Restoring Microsoft Exchange Online hosted for Office 365

  • This article is for Windows only

Any number of mailboxes can be selected for restore, including individual mailboxes. Mailbox contents can be restored to the original server, an alternate server, to a local Exchange server, or to disk. For all options except restore to disk, mailbox contents can be restored to a mailbox with the same name as the original or to an alternate mailbox with a different name.

Restores to disk can be done as .pst files (one for each mailbox) or as files (.eml, .png, etc) that correspond to each item within the mailboxes restored. For more information about restoring as files, please refer to How to Use Restored Files after an Exchange Mailbox Restore to Disk.

Restore Requirements

The following requirements must be met, whether restoring to the original computer or to an alternate computer:

  • The amandabackup / CarboniteUser user must have full access to the folder where the backups are stored.
    • For cloud backups, this is the chosen Download Folder.
    • For local backups, this is the folder where the backups are stored on the local disk.
  • Likewise, the amandabackup / CarboniteUser user must have full access to the folder(s) to which the backups are being restored.

Additional Restore Requirements

The following additional requirements must be met for Exchange Online Mailboxes:

  • An administrator account must be specified within CSSB. This user must have the Global Administrator role. The username must be in the User Principal Name (UPN) or email format, such as UserName@Domain. For example, Admin@company.com and username@company.onmicrosoft.com are both in the correct format.
    • The Exchange Impersonation right must be granted to this administrator account.
      • This right can be granted to an account from the Admin page in the Office 365 portal.
  • The Exchange Discovery Management role must be granted to this administrator account.
    • This role can be granted to an account from the Admin page in the Office 365 portal.
  • When restoring to a local Exchange server, a server URL must be specified. The system performing the restore must be able to reach and resolve the server URL.
  • When restoring to an Exchange Online account, the system performing the restore must be able to connect to the Office 365 account. Connectivity can be verified from any browser.
  • Restore to an Alternate Mailbox is allowed with three exceptions:
    • An alternate mailbox cannot be specified for restores to disk. The files will always restore to a folder with the same name as the original mailbox.
    • An alternate mailbox is not allowed when Restore All is selected, even if the backup contains just one mailbox.
    • An alternate mailbox is not allowed when more than one mailbox is chosen in Restore Select.
  • When restoring to .pst files, Microsoft Outlook must be installed on the system.

Please choose the scenario that best fits your situation.

Restoring to the Original Computer

If Carbonite Safe Server Backup is already installed on your computer, you can open the user interface and begin restoring your mailbox contents to your computer.

Restoring the Backup Data

To restore Exchange Online mailbox contents, please follow these steps:

  1. Navigate to the Restore page and select the backup run associated with the backup set you want to restore.
  2. In the Restore Point drop-down menu, CSSB will show you all the relevant backup images for this restore operation.
  3. After confirming your restore settings, click Restore Now to start the restore process.

Restoring to a Different Computer

You can restore your Exchange Online mailbox contents originating from one computer to a different computer. This method is mostly used to create a clone of the original system. It is recommended that you install the same Windows Operating System (with the same service packs) on the restore computer as was installed on the original computer. This procedure requires some additional steps before you can launch the actual restore process. The steps are as follows:
