Helping Oasis Fashion to FastTrack and secure their adoption of Microsoft 365

The Business Drivers

Oasis began its journey to Office 365 around three years ago, initially moving on-premise email infrastructure to the cloud. Following a successful migration of their email platform, they wanted to expand modern workplace adoption to tap into the new solutions and initiatives that the broader Microsoft 365 portfolio could offer. Oasis was also keen to address the imminent and future security risks to protect their organisation, staff, customers and ultimately, the brand.

Richard Surman, Head of IT at Oasis explains: “It was obvious we weren’t leveraging the full Microsoft 365 solution and we wanted to limit the potential for security risks.”

Why Trustmarque was selected as a partner

As a highly respected Microsoft partner, and one of only 12 Microsoft UK FastTrack partners, Trustmarque was recommended to Oasis and Warehouse by Microsoft directly. Former sister brand Karen Millen also provided a “very strong endorsement”, says Richard, following a successful project onboarding Office 365 across the organisation.

Trustmarque had a thorough understanding of all products available under the Oasis and Warehouse online services suite and how to utilise them in order to deliver maximum benefit in conjunction with existing Microsoft online services. We were able to clearly demonstrate how we would layer this with our deep Microsoft expertise to provide both technical and consultative support in the complex world of licensing, security and user adoption.

The solution

The engagement began with an initial consultation and Microsoft 365 Security Risk Assessment followed by the delivery of Trustmarque’s FastTrack Ready Service. The service included a dedicated FastTrack Manager who was able to work with Oasis and Warehouse on their migration and adoption roadmap. They have successfully migrated approximately 3000 users across the company to Office 365 and are now drawing on Trustmarque as a consultative partner to provide expert advice on the most cost-effective way to consume the online services so they can manage the adoption in-house.

Richard commented: “It’s great to have the reassurance that we have a fleet of professionals behind us that we can call on to assist. Trustmarque clearly has the experience to support whenever we need it.”

Sustained collaboration through engagement with the Trustmarque FastTrack Manager also led to identification of Microsoft Intune as the most effective business solution for Oasis and Warehouse.

Outcomes and feedback

They have been satisfied with all areas of the project, says Richard:

“The security part of Microsoft 365 was very thorough, and Trustmarque managed to do everything remotely – meaning there was minimal disruption for the business. I simply gave the Trustmarque team access to the portal and they gave me recommendations, which have been implemented. I have been very impressed with what we delivered to date. Everyone is happy.”

He revealed a few early teething problems with Teams, largely due to Oasis and Warehouse being an early adopter. However, he commended both Trustmarque and Microsoft for their “collaborative and proactive” approach in investigating the issues and providing the right service to Oasis and its end users as quickly
as possible. As a result, the’ migration to Teams is complete and Richard says Teams will replace WhatsApp as the brand communication channel to ensure better governance.

Next Steps

Richard says his primary goal is to migrate “as much as possible to the platform, to leverage and utilise the capabilities of Microsoft 365”. As part of that adoption journey, the next key area of focus will be SharePoint, which he hopes to have rolled out by the end of the year.

In addition, Trustmarque will continue with the comprehensive Microsoft InTune engagement with Oasis and Warehouse. The aim, says Richard, is to “enhance the product offering to our end user”. Intune provides mobile device management and single sign on, ensuring all company-owned and bring-your-own (BYO) devices are managed properly and kept up to date.

Trustmarque’s Workplace FastTrack Manager, Jordan Berger, commented: “FastTrack can pave the way for us to work with customers like Oasis on their wide digital transformation strategy. Using FastTrack as a basis, we can identify specific areas of improvement, perhaps where a customer may not be totally comfortable and we can provide additional support. The benefit to the customer is that it becomes a targeted and consolidated effort, providing cost efficiencies.”
