Google Chat Introduces Interoperability with Slack and Microsoft Teams

Google is partnering with Mio to improve and streamline communication across different platforms, addressing the challenges of using multiple chat tools.

This is a small change for Google, but it makes a big difference for Outlook users who often work with Google Calendar users. This way, they can be the ones who organize the meetings when they send invitations.
The feature is currently being rolled out and is expected to be available to all Google Calendar users in approximately two weeks. It's worth noting that administrators don't need to take any action to activate this feature, as it will be updated automatically.
