How to Share Only Busy Time Across Work and Personal Calendars

Sharing only busy time means communicating when you are unavailable without sending the appointment's personal details. You can do that with native free/busy permissions, a manual generic event, or an automatically maintained busy copy. Choose according to whether someone needs to view your calendar or another calendar needs its own block.

A colleague arranging a meeting usually needs to know that Tuesday at ten is unavailable. They rarely need to know the name of the appointment, its address, or what you wrote in the notes.

Decide who needs the information

If another person only needs to inspect your schedule, restricted sharing may be enough. In Google Calendar on a computer, open the calendar's sharing settings, add the person's address and choose the free/busy permission offered for that calendar. Work and school administrators can limit sharing. Google explains calendar permission levels.

In Outlook, review the calendar's sharing permissions and select the lowest suitable availability level. Exact names vary with the account and app version. This grants a view of the original calendar rather than creating events in the recipient's calendar.

For a partner planning around your workday, that may be ideal. For a work scheduling system that checks only your main work calendar, you may need a different approach.

Use manual busy blocks for occasional appointments

Create an event in the destination calendar with the same occupied time, a neutral title and busy availability. Leave out location, description and guests.

Manual blocks are easy to create, but you have to maintain them. Move the block when the appointment changes and remove it when the appointment is canceled. Frequent changes make that extra task easier to miss.

Private visibility limits some viewers' access; removing the details keeps them out of the work copy altogether.

Native personal-availability options

Outlook on the web can connect one personal Google or Outlook.com account and include its primary calendar in work availability. Scheduling Assistant shows the occupied time without personal details, making this a free option for that setup.

It does not cover every secondary calendar or provider. The Outlook work-calendar guide walks through the choices and limits.

For a booking page, check whether it can directly consider your source calendars. Selecting them there may remove the need to copy events at all. That helps the booking page, though it does not automatically alter what coworkers see elsewhere.

Review all the fields in an automatic copy

When using a sync service or approved automation, check more than the title. Consider:

Description and notes, including pasted messages.
Location, including addresses and video-call links.
Guests and organizer information.
Availability and visibility settings.
Reminders that may appear on shared devices.

Choose what the destination actually needs. A generic title plus occupied time is often enough. Do not add personal source names as prefixes if those names themselves disclose something sensitive.

Also decide which events should copy. A reminder marked Free and a canceled invitation may not need a work block. Working-hour filters can be useful when evening commitments do not affect the destination audience.

Set up busy copies in Avum

Connect the personal and work accounts, then create a Sync Rule into the work calendar used for scheduling. Replace the title with “Busy,” omit descriptions and locations, and set copied events to Busy. Review the destination visibility setting alongside its existing sharing permissions.

Avum supports Google, Outlook/Microsoft 365, iCloud, and CalDAV connections, plus read-only ICS sources. For a CalDAV destination, the connected account needs write access and Avum must complete write verification. Keep editing appointments in their original calendar.

For example, an appointment can remain fully described in iCloud while its Outlook copy occupies 10 to 11 a.m. Avum updates the copy when the original changes. If a native feature already gives you the private availability signal you need, you can use that instead.

The destination viewer's access

Use a test event with sample details. Confirm the destination's times and generic title, then inspect the fields you excluded. Ask a coworker with the usual calendar permissions to check their view too; your owner view can reveal more than theirs.

Move the source and confirm the new time. Delete the test and check the destination again. Automatic processing can take time, so avoid making urgent plans depend on an unverified new rule.

Review the arrangement when your job, client, or sharing permissions change, and remove busy copies from calendars that no longer need them.
