How to sync work and personal calendars without colleagues seeing your personal events

Most people who sell or do client work end up with two calendars. The work one is on a company Google Workspace or Microsoft 365 account. The personal one is on a free Gmail or Outlook.com account, with family events, the gym and the dentist.

Each calendar only knows its own events. So when a client books through your work calendar, or a colleague looks for a free slot, your personal commitments don't exist. You find out when two things land at once.

Syncing doesn't have to mean merging. You want the work calendar to know when you're busy, and you want to see both in one place. You usually don't want colleagues reading the details of your personal life.

Your work account is run by your company's admin, and they decide what you can share. Google's help page on sharing says: "If your calendar is for your work or school, your administrator decides if you can share it." It also warns that an admin can see your calendar's event details even if you don't share it.

So before you start, check whether sharing out of your work account is allowed. If it's blocked, go the other way and bring your personal calendar into your work account, which is usually allowed.

This is the safest option and works well in Google Calendar. You share your personal calendar with your work account, set to show only when you're busy.

From Google's help page, on a computer:

1. Open Google Calendar with your personal account.
2. Under My calendars, to the right of your calendar, click More, then Settings and sharing.
3. Under Shared with, click Add people and groups, and add your work email address.
4. Choose "See only free/busy (hide details)" and click Send.
5. In your work account, open the email and click the link to add the calendar.

Google's page says free/busy means people "can only find out when you're busy" and "can't find the names or details about events". Your work calendar then shows a busy block for the school play, with no title.

If your work runs on Microsoft 365, Outlook on the web has this built in. Microsoft's help page says you can connect one Outlook.com or Google account to your work or school account.

1. Sign in to your work account in Outlook on the web and go to Calendar.
2. Select Add calendar, then Add personal calendars.
3. Choose your personal account and sign in to it.

Microsoft says your personal events then count towards your availability, and that in the Scheduling Assistant they show only as "Tentative, Busy, or Away", without the title. You can also create personal events from your work calendar without switching accounts. Adding the calendar doesn't bring in your personal email.

If neither of those is possible, most calendar apps can show another calendar from a link. Google calls this the Secret address in iCal format.

From Google's page on syncing with other programs:

1. Open Google Calendar and click Settings.
2. Under Settings for my calendars, click the calendar you want.
3. Click Integrate calendar and copy the "Secret address in iCal format".
4. Paste it into your other calendar app as a calendar from a URL.

Google calls this a read-only view, so you can see your personal events but not edit them from the other app. It also says only you should know this address, and to click Reset if you share it by mistake. Anyone with the link can see every detail, so treat it like a password.

For most people, the first two are the answer. Use the iCal link only when sharing is blocked.

If you sell, add one more habit: put your selling time on the calendar as well, not just meetings. A calling block with a name on it is far harder to book over. Sales productivity tips covers how to protect one, and the daily planner puts your calls and follow-ups beside the meetings.

1. Check whether your company lets you share your work calendar, or add one to it.
2. Pick one way from the table above. Don't set up two, or you'll see everything twice.
3. Set the personal calendar to free/busy wherever colleagues can see it.
4. Add your regular personal commitments, like school runs and training, so the busy blocks are real.
5. Block your selling time on the work calendar, with a name.
