Switching between your inbox, calendar, and chat app all day adds up to a lot of wasted context switching. This guide shows how to connect Microsoft Outlook to Slack so your meetings automatically update your Slack status, and how to install the companion Outlook add-in so you can forward emails straight into a channel. It's aimed at anyone tired of manually updating their status every time they join a call.

01Open the Slack App Directory

From your workspace, go to the tools panel and open the App section to search Slack's directory of official integrations.

02Add the Outlook Calendar app

Search for Outlook Calendar, click Add to Slack, and follow the prompt to begin connecting your account.

03Authenticate with your Microsoft 365 account

You'll be redirected to a Microsoft login screen where you sign in and approve the requested permissions to link your corporate email and calendar.

Inside the app's home tab in Slack, turn on status syncing so your presence automatically switches to 'In a meeting' whenever your Outlook calendar shows you're busy.
