limitation is removed in the Paid version. The free version also limits you to sync appointments and events within the last 30-days.


The Pro version ($9.99) allows you 2-way sync of all events and even use custom date ranges. The freedom to use multiple calendars and extra profiles is also an extra notch for the Pro version.

Both Free and Pro flavors are available as portable versions too. Let’s highlight the core features of the free Calendar Sync utility.

  • Sync Outlook Categories/Colors to Google Calendar.

    Hi Saikat,
    I'd recommend an alternative choice of google calendar sync option, the EVO Collaborator for Outlook, perhaps you can take a look and add it to the article? thank you.

      Hey thanks for the info.
      It really helped me out, I am sharing a calendar with my wife using one gmail account and this solution keeps me up-to-date weather I am on laptop or on the raod.

    I use google calendar for all of my personal items and outlook is used exclusively by work. I really do not want my personal items to show up on my work calendar so it would be nice to have a one way sync of outlook to google calendar.

    Reason for 2 calendars: My main calendar is my work one (outlook), but I want to be able to add appointments on the fly using Google Home, which I think only supports Google Calendar.

    Why do all these articles suggest that you'd be better off to choose one? My employer uses Outlook. I am almost never the person who puts appointments onto my Outlook calendar. _I_ hate Outlook calendar, so of course I want to get my Outlook events into Google.

    CalDav Synchronizer works great, it's free / donationware. It's regularly updated and will sync Google Calendar, Contacts and Tasks with your Outlook profile.

    gSyncit works great. I've used it for a few years. I found it after the free google sync app from Googlemwas discontinued. I tried a number of others but at the time gSyncit was the easiest and best. Still love it today. It syncs my Outlook 2010 colander and contacts to Google Calendar and Contacts (and vice versa) which in turn I have set up to sync to my iOS devices. It helps me get my calendar from my desktop to my devices seemlessly. They update the program regularly. It was worth every penny I paid for the full version.

      I want to echo the endorsement of Gator5000e for gSyncit. I, too, have used gSyncit for a number of years. The developer regularly issues updates and enhancements. In my case, gSyncit synchronizes my Outlook calendar to two Google Calendars: One contains all event details and keeps my Android devices synchronized with Outlook. The other contains only event start and stop times and gives me a calendar to which I can provide public access.

      gSyncit provides a great feature set to synchronize Outlook tasks with Google Tasks. My configuration syncs several separate lists, with each Outlook category being synchronized with separate Google Task lists. This is part of my Getting Things Done implementation on both Windows and Android.

      Finally, gSyncit also keeps my Outlook contacts and Google Contacts in sync.

    Thanks for this post. Unfortunately I'm one of the many who find that google calendar synch simply crashes outlook (2007) and have found no way to prevent this despite much searching. So google calendar synch is useless to me.

    The problem I've had synching with Outlook in the past is that you can only sync one google calendar. If you have multiple Google calendars, you're out of luck. Synching multiple calendars is something that is easy to do if you use Mozilla Lightning (unfortunately, my business recently required everyone to migrate to Outlook).

      I have used Sync2 for years and had no problems until recently. For whatever reason it will not sync my calendars now. Their support, at least for me, is miserable. I really wish it was better. For me, over the past several years, Sync2 has literally been a set it and forget solution.
