The Legal Services Challenge

A 600-seat law firm was operating on a fragmented mix of on-premise Exchange, shared file servers, and consumer Dropbox accounts, exposing them to data compliance risk under UAE data protection law. They needed a unified, secure Microsoft 365 environment without disrupting active client matters.

Our Software Licenses Solution

As an authorised Microsoft partner, we designed the licensing structure, migrated all email, calendar, and document storage to Microsoft 365 and SharePoint, configured Intune for device management, and set up Microsoft Purview for data loss prevention and compliance archiving. Migration ran over three weekends with no business-hours disruption.

The Outcome

Full compliance with UAE Federal Decree-Law No. 45 of 2021 data protection requirements achieved at go-live. IT helpdesk tickets related to file access and email dropped by 44%. The firm achieved a 23% software cost reduction by consolidating vendors.

FAQ

Questions About Software Licenses

How do you migrate email and documents without disrupting active client matters?

We run all migrations in scheduled weekend windows using staged mailbox and file migration rather than a big-bang cut-over. Users continue working on the old system during the week; migrated data is validated and reconciled before the switch. For this law firm, three weekend migration windows covered all 600 seats with no business-hours disruption to active client matters.

What Microsoft 365 compliance tools are relevant for UAE law firms?

Microsoft Purview provides data loss prevention policies, litigation hold, and compliance archiving essential under UAE Federal Decree-Law No. 45 of 2021 data protection requirements. Microsoft Intune enables device management and conditional access to ensure only managed devices can access firm data. Both were deployed as part of this engagement.

How quickly can a Microsoft 365 migration be completed?

For a 600-seat organisation, allow 6–10 weeks total: 2 weeks for planning and pre-migration preparation, 3–4 weekends for staged migration windows, and a final week for validation and cutover. Smaller organisations can move significantly faster. We provide a detailed project plan with fixed milestone dates before any work begins.
