Chat with guests from a Google Calendar event

Important: This feature is not available for personal Google Accounts (@gmail.com).

If you have a work or school account, you can chat with guests from a Google Calendar event.

When you chat with guests from an event, it opens a group conversation in Google Chat. This conversation:

• Includes all event guests in your organization, regardless of their RSVP status.
• Can have up to 200 guests. This also includes Google Groups in your organization, and their privacy settings are respected.

If you have a work account, the conversation:

• Sets the event organizer as the conversation owner.
• Matches the Calendar event title and date, and syncs in real time with changes that you make to the event.

If there are external Google Accounts, guests on other platforms like Outlook, and guests outside your organization on the event, they do not join the conversation.

Chat with guests

1. On your computer, open Google Calendar.
2. Click an event.
3. Next to the number of guests, click Chat with guests .

Turn chat messaging on or off before an event

1. On your computer, open Google Calendar.
2. Open an event.
3. At the top right, click Edit event .
4. Next to the Meet video link, click Video call options .
5. In the “Chat moderation” section, turn “Let contributors send messages” on or off.

Tip: If you turn chat messages off in recurring meetings or meetings that use the same meeting code, the setting is saved for the next scheduled meeting.

How a conversation is named

• The conversation title matches the Calendar event title and date (for example, "Sales Team Weekly - Nov 8").
• The date and language format in the title is based on the event organizer's language and timezone settings.
• The conversation appears in Google Chat, in the “Direct messages” section.

How your conversation syncs with the event

Any changes you make before the event starts automatically syncs with the conversation. For example:

• When you update the event title, it updates the name of the conversation.
• When you add or remove guests from the event, it also adds or removes them from the conversation.
• If you add or remove someone in Google Chat, the change is overridden by changes in the Calendar event.
  • For example, if you add someone to the conversation, they are removed if you remove them from the corresponding event.

In addition:

• The "Chat with guests" button on the Calendar event remains as a link for eligible guests to find the chat history.
• If a guest is removed from the chat they lose access to meeting conversation.
• If a removed guest joins the meeting, they will only have access to messages during the meeting, and messages disappear when the meeting ends.
• To restore full access, you must manually add them back to the chat.

Turn on “See guest list” for people invited to the Calendar event

As the event organizer, you control if people invited to your event can view the guest list. When you turn off “See guest list,” it affects how your conversation works.

If “See guest list” is:

• Off before the meeting conversation is created:
  • The "Chat with guests" button is not available in the Calendar event for anyone.
  • Guests can only chat during the meeting. They do not get a meeting conversation in Chat, and all messages disappear when the meeting ends.
• Off after the meeting conversation is created:
  • The "Chat with guests" button is not available in the Calendar event for anyone.
  • The chat conversation continues to exist in Google Chat for its current members.
  • However, the automatic sync between the Calendar guest list and the chat membership stops permanently.
  • Future changes to the Calendar guest list no longer update the chat membership.

1. On your computer, open Google Calendar.
2. Open an event.
3. At the top right, click Edit event .
4. On the right, click the Guests tab.
5. Under “Guest permissions,” turn on See guest list.
