How to Connect Muse to Email and Calendar Safely

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Include two people with similar names, an outdated event, conflicting time zones, confidential text, an email that tells the agent to ignore prior instructions, a malicious attachment, a revoked connector, and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.
