- Log you into Azure (device code flow)
- Create an App Registration automatically
- Configure API permissions (Mail.ReadWrite, Mail.Send, Calendars.ReadWrite)
- Guide you through authorization
- Save credentials (including tenant context) to
~/.outlook-mcp/

Token Refresh
Access tokens expire after ~1 hour. Refresh with:
./scripts/outlook-token.sh refresh
Files
~/.outlook-mcp/config.json- Tenant ID, client ID, and client secret~/.outlook-mcp/credentials.json- OAuth tokens (access + refresh)
Permissions
Mail.ReadWrite- Read and modify emailsMail.Send- Send emailsCalendars.ReadWrite- Read and modify calendar eventsoffline_access- Refresh tokens (stay logged in)User.Read- Basic profile info
Notes
- 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" → Run outlook-token.sh refresh
"Invalid grant" → Token invalid, re-run setup: outlook-setup.sh
"AADSTS50194" → App is single-tenant but endpoint used /common; use tenant-specific endpoint or re-run outlook-setup.sh
"AADSTS700025" → App is configured as public client; disable public client flow in App Registration Authentication settings
"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.
