Sync With the Smartphone Apps

This will need a change in your calendar habit. But it gives you the simplest solution while on the move. Like most things these days, the solution sits in your hand 24×7. Your smartphone. Pick one of the three methods.

1. Use the Calendar Mobile Apps

Microsoft Outlook and Google Calendar both have apps for Android and iOS. Installing both apps is a simple solution, but with timely notifications and smart scheduling, you can configure both calendars for specific events.

Microsoft also introduced shared calendar support to its Outlook client recently. Now, your contacts can get access to specific Microsoft Outlook calendars too.

Download: Microsoft Outlook for iOS | Android.
Download: Google Calendar for iOS | Android.

2. Use the iPhone Calendar

The Calendar app on an iPhone and iPad can display a combined Google Calendar and Microsoft Outlook Calendar. Go to Settings > Mail > Accounts > Add Account > Choose both Google and

Log-in to both and allow the sync. Any events added to either calendar will appear in your Calendar app.

3. Use Microsoft Outlook on Android

Install the Microsoft Outlook app from the Play Store. The app can connect to accounts on Office 365, Microsoft Exchange, iCloud, Yahoo, and Gmail. Choose Gmail with your log-in credentials to access both calendars.

Why Do You Use Two Calendars?

That’s the productivity question. Yes, it can help to keep all your calendars updated but isn’t it another overhead you have to handle? Both Microsoft Outlook and Google support multiple calendars, so using that option may be simpler to managing events on two different services.

I suppose it comes down to productivity around your schedules and events. And, the leftover habits for a preferred calendar tool.

Tell us your reasons. And tell us in detail how you make two different calendars play well together. Which calendar do you prefer?

    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).
