If you manage two different calendars, things can sometimes fall through the cracks. What is the best way to achieve the perfect Outlook-Google Calendar sync?

We've got a few options that you can check out for yourself. Read on for our favorite ways to sync Google Calendar with Outlook.

Why Should You Sync Microsoft Outlook With Google Calendar?

Keeping two different calendars will often be a logistical problem. Some situations make doing so necessary, though:

  • You work in two jobs that use either one of the calendars.
  • The two calendars might serve two different purposes—perhaps one is a personal calendar, and the other is for work.
  • You travel a lot and trust Microsoft Outlook Calendar on your desktop more than Google Calendar on your desktop (although Google Calendar can work offline, too).
  • You're using Google Calendar for collaboration on a special task and would like to see the same information in Microsoft Outlook.

Consider that, in your busy life, you would want to see both your calendars and keep them in sync. If you miss the official, bygone Google plug-in, you can use these alternatives to sync Outlook to Google Calendar.

The Best Tools to Sync Google Calendar With Outlook

Our criteria for a top pick: tools that not only sync Outlook Calendar to Google Calendar, but that also keep Microsoft Outlook and Calendar organized. We want something that boosts our productivity in Outlook and Google, bringing both worlds closer together.

1. Calendar Sync for Outlook and Google Calendar (Free, Paid)

The Calendar Sync options menu.

Calendar Sync 4.1 can help you set up one-way sync with either Microsoft Outlook or Google as the master. The free version does limit you to sync appointments and events within the last thirty days, but it's still worth trying.

The Pro version lets you two-way sync Google Calendar with Outlook; you can even use custom date ranges. The freedom to use multiple calendars and extra profiles are two other benefits of paying for the service. Both the free and Pro versions are available as portable versions, as well.

Key Features:

  • Choose one calendar to sync.
  • Sync Outlook Categories/Colors to Google Calendar.
  • One-way Outlook to Google Calendar sync includes deletions of duplicate events.
  • Auto-sync, sync on schedule, and sync with custom date ranges.
  • Match Outlook Reminder to a pop-up reminder in Google with sync.
  • Automate the sync in the background for every five minutes or at any custom time.
  • Supports Google two-step authentication, when enabled.
  • Sync events and mark them as Private.

2. Outlook Google Calendar Sync (Free)

Outlook Google Calendar Sync.

Outlook Google Calendar Sync 2.9.1 is completely free and supports two-way Outlook to Google sync. You can download it as an installer or as a portable app. The sync tool works with all versions of Microsoft Outlook, from 2003 to 2016 64-bit and Microsoft 365.

You can carry all event attributes from one calendar to the other. Events can be merged with existing ones into one calendar. Also, get a prompt before the tool deletes a duplicate event.

This calendar sync tool is the best alternative for privacy mavens out there. Events can be flagged as private; even the words in a subject line can be masked if you have security concerns. You can also make it work behind a web proxy, just in case.

Key Features:

  • Select the event attributes to sync.
  • Configure the frequency of syncing calendar updates.
  • Set custom date ranges to cover all past and future events.
  • Sync the default calendar or choose from the other non-default Outlook calendars.
  • Full CSV exports of calendars are supported.
  • Syncs recurring items properly as a series.

3. G Suite Sync for Microsoft Outlook (Google Apps Users)

If you're part of a larger collaborative team, G Suite is a great cloud productivity tool. The suite includes Gmail, Docs, Drive, and Calendar; the business software also gives you interoperability with Microsoft Outlook and additional security options like two-step authentication and SSO.

Previously called Google Apps Sync for Microsoft Outlook, G Suite Sync for Microsoft Outlook is the gangplank between both tools. A detailed comparison between both calendars is available on the G Suite support page.

Key Features:

  • Outlook-Google Calendar sync for multiple calendars.
  • Include events, reminders, descriptions, attendees, and locations with your Google-Outlook Calendar sync.
  • Sync Google Calendar to Outlook accounts of other users.
  • Free or busy status is kept intact across both calendars.

4. Microsoft Power Automate

Microsoft Power Automate was designed to create automated workflows that connect two or more online services together.

Right now, there are more than 300 connectors that you can utilize. One of them is a bridge that allows you to sync Outlook with Google Calendar. There are also other dedicated connectors for Outlook 365 and Outlook.com, as well.

Smartphone Apps to Sync Outlook With Google Calendar

You can also use each company's official app to sync Outlook and Google Calendar; it's the simplest solution when you're on the move. We have a couple that we can recommend.

1. Use Both Calendar Mobile Apps

Microsoft Outlook and Google Calendar both have apps for Android and iOS. Installing these apps is an easy and quick solution, and with timely notifications and smart scheduling, you can configure both calendars for specific events.

After Microsoft introduced shared calendar support to its Outlook client, things got a lot easier. Now, your contacts can get access to specific Microsoft Outlook calendars, too.
