An admin uploads the Microsoft 365 zip, you message Lexi in Teams, then the admin chooses **Enable Teams chat channel**. Microsoft Teams is Live in LeadLex. Lexi becomes a bot in Teams that you can ask about contacts, deals, tasks and meetings. In the app the card is called **Microsoft 365**, because the same download adds the LeadLex pane to Outlook. Only workspace admins can enable or disable the Teams chat channel.

## Install and enable

1. Open **Settings → Integrations** and select **Microsoft 365**.
2. Download **leadlex-m365-app.zip**.
3. Install the zip, either for the whole firm or just for yourself.
   - Whole firm: your Microsoft 365 admin opens **Admin center → Settings → Integrated apps → Upload custom app**, sets **App type** to **Teams app**, uploads the zip and assigns users. Do not choose **Office Add-in**, which accepts only XML and refuses the zip.
   - Just you: open Teams, go to **Apps → Manage your apps → Upload a custom app** and choose the zip.
4. Send Lexi a message in Teams. LeadLex detects your workspace. Until you do, **Settings → Notifications** shows **Say hi to the bot to enable** for Teams.
5. Back in Settings, choose **Enable Teams chat channel**. A confirmation says "Teams enabled. Send Lexi a message to complete setup."

## Notification choices

The first time a chat channel connects, LeadLex asks which notifications you want there. Every box starts unticked. Nothing is sent to the channel until you tick something.

## Switch it off

Choose **Disconnect Teams chat channel**. This stops the chat channel only. Installed Outlook panes keep working.

## What happens next

Ask Lexi anything you would ask in the app, such as "What is open with Nordlicht GmbH?" See [Lexi prompt tips](/help/lexi-and-channels/lexi-prompt-tips).
