Legal Customer Service Success Story Booklet

The Customer

A large law firm practicing in over 20 legal service areas with 150 employees and four office locations throughout the Gulf Coast wanted to modernize their email communications by migrating from an on-premises Microsoft Exchange email server to Microsoft 365. With email serving as the backbone of the firm’s operations and communications, and zero tolerance for downtime or interruption, the firm needed a migration strategy that was proven, well-understood, and strategic. It would take a highly experienced Microsoft Solutions Partner to deliver on these needs.

The Customer’s Challenges:

for downtime or interruption

150+ User Mailboxes
