Protecting Your Email in the Microsoft Cloud: Exchange Online Backup

Email is More Important Than Ever

The first email was sent in 1971. Today, close to 81% of the almost 205 billion emails sent each day are opened on mobile devices that contain computational power unimaginable to the original email senders. Technologies, platforms, devices, and so much more have risen and fallen from then to today, yet email remains mostly unchanged and is still mission critical across organizations and among consumers.












Email hasn’t undergone many revolutionary transformations, but small improvements here and there over time have extended its longevity. First, user experience improvements help the aging technology remain competitive in a world of persistent chat, enterprise social, and Instagram. Some good examples:

  • Focused Inbox (previously known as Clutter)
  • Threaded conversations (influenced by chat and social platforms)
  • Integration with new applications like DocuSign for digital signing and LinkedIn for in-context business intelligence

Second and most impactful would be the introduction of Email as a Service via products like Exchange Online, part of Microsoft Office 365. Removing the massive burden of maintaining and scaling out email for an organization has allowed them to focus on what’s much more important: the business.

Email in the Cloud: Microsoft Exchange Online

Email is quickly shifting to the cloud, primarily because of how easy it is to move Exchange server data to the cloud. Migrating Microsoft Exchange to Exchange Online is often the first step companies make when beginning their transition to Office 365. It is one of the few technological transitions today that happens seamlessly. Most users experience no negative impact while an Exchange migration happens on the backend.

Managing Exchange in the cloud becomes a much simpler process for administrators, as the need to maintain servers, network, and storage infrastructure vanishes. However, something that is often overlooked is how you are going to maintain a backup policy for your Exchange Online data and Office 365 Groups mailboxes. While Microsoft offers a 99.9% SLA for its services, this guarantee is only around  the service uptime – not data availability. For example, if there is a malicious attack on a Microsoft server which leads to data loss and corruption, they are on the hook for ensuring you get it back. However, if the fault is not on the provider (Microsoft in this case) then you’re out of luck. Some common scenarios we’ve seen with customers include:

  • Accidental Deletion: Even with a Recycle Bin, accidental deletion by end user is prevalent. Typically, it’s not through negligence or malicious intent, but rather an honest mistake. Critical emails may have been routed to the spam folder and purged. Spring cleaning and reorganizing folders might lead to data loss as well.
  • OneDrive for Business and Outlook Client Sync Issues: There is always a chance that during synchronization of content from your work laptop, phone, or tablet that the content can become disrupted during a network disruption.
  • Ransomware: A scary name matching an equally frightening reality. Ransomware is the forced encryption of data by malicious software. Without the keys, you can’t get to your data, and unlike legitimate encryption, only the bad guys have them. One of our customers went through this scenario themselves but luckily were a DocAve Backup and Restore To learn more about how they recovered from a Ransomware attack, check out our case study video here.

So we know email is important, and we know email needs to be protected. Now, let’s take a look at a few ways to do that:

Native Exchange Online Backup Capabilities

Users can restore email items that have been deleted from any email folder. When a user deletes an item, it is kept in the Deleted Items folder in the user mailbox until the user manually deletes them or moves them to another mailbox. They can also be removed via custom retention policies.











Manual deletion of Deleted Items folder

In addition, users have the option to set up an archiving policy to save their emails, but each end user must set up their own archiving system individually.













Setting up custom retention policies for Deleted Items folder

If a user permanently deletes an item in Outlook, the item is moved to a folder (Recoverable Items > Deletions) and kept there for 14 days by default, but this can be changed to any amount up to 30 days. Admins can do an item restore from this folder at the request of the user. However, once an email or user mailbox has been deleted for more than 30 days, it unrecoverable.

This limits the capability of a company to maintain organizational retention policies for their data stored in email, and provides limited functionality for actual data recovery if someone deletes content from their “Deleted Items” folder.

Whether backing up your data is simply a comforting safeguard or an service level agreement- (SLA) driven, auditable process, it is clear native functionalities restrict what you are able to do with Exchange Online backup.
