How to Sync Your Slack Status With Google Calendar (and Outlook)
Install the Google Calendar app in Slack, connect your primary calendar, and turn on Status Sync. Slack then sets In a meeting for accepted events with other invitees and Out of Office for OOO or PTO events. Setup steps, the rules, Outlook, and why sync sometimes does nothing.
To sync your Slack status with Google Calendar, install the Google Calendar app in your Slack workspace, connect your Google account and your primary calendar, and turn on Status Sync in the app's settings. From then on, Slack sets your status to In a meeting when an accepted event with other invitees starts, and to Out of Office when an event's title contains OOO or PTO. The status clears when the event ends. Outlook users get the same through the Outlook Calendar app.
Calendar sync changes your status text only. It does not touch your green or grey dot, so an hour-long Zoom call still turns you grey after 10 minutes, with "In a meeting" next to it. If you want the dot to follow your working hours too, Slack Green keeps your presence active on the schedule you set, from the cloud, with nothing installed on your computer.
How to sync Slack status with Google Calendar
1. Install the app (once per workspace). Open the Google Calendar page in the Slack Marketplace, click Add to Slack, then Allow. If a coworker already installed it, skip this step. Some workspaces require admin approval for apps.
2. Connect your Google account. In Slack on desktop, click Agents & tools in the sidebar (older versions show Tools), select Apps, and open Google Calendar. On the app's Home tab, click Connect an account and follow the prompts.
3. Connect your calendar. On the Home tab, click Connect Calendar, choose your calendar under Accounts, and click Done. You can add several calendars for notifications, but status sync works only with your primary calendar.
4. Turn on Status Sync. On the Home tab, click Settings and switch status syncing on.
On mobile, tap Jump to, search for Google Calendar, and use the same Home tab and Settings.
How to sync Slack status with Outlook Calendar
- Install the Outlook Calendar app from the Slack Marketplace.
- Open it from Agents & tools, then Apps, and link your Microsoft account.
- Click Turn on to start status syncing.
Outlook sync sets In a meeting during meetings, and on Enterprise plans it can also set Slack's out of office status from your Outlook out of office events.
When the calendar sets your status, and when it does not
Slack's help center lists the rules for the Google Calendar app:
| Your event | Slack status |
|---|---|
| Accepted, with other invitees | In a meeting |
| Title contains OOO or PTO, and you are shown as busy | Out of Office |
| A focus block with nobody else invited | No change |
| Not accepted and not marked busy | No change |
| Overlaps another event | No change |
| You already set a status yourself | No change |
| On a secondary calendar | No change |
Two more details. The status never includes the meeting's name, so coworkers see "In a meeting" and nothing about what it is. And you can change or clear the synced status at any time.

Your status says "In a meeting", but your dot is grey
This is the gap calendar sync leaves open. During a Zoom or Google Meet call you give Slack no input, so after 10 minutes your dot goes grey. The status explains why, but many people read the grey dot first. Status and dot are separate systems, and the dot follows the rules in how long does Slack stay active.
To keep the dot green through meetings, Slack Green keeps your presence active during the working hours you set, so the calendar handles the text and the schedule handles the dot. Other methods are compared in how to keep Slack active.
