- -Email IDs: The
idfield shows the last 20 characters of the full message ID. Use this ID with commands likeread,mark-read,delete, etc. - -Numbered results: Emails are numbered (n: 1, 2, 3...) for easy reference in conversation.
- -Text extraction: HTML email bodies are automatically converted to plain text.
- -Token expiry: Access tokens expire after ~1 hour. Run
outlook-token.sh refreshwhen you see auth errors. - -Recent emails: Commands like
read,mark-read, etc. search the 100 most recent emails for the ID.
Troubleshooting
"Token expired" → Runoutlook-token.sh refresh
"Invalid grant" → Token invalid, re-run setup: outlook-setup.sh
"Insufficient privileges" → Check app permissions in Azure Portal → API Permissions
"Message not found" → The email may be older than 100 messages. Use search to find it first.
"Folder not found" → Use exact folder name. Run folders to see available folders.
