Learning how to enable the two-way sync on Google Calendar and Outlook 365 can help you do that!
Keep all your notes synced all the time. It doesn’t matter which device you are on. Just put a note on the calendar, and CompanionLink will facilitate the process of syncing the two different platforms and service provides. This flagship tool works as a bridge and provides you with the ultimate leisure of real-time syncing.
Why Two-Way Sync Matters
Two-way sync is essential. If you change something in Google Calendar, it will change in Outlook 365, too. This is important for people who work on different devices and helps for both personal and work accounts. With CompanionLink, you do not have to manage two calendars. Your meetings, tasks, and events will stay in sync.

Step 1: Download and Install CompanionLink
First, you need to download and install CompanionLink on your computer. You can find it on the CompanionLink website. Choose the correct version for your computer and install it like other applications. When installation is done, you will see the configuration wizard.
Step 2: Select Microsoft Outlook as Your Data Source
After you open the CompanionLink setup wizard:
- In the “Sync From” section, you select Microsoft Outlook.
- Choose the correct Outlook profile if you have more than one.
- Decide what you want to sync: Calendar, Contacts, Tasks, or Notes.
CompanionLink works with Microsoft 365, Outlook 2021, Outlook 2019, and older versions. The Sync Google Calendar with Outlook Guide provides more information.
Step 3: Configure Google as the Sync Destination
Now, you connect your Google account:
- In the “Sync To” section, select Google.
- Click the “Settings” button to log into your Google account.
- You must sign in and let CompanionLink access your Google Calendar data.
This connection is safe and hidden. After you finish the authorization, CompanionLink connects with your primary Google Calendar.
Step 4: Choose Two-Way Sync Mode
CompanionLink has many sync modes. You want two-way sync for calendar matching. Here is how you do it:
- In the settings panel, pick “Two-Way Sync” under Sync Direction.
- This lets updates from Google show in Outlook and the other way too.
- You can enable Auto-Sync and set times (every 15 minutes, hourly, or others).

Step 5: Customize Advanced Settings
Before you start your first sync, look at CompanionLink’s advanced options:
- Conflict Resolution: Deciding which calendar wins when both changes occur is essential.
- Category Mapping: You can match colors and categories between Outlook and Google.
- Field Matching: Sync special data fields for appointments or events.
- Deleted Item Handling: You must set rules for deletions.
If you sync more than calendars, like contacts or tasks, look at all tabs. For more details, see the Outlook and Google Setup Guide.
Step 6: Start the First Sync
After you finish the settings, click the “Sync Now” button on the CompanionLink interface. The software does these things:
- It pulls all calendar entries that are in Google and Outlook.
- Matches them using metadata like title, time, and attendees.
- It merges them into a synced view.
It’s a good idea to watch the first sync for duplicates or mistakes. CompanionLink gives log views for easy fixing.

Step 7: Check Sync on Both Ends
Now open:
- Google Calendar: You log in to your browser or app.
- Outlook 365: You open your desktop or web client.
Check if all appointments and events show up on both platforms. Add a test event to one calendar and check if it syncs with the other within your set time.

If you manage many calendars or sync different devices, CompanionLink helps you. You can map Outlook folders to Google calendars. You can also create calendar filters.
