Step 1 - Set Up Essentials for Office 365

  • Last updated on

Managed Service Providers (MSPs) : See Barracuda Essentials for MSPs  for information on getting started with ECHOplatform and activating Barracuda Essentials.

For each Barracuda Cloud Control account, you can have either a linked Barracuda Email Security Gateway appliance or a Barracuda Email Security Service subscription.
You cannot use a single Barracuda Cloud Control account for both a linked appliance and the service subscription.

This article assumes you are deploying Barracuda Services for the first time. If you previously deployed Barracuda Cloud-to-Cloud Backup, Barracuda Email Security Service, or the Barracuda Cloud Archiving Service and want to migrate to Barracuda Essentials for Office 365, contact your Barracuda Networks sales representative.

Complete All Steps
Be sure to complete all steps on this page that are required for the components in your plan. For example, if you have Barracuda Cloud Archiving Service, be sure to create the send connector, as described in Step 2 below.

Ensure Connectivity and Redundancy

The Barracuda Email Security Service connects with your network from various IP addresses, including performing LDAP lookups. To ensure that the service can connect with your network, allow traffic originating from the range of network addresses based on your Barracuda Email Security Service instance; see Barracuda Email Security Service IP Ranges.

Select Your Plan

Determine the plan that best suits your organization's needs. The available options are built on the following components:

  • Barracuda Email Security – Security service protecting both inbound and outbound email against the latest spam, viruses, worms, phishing and denial of service attacks.
  • Advanced Threat Protection – Protects against advanced malware, zero-day exploits, and targeted attacks.
  • Barracuda Cloud Archiving Service – Journal mail directly from Office 365 to the Barracuda Cloud to optimize email storage, meet regulatory compliance and e-discovery requirements, and provide anytime/anywhere access to old emails.
  • Barracuda Cloud-to-Cloud Backup – Protects Exchange Online, OneDrive for Business, and SharePoint Online data by backing it up directly to Barracuda Cloud Storage. For Exchange Online, Barracuda Cloud-to-Cloud Backup protects all email messages, including all attachments, as well as the complete folder structure of each user's mailbox. In OneDrive for Business, all files under the Documents Library, including the entire folder structure, are protected. Easily locate and restore folders, individual items, or entire mailboxes. Barracuda Cloud-to-Cloud Backup provides complete protection of SharePoint Online. With item-level recovery options, items can be restored directly into SharePoint Online from the backups of Document Libraries, Site Page Libraries, and Picture Libraries in Team Site, Publishing Site, and Wiki Site.
