If you are reading this article, most probably you are looking for a ways to be able to combine meetings of two or more calendars to give you the full visibility and simplify your day-to-day scheduling activities. Let's discuss what are the possible solutions to this problem for Google and Outlook calendars, and how SyncPenguin can help you.

Sharing vs Syncing

Most of the scheduling and digital calendar services allow users to share their calendar with other users or third-party applications. This gives you the ability to see meetings (and in some cases even edit them), but there are certain drawbacks to this method. Let's compare calendar sharing and syncing.

Sharing

If you share your calendar with another account, the result of this is that you now see two separate calendars that don't interact with each other in any way. Your primary calendar remains the same, and if someone wants to schedule a meeting with you, they won't see your booked slots from the shared calendar. While this is a good way for you to be able to see your combined schedule, it does not help in any way when interacting with others.

Syncing (merging) calendars

Syncing (also called merging) two calendars is a way of combining information from both calendars into each other, after which you have full visibility of your schedule in both. If another person in your organization decides to invite you to a meeting, they will see your combined schedule and full availability across both of your calendars, which reduces the chance of you getting double-booked. This is the most reliable and robust way of maintaining two or more calendars while avoiding unnecessary headache.

How to sync calendars?

SyncPenguin can help you keep meetings of Google and Outlook calendars in sync or merged. We ensure that all of your appointments and bookings are in sync between the calendars, your colleagues can see your full availability and schedule, and you never again get double-booked because of missing information.

The Outlook connector can be used to sync calendars of current and legacy Microsoft accounts including:

  • Outlook.com personal accounts
  • Microsoft 365 corporate accounts (formerly known as Office 365)
  • Work or school accounts
  • Hotmail, Skype, or MSN accounts

With SyncPenguin you can:

  • Sync existing and future meetings, including recurring.
  • Merge two calendars.
  • Keep meetings synced in real-time.
  • Add filters or custom rules to the sync.
  • Adjust field mapping between the meetings.

This guide explains in detail how to create, configure and start such a sync.

If you'd like to start syncing right away, feel free to create an account and set up the sync on your own. Go back to the guide in case of any ambiguity or questions. You can also contact us for any questions, requests, or feedback.

Step 2. Create the sync

The next step is to create a sync in the Synchronizations section of the dashboard by clicking the + New sync button. You'll see a wizard page, where you have to do the following three steps:

  • Choose Google Calendar Meetings for the first app.
  • Then choose Personal Outlook Calendar Meetings for the second app.
  • Then select syncing direction.
  • Then click the Create button.

Step 3. Provide access to Google and Outlook calendars

Now that your sync is created, the next important step is to grant SyncPenguin access to your calendar meeting data. You'll see two Account sections for both apps involved in the sync. Below we explain how to connect and configure accounts.

How to connect Google?

The Google Calendar Meetings account connection section will look like this:

Please make sure both apps are properly connected before starting the sync.

DATA SECURITY

If you're concerned about the security of your private data, please check out the Security Practices page.

Step 4. Sync settings

In the Sync settings section you have the ability to adjust some of the default properties of your integration flow:

  • The name of your sync.
  • Sync direction (two-way or one-way).
  • Sync interval (by default the sync is triggered every 10 minutes).

Additionally, in Field mappings & rules you can customize the way data is mapped between the calendar apps, or add some filters or custom rules to the sync behavior. This is done using our simple no-code visual interface, which allows you to do both simple adjustments as well as implement complex custom scenarios.

You can learn more about our customization interface here.

Note that each sync has a Default mapping which includes all of the commons fields we know about between Google and Outlook calendar meetings. Additionally, we provide Only busy status mappings (both two-way and one-way) that will exclude any meeting information from being synced. This is useful in scenarios when you just need to sync your availability information and free/busy status to an external calendar without actually syncing any meeting details.

Step 5. Start syncing

The last step is to start the sync. To do that, click the Start syncing button.

You'll then be prompted with the following options:

  1. Only sync new data, meaning anything that will be added or updated starting from now.
  2. Merge all historic data two-way: take all meetings (from not more than a month ago by default) and merge them two-way. Any meetings that already exist on both calendars should be merged instead of creating duplicates.
  3. Merge all meetings in one direction only.
  4. Merge all meetings in the opposite direction.
Start sync
We'll be checking every 10 minutes for changes in your data.
What should we do initially with already existing meetings?

Once you make your choice, just click Start syncing. In case you decide to do the initial merge, it'll be instantly queued. Once it's done, we'll be checking for data changes every now and then (depending on the sync interval specified) and syncing accordingly. Each sync execution can be seen in the Sync history at the bottom of the sync page.
