How to Backup and
Restore Microsoft 365 Calendar Securely

Accidental deletions, sync errors, and retention policies can quickly make your calendar data inaccessible or permanently lost. Relying solely on Microsoft’s native recovery tools puts your important schedules and appointments at risk.

BackupVault’s Microsoft 365 backup ensures your calendar data is fully protected, securely stored, and easily recoverable, giving you true peace of mind.

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.

The limitations of Microsoft 365 & the Shared Responsibility Model

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.
