🚨 Outlook + N8N Integration Blocked by Admin & Mailbox Permission Issues

🚨 Outlook + N8N Integration Blocked by Admin & Mailbox Permission Issues – Need Help!

Hi everyone,

For the past few days, I’ve been trying to connect my client’s Outlook account to N8N in order to create drafts, send emails, retrieve categories, etc.

Here’s the situation:

I created an app in Azure, retrieved the Client ID, Tenant ID, and Client Secret, and connected it to N8N.
When trying to send a draft, I got an error saying I didn’t have the required permissions.
I then updated the API scopes and permissions (with ChatGPT’s help) to grant full access.

The issue is that the Outlook account is managed by an external company, and my client’s account is not an admin account. I was given access to an admin account and granted all necessary API permissions to the app.

However:

When I connect to N8N using the admin account (which also has mailbox access), it says the mailbox is invalid or not found when running the workflow.
When I try connecting directly with my client’s Outlook account, it says I need admin privileges to connect the mailbox to N8N.
From the admin account, I can’t figure out how to properly grant access to the client’s mailbox.

Has anyone experienced this kind of issue before? Any help would be greatly appreciated.
