Short Answer:

If a calendar says “this computer only” in the Outlook desktop app, then CalendarBridge cannot sync to or from that calendar.

If a calendar is accessible from Outlook on the Web (i.e., it is a Microsoft 365 calendar hosted in Exchange Online) or is accessible on Outlook.com, CalendarBridge can sync your Google Calendar to that calendar, and thus to the Outlook desktop app.

Longer Answer:

First, let’s clarify Microsoft’s confusing “Outlook” branding:

• There is “Outlook” the desktop application that you download and install on your computer.
• There is “Outlook.com,” which is a personal email & calendar service that hosts @outlook.com, @hotmail.com, @live.com, and @msn.com email address (i.e., it’s Microsoft’s version of Gmail).
• “Outlook on the Web” is a web application for accessing Microsoft 365 calendars which are hosted in Exchange online.

Outlook the desktop app allows having calendars that live only on your computer. Such calendars will typically say “This computer only”:

Those calendars live only on your computer and CalendarBridge cannot access them. To sync those calendars you will need software that installs and runs locally on your computer. One free one is CalDav Synchronizer (which CalendarBridge is not affiliated with in any way).

We got rid of the terminology “two-way” (or “2-way”) sync connections because it was causing confusion for pricing and functionality.
The identical behavior of our old “two-way” sync connection can be achieved by setting up two one-way sync connections.

Sync connections are “always on” and work based on push notifications. Changes on a source calendar should propagate to a destination calendar within a few minutes.

A sync connection is a one-way, always-on connection between a source calendar and a destination calendar. Updates to events on the source calendar propagate to event copies on the destination calendar within a few minutes.

The number of sync connections you need depends on how many calendars you want to sync.

To illustrate, here are two common configurations involving 3 calendars X, Y, and Z (these calendars may reside on 1, 2, or 3 Google/Microsoft accounts):

• Copying events from X to Y and from Z  to Y requires 2 sync connections (X->Y, Z->Y)
• Copying events from each of X, Y, and Z to each other of X, Y, and Z requires 6 sync connections (X->Y, X->Z, Y->X, Y->Z, Z->X, Z->Y).

Please note that CalendarBridge does not make copies of copies. For example, if you were to setup the following two sync connections: X -> Y and Y -> Z , events from X would not appear on Z. To get events from X to Z would require a third sync connection: X->Z.

This is currently the expected behavior. Event copies are not “live,” which means edits made to, and deletes of, event copies created by CalendarBridge do not propagate back to the source calendar. This is in order to guarantee the integrity of native events on your calendar.

Also, any edits made to event copies created by CalendarBridge may get overwritten by subsequent sync activity.

To replace “(copy”) with custom text (or no text at all, which is not recommended), you must be a paying user and you will need to edit any existing syncs. See the Setting up Calendar Syncing documentation for more details.

Edit A Sync

When you connect a Google or Microsoft account to CalendarBridge, we only request the bare minimum access/permissions needed for syncing calendars. This includes your basic profile information and the ability to read and write your calendars. We do not request access to your contacts, your email, your files, or anything else. Just basic profile info and calendars.  (To see the actual permissions requested see Connecting Google calendars and Connecting Microsoft calendars)

As for the calendar data to which we have access, the only thing we do with it is copy it between your accounts as instructed by your sync connections. We do not store or analyze any of it. Check out our terms of service to learn more.

CalendarBridge does not sell advertising, does not sell data, and does not even analyze your calendar data. (No “artificial intelligence” here — just real intelligence to make a dead simple and reliable service).

The only way we make money while maintaining this total privacy of your calendar data is subscription revenue.

Thus, after your 7-day free trial, a paid subscription is required to keep the service active.

You will need a group plan if:

1. You want to connect more than 4 accounts on the same domain. The basic, premium, and pro plans are limited to 4 connected calendar accounts from any single domain. There is no limit on the total number of connected accounts, but there can only be 4 connected accounts for any particular domain. So if you are a small business with 4 users that wants to make due with a single premium or pro account, you can do that. If you have 5 or more users, however, you will need a group account.

2. You want to manage CalendarBridge syncing or scheduling links on behalf of other users. On the Basic, Premium, or Pro plans, all account management is through the standard end-user interfaces shown in the getting started guide.  With a group plan, you get access to an organization admin portal a user who has administrator privileges on one or more servers/tenants can:

• provision CalendarBridge licenses to users on their servers/tenants,
• connect end users’ accounts to CalendarBridge
• create syncs on behalf of end users (requires administrator privileges on both servers/tenants)
• create scheduling links on behalf of end users

3. You want fine-grained control over sync connections involving your domain. The admin portal that comes with a group plan allows server/tenant administrators to set policies on which domains your users are allowed to sync with and what information they are allowed to sync.

Google calendar keeps declined events on your calendar, but has a setting to hide them:

CalendarBridge cannot see whether you have chosen to hide declined events. Thus, calendarbridge will sync declined events with at “Declined:” prefix prepended to the subject of the event. If you subsequently delete the declined event from the source calendar, the “Declined:” event copy will be deleted.
