Does outlook_diagnose change my email accounts?

No. It's a read-only diagnostic. It only reads which accounts Outlook and Mail.app have configured and reports the comparison — it never adds, removes, sends, or modifies anything.

Why compare Outlook with Mail.app?

Many Mac users keep some accounts in Outlook and others in Apple Mail. Comparing the two reveals accounts that exist in one app but are missing from the other, which is the most common reason email seems to be 'missing' on your Mac.

Is my email data sent to the cloud?

No. LMCP runs entirely on your Mac. The tool inspects your local account configuration and returns it to your AI session. Nothing is uploaded or stored on any LMCP server, and there are no API keys involved.

Diagnose Outlook Email Accounts on Mac with AI

What outlook_diagnose does

The outlook_diagnose tool inspects your Mac to see which email accounts are configured inside Microsoft Outlook and compares them against the accounts set up in Apple Mail (Mail.app). It's a read-only health check: it never sends, deletes, or changes anything. You get a clear picture of which mailboxes each app knows about, so you can spot accounts that exist in one place but not the other.

A typical prompt you'd type to your AI assistant: "Check which email accounts I have in Outlook and tell me if any are missing from Mail." The AI runs outlook_diagnose and reports back the configured Outlook accounts, the Mail.app accounts, and the differences between the two.

Automation

Diagnostics shine when chained with other tools. After outlook_diagnose surfaces your configured accounts, the AI can move straight into action: list unread mail across both apps, search a specific Outlook mailbox, or draft a reply from the right sender. For example: "Diagnose my Outlook accounts, then show me unread messages from my work account." The AI uses the diagnosis to pick the correct mailbox before reading or composing — no guessing, no wrong-account mistakes.

Context

Because LMCP runs on your Mac and talks to your real apps, the AI works with your actual Outlook and Mail.app setup — not a generic example or a stale import. It sees the genuine list of accounts as they're configured right now. That real-world context means the answers are accurate to your machine, and any follow-up actions land in the correct mailbox.

Productivity

Manually checking account parity between Outlook and Mail means opening both apps, digging through Settings or Preferences, and eyeballing two lists. outlook_diagnose collapses that into a single sentence. When email "isn't showing up," the first question is usually "is the account even configured here?" — this tool answers it instantly, saving the back-and-forth of troubleshooting a missing inbox. It's the fast first step before any email automation, so the AI always knows what mailboxes it's working with.

Privacy & GDPR

Everything runs locally on your Mac. The diagnosis reads your account configuration on-device and returns it to your AI session — no copy is uploaded to an LMCP server, and nothing is stored in the cloud. There are no API keys to manage and no third-party mailbox access. This local-only design makes LMCP GDPR-compliant by architecture: your email data never leaves your computer.
