You can use the Commvault software to back up and restore Microsoft Exchange Online.


Data You Can Back Up

  • Content

    • Emails

    • Calendars

    • Contacts

    • Conversations

  • Mailboxes

    • Primary mailboxes

    • Archive mailboxes

    • Group mailboxes

    • Shared mailboxes

    • Public folder mailboxes

    • Team mailboxes

Backups You Can Perform

  • Forever incremental backups

When You Can Perform Backups

  • On a schedule: The server plan that you assign manages scheduled backups

  • On demand: You can perform on-demand backups at any time


Backups You Can Use for Restores

  • The most recent backup: For example, restore the most recent backup to its original location

  • A backup from a specific date: For example, restore data to a point in time before it became unusable

  • Backups from a date range: For example, restore data that was accidentally deleted

Destinations You Can Restore To

  • The current location (in place)

  • A different folder on the same mailbox, or a different Exchange mailbox (out of place)

  • A CAB, EML, or PST file

  • A disk


You can use either basic or modern authentication to access data for backups and restores.


Data is retained according to the Office 365 plan that you assign to a mailbox when you add it to the Exchange Online app in Commvault. The default value for data retention is indefinite. You can modify that value to limit the amount of time that data is retained.

The index server is scanned every 24 hours. Messages that are eligible for data aging based on their received time and the rules defined in the plans are pruned.
