Email Migration

A law firm engaged us to migrate their email system from a legacy platform with limited functionality to Microsoft 365. The goal was to improve security, increase mailbox capabilities, and provide access to the full Microsoft 365 ecosystem at a more cost-effective price point.

Case Breakdown

A detailed look at the challenge, our approach, and the measurable outcome.

The Challenge

The firm was operating on an outdated legacy email system with strict mailbox size limits, no multi-factor authentication (MFA), and high costs relative to the limited features provided. The environment consisted of 100 inboxes supporting 75 users, making downtime and data integrity a major concern. Any disruption during business hours would directly impact legal operations, so a seamless migration was critical.

The Solution

We planned and executed a full email migration to Microsoft 365 with minimal business disruption. Key steps included:

Full data backup of all 100 inboxes prior to migration to ensure zero data loss
Coordination with firm management to identify the optimal cutover window
A planned overnight migration to avoid operational impact during business hours
Weekend on-call support immediately following the cutover
Live support on Monday for all 75 users returning to work
Clear step-by-step documentation for reconfiguring email on desktops and mobile devices

We also implemented a structured user validation process. On go-live, we proactively contacted users to confirm functionality. For employees on PTO or unavailable, we tracked follow-ups and did not consider the project complete until every user was reached and successfully reconnected.

The Result

By Thursday of the same week, 100% of inboxes and all 75 users were fully migrated and operational across all devices. The firm gained access to the full Microsoft 365 platform, enhanced email security, and significantly expanded mailbox capabilities at a better overall value. Users who required additional help received one-on-one onboarding and guidance, resulting in a smooth transition with minimal disruption.
