Outlook integration for audit scheduling: what IT should check
What IT teams should check before connecting audit scheduling software to Microsoft 365 calendars: organisation-wide versus per-user sync, permissions, admin consent and what data moves.
Key takeaways
- Organisation-wide sync avoids every auditor connecting one by one.
- Application permissions need administrator consent.
- Agree which calendars are read and which are written.
- Busy time should feed availability; private details should not be exposed.
Decide between per-user sync, where each auditor connects their own calendar, and organisation-wide sync, where an administrator grants the application access once for the tenant. Check the Microsoft Graph permissions requested, who gives admin consent, which calendars are read or written, and how busy time affects availability. ScheduleAI by Checkfirst supports organisation-wide (tenant-level) Outlook sync, and Outlook time counts in utilisation.
