How to Back Up Microsoft 365 Calendar (Step-by-Step)
Backing up your Microsoft 365 calendar manually can help protect your important events and appointments.
Here’s a simple guide to exporting your calendar data from Outlook and the Microsoft 365 portal.
Export from Microsoft Outlook:
- Open Outlook and switch to Calendar view.
- Go to File > Open & Export > Import/Export.
- Choose Export to a file, then select either CSV or Outlook Data File (.pst).
- Pick your calendar folder and save the exported file locally.
Export from Microsoft 365 Portal:
- Log in to Microsoft 365 and open Outlook Web App.
- Navigate to Settings > View all Outlook settings > Calendar > Shared calendars.
- Under Publish a calendar, select your calendar and set permissions.
- Click Publish and download the provided ICS file.
What manual backup covers:
- Your basic calendar events and appointments in portable formats.
What it doesn’t cover:
- Detailed metadata, including attendee responses or custom reminders.
- Full support for recurring event exceptions.
- Granular restoration of specific events or dates.
- Automatic updates: manual exports must be repeated regularly.
While manual exports offer some protection, a full automated backup solution ensures complete, reliable recovery and peace of mind.

Why Manual Backups Aren’t Enough
Microsoft’s native recovery and manual export options offer limited protection – no automated scheduling, no point-in-time recovery, and gaps in data coverage. For regulated sectors, these limitations risk compliance breaches and data loss.
Our automated, policy-driven backup solutions deliver:
- Set-and-forget daily backups without manual effort
- Precise point-in-time recovery for fast, accurate restores
- Long-term retention and audit trails to meet compliance requirements
With BackupVault, you get reliable, comprehensive protection designed to keep your data secure and compliant.
