Microsoft 365 Mail

Manage Outlook emails with full inbox control, attachment handling, and shared mailbox support

Overview

The Microsoft 365 Mail server enables AI assistants to interact with Microsoft Outlook and Exchange Online, providing comprehensive email management, attachment handling, and shared mailbox capabilities through Microsoft Graph API.

How to Add Microsoft 365 Mail

The setup process varies depending on your Microsoft account type:

Personal Outlook Users

If you have a free outlook.com email address:

1. Add Server

   Add the Microsoft 365 Mail server to your Nexus environment through the server directory.

2. Authorize

   Simply log in and approve the OAuth consent request. No additional steps needed.

   
3. Test Connection

   Try “Show me my latest 5 emails” to verify the connection works.

Microsoft 365 Business Users

For Microsoft 365 Business or Office 365 license holders, setup is straightforward:

1. Add Server

   Add the Microsoft 365 Mail server to your Nexus environment through the server directory.

2. Authorize

   Simply log in and approve the OAuth consent request. No admin approval needed for Mail.

   
3. Test Connection

   Try “Show me my latest 5 emails” to verify the connection works.

Admin approval is NOT required for Mail. Unlike other Microsoft 365 apps (SharePoint, Teams, etc.), the Mail server works with direct user consent for both personal and business accounts.
