description

Microsoft 365 spam folder manager for Outlook/Exchange mailboxes. Automatically analyzes junk/spam emails, calculates a suspicious score based on structural patterns (missing unsubscribe links, poor language, suspicious domains, wrong character sets, etc.), and helps clean up the junk folder. Supports review mode (default) where user approves each action, and automatic mode for batch processing. Works with shared mailboxes via --mailbox flag. Related keywords: Outlook, Exchange Online, spam filter, junk email, phishing, email security. **Token cost:** ~500-1.5k tokens per use.

Usage

Review mode (default) — user must approve each action

# Analyze junk folder and show suspicious scores (review mode - default)
node skills/m365-spam-manager/scripts/analyze.mjs --profile tom-business-mail --mailbox [e-mail]

# Move a false positive to inbox (requires confirmation)
node skills/m365-spam-manager/scripts/move-to-inbox.mjs --profile tom-business-mail --mailbox [e-mail] --id <MSG_ID>

# Move confirmed spam to learning folder
node skills/m365-spam-manager/scripts/move-to-learning.mjs --profile tom-business-mail --mailbox [e-mail] --id <MSG_ID>

Automatic mode (no confirmation)

# Auto-clean: move high-confidence spam to learning, medium to review
node skills/m365-spam-manager/scripts/auto-clean.mjs --profile tom-business-mail --mailbox [e-mail] --threshold 80

Suspicious Score Calculation

The analyzer calculates a score (0-100) based on:

Pattern	Points	Description
No unsubscribe link	+20	Legitimate marketing must have one
Suspicious sender domain	+15	Free email, misspellings, random strings
All caps subject	+10	Spam often shouts
Excessive punctuation	+10	!!!, ???, $$$
Suspicious keywords	+15	crypto, win, free, urgent, verify, bank, password, ...
Mismatched language	+10	Subject in DE, body EN or vice versa
Known scam patterns	+25	"Attention - suspected SPAM", fake invoices
Free email provider	+10	gmail, yahoo, hotmail in From (not Reply-To)
No DKIM/SPF indication	+5	Graph doesn't show auth results

Score thresholds

• 0-30: Low suspicion — likely legitimate
• 31-70: Medium — review recommended
• 71-100: High — almost certainly spam

Policy

This skill respects the same policy as m365-mailbox:

• read: autonomous (analyze, list)
• move: controlled (move to inbox/learning folder)

In review mode, the script always prompts for confirmation before moving emails.
