How to turn off group calendar notifications to everyone when calendar events are scheduled that do not include any attendees, such as out of office items?

Hi @Brandy Lapthorne,

Thank you for posting your question in the Microsoft Q&A forum.

I can get your situation when important updates get buried under a flood of Out of Office posts. You’re not alone, this happens because of how the channel calendar works in Teams.

The Channel Calendar app automatically posts every event created in that shared calendar to the channel’s Posts and Activity feed, even if no attendees are invited. This design is meant to keep everyone informed, but for Out of Office or vacation entries, it can feel overwhelming.

Unfortunately, there’s no single “turn off Out of Office notifications” toggle, however, here are some ways that often help reduce or stop these notifications:

1/ Turn off automatic posts for channel calendar:

• Go to the Channel Calendar tab in your Team.
• Click the Settings (gear icon).
• Find Post to channel about events and toggle it off.

If you don’t see this option, your tenant may not have the latest update, you can check this with your IT admin.

2/ Mute channel notifications:

• In Teams, go to the channel > More options (…) > Channel notifications.
• Set All new posts to Off or Only show in feed.

This stops banner and pop-up notifications for these posts.

3/ Admin-level control:

If your organization wants to stop these posts globally:

• Remove the Channel Calendar app from the Team.
• Or adjust Teams App Setup Policy in the Admin Center to restrict posting behavior.

You can see: Manage app setup policies in Microsoft Teams

4/ Alternative tracking for Out of Office:

Instead of using the shared calendar for Out of Office, consider using:

• A dedicated Vacation Planner tab (Planner or Lists).
• Or a shared Excel file in the Team for availability.

5/ Submit feedback:

If none of these steps meet your needs, you can submit feedback or a feature request to Microsoft so the product team can consider adding a toggle for Out of Office notifications.

As a forum moderator, I hope you understand that I don’t have the ability to modify or escalate product issues directly. This is the most effective way to ensure your voice reaches the product team and can be considered for future improvements.

You can do this in Teams by selecting Help > Feedback, or through the Microsoft 365 Feedback Hub > Send Feedback > Describe your proposal in detail so the team can consider it for future improvements.
