How to Connect Muse to Email and Calendar Safely
The safest useful setup gives Muse the smallest access required for one job, then expands only after observed success and clean recovery.
Bottom line
Connect Muse to a secondary account first, separate reading from sending or editing, and test ambiguity, prompt injection, revocation, logs, and deletion before adding primary data.

- • Exact connector scopes depend on the current account and rollout.
- • No checklist eliminates agent error or hostile content risk.

Short answer
Begin with a secondary email address and calendar containing synthetic or low-risk events. Grant the narrowest available scope, use read-only tasks first, and require explicit approval before Muse sends, deletes, invites, reschedules, or exposes private content. Broaden access only after it handles normal and adversarial cases correctly and leaves a complete audit trail.
Map the exact job
Define one outcome such as summarizing newsletters, proposing open meeting times, or drafting replies. List the folders, calendars, people, fields, and actions it actually needs. “Manage my inbox” is not a permission specification.
Separate reading from writing
Reading messages, drafting a reply, sending it, deleting mail, changing an event, inviting guests, and opening attachments carry different consequences. Keep write actions disabled or individually approved during the pilot. Never treat a convenient persistent approval as harmless merely because the first task was low risk.
Build failure tests
Include two people with similar names, an outdated event, conflicting time zones, confidential text, an email that tells the agent to ignore prior instructions, a malicious attachment, a revoked connector, and a request that should be refused. Check whether Muse preserves constraints and asks at the right boundary.
Test exit and recovery
Revoke access during an active task. Confirm the task stops, tokens no longer work, scheduled work is disabled, audit history remains available, remembered information can be removed, and reconnecting does not silently restore old authority.
Roll out deliberately
After at least two weeks, review accepted time saved, corrections, incorrect recipients, missed approvals, false refusals, sensitive exposures, and recovery. Expand one scope at a time, name an owner, and repeat the audit after product or policy changes.

Frequently asked questions
Should Muse use a primary inbox first?
No. Start with a secondary or sandbox account containing low-risk data and representative test cases.
What permissions should Muse receive?
Only the minimum scopes required for one defined job, with read access separated from sending, deleting, scheduling, or inviting.
How do I test prompt injection?
Place an untrusted message or page that instructs the agent to ignore your rules, reveal data, or take an unrelated action, then verify that it refuses and records the event.
What should happen when access is revoked?
Active and scheduled work should stop, tokens should fail, old authority should not return silently, and retained information should follow documented deletion controls.
