How to Configure Microsoft Exchange Online Email Import

An Office 365 Exchange Online service account provides Exchange Server directory permissions to grant the Barracuda Cloud Archiving Service read access to all mailboxes.

Use the steps in this article to import email from Exchange Online, that meets the specified criteria, to the Barracuda Cloud Archiving Service. Use autodiscover to automatically populate your Exchange settings using the steps in the section Automatically Discover Settings. If, however, autodiscover is unable to identify your Exchange settings, you can manually enter the details as described in the section Manually Configure Settings.

Requirements

• Microsoft .NET Framework 4.5 or 4.5.1 and either the Windows Management Framework 3.0 or the Windows Management Framework 4.0

• Verify the service account has the following:

  • A mailbox that is not hidden in the Global Address list.

  • A license that supports Outlook (i.e., not a kiosk license).

• Enable RPC over HTTP (RoH) for the mailbox. See also How to Enable RPC over HTTP Connectivity.

Step 1. Connect to Office 365 Exchange Online

1. Open Windows PowerShell, enter the following command, and then press Enter:
   $UserCredential = Get-Credential
2. In the Windows PowerShell Credential Request dialog box, enter your Exchange Online user name and password, and then click OK.

3. Enter the following command, and then press Enter:
   $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

   For more information, refer to the Microsoft TechNet article Connect to Exchange Online using remote PowerShell.

4. Enter the following command, and then press Enter:
   Import-PSSession $Session

5. Enter the following command, and then press Enter:
   Get-Mailbox -ResultSize unlimited | Add-MailboxPermission -User ServiceAccount@domain.com -AccessRights fullaccess -InheritanceType all -Automapping $false

   Permissions are assigned on existing mailboxes only; if additional mailboxes are added to your organization, you must rerun this command.

   For more information on adding mailbox permissions, see Add-MailboxPermission in Microsoft TechNet. For information on testing mailbox rights, see Get-MailboxPermission in Microsoft TechNet.
