About Hilton

Hilton is a leading global hospitality company with a portfolio of 18 world-class brands comprising more than 6,700 properties and more than 1 million rooms, in 122 countries and territories. Hilton has welcomed more than 3 billion guests in its more than 100-year history, earned a top spot on the 2021 World’s Best Workplaces list, and been recognized as a global leader on the Dow Jones Sustainability Indices for five consecutive years.

Thanks to harmon.ie, Hilton can provide users with a single source of truth with no version control issues. Hilton’s userbase has been empowered to help build the business information repository that they all use each day, fostering a stronger sense of community beyond individual sites.


Having just celebrated their centenary, Hilton continues to dominate its industry. The key to their success? They invest in innovative solutions for not only better customer experiences, but better employee experiences.

In the ordinary course of business, Hilton built up a backlog of old records; emails and documents: this included millions of old emails, many of which employees were hesitant to delete. With so much information across their systems, Hilton faced compliance risks caused by outdated information, as well as employees were running into collaboration issues, such as file versioning, and valuable information being lost.

Hilton partnered with harmon.ie to eliminate the risk caused by keeping old emails, and to preserve important documents of record. With harmon.ie, Hilton was able to easily identify, categorize and catalog valuable records. Case in point, in a short, two-month period, Hilton was able to capture and catalog 40,000 valuable records, while dispose of over 35 million emails they didn’t need. The ability to capture and classify what was important while deleting what was not necessary is essential for corporate information governance.

“Using the capabilities of the harmon.ie tool we were able to successfully preserve important records while also deleting over 35 million emails out of our Exchange servers, which led to a significant decrease in risk… We were able to achieve all this through the capabilities of the harmon.ie tool and Office 365 and deploy that to 100% of our population of users… We wanted everything in that one interface and harmon.ie was able to do that for us.”

The Challenge

Drowning in emails

Email is still one of the primary methods of sharing business information, as well as internal and external communications between stakeholders of all kinds – however it isn’t always used effectively. Hilton used Outlook as their email client, and without an email retention policy, emails piled up. There wasn’t an easy way of categorizing them, so locating valuable information became a real struggle.

It was also difficult to mitigate legal risk, because millions of non-essential emails from previous years were still stored on their Exchange servers – for a company of Hilton’s size and stature, reducing information liabilities for the future was, and still is, a priority. Those old emails not only left Hilton vulnerable to legal action, they took up valuable server space.

Choosing the best tools

To create a secure environment for documents of record, including email, Hilton partnered with harmon.ie. Overall, their goal was to identify and preserve valuable information among the backlog of emails and deleting unnecessary emails from their servers.

To achieve this, a clear email retention policy had to be established. Hilton’s information governance department set a two-year retention limit; an appropriate amount of time to delete any non-vital emails. Not only did this eradicate the risk of storing old emails, it gave Hilton a fresh start for their document management.

Why harmon.ie

Tackling change management

A white labeled version of harmon.ie was created for Hilton, branded internally as “Declare”. Creating a Hilton-branded offering gave the hospitality giant the opportunity to ‘own the solution,’ so that every worker would take ownership of and contribute to, increasing the chances of success.

harmon.ie’s drag-and-drop functionality enabled workers to manage their own emails, which reduced the amount of manual inbox maintenance required by IT workers. Easy-to-apply metadata transformed the way workers were able to capture and classify emails, enabling them to then surface important business emails using common sense ‘tags.’ Bulk application of metadata also simplified storing documents of record, preventing easily avoided errors caused by repetitive tasks. These easy-to-use functions gave workers ownership of their inboxes and empowered them to uphold Hilton’s information retention policies without extra work.

Total email transformation

During the initial rollout period, Hilton employees have been able to locate and preserve 40,000 valuable records while deleting over 35 million redundant emails. A single source of truth has eliminated document chaos, ensuring that information is up-to-date and accessible. Across Hilton’s many departments, 15,000 users have been given access to Office 365 and harmon.ie – this represents 100% of Hilton’s email users.

Within Declare, bulk metadata editing made it possible to drag up to 100 emails at one time, drastically reducing the time it took to move emails. This was crucial for success: not only did it save employees valuable time, it also meant the overall project was completed quickly. With their new retention policy, information governance has been streamlined. This created a significant decrease in risk, and greatly reduced the amount of data stored.

The right tools for the job

harmon.ie helps any user manage their emails intelligently, storing them directly into SharePoint and applying metadata for easy retrieval. This simple functionality helps organizations combat information overload, keeping only necessary documents and discarding those without value. As Hilton expands, harmon.ie will remain a valued tool in their arsenal, as they transform their document management.
