St. Louis Law Firm – New Office Location

February 18, 2025

New Office Location Our client, a St. Louis Law Firm, had outgrown their office’s capacity and requested The Miller Group to assist them with moving to their new office location. We took this time to review their existing network equipment and made recommendations to replace their network equipment during the office move. This suggestion was to utilize the timing of their office move, while increasing the security and performance of their network. The Problem This St. Louis Law Firm is looking to migrate their users and associated domain from their current email solution to an Office 365 tenant. This transition requires moving all email data and ensuring security measures are in place, while also complying with industry standards, such as a 7-year email retention policy. The Solution The Miller Group (TMG) started with migrating the users to Office 365 by manually transferring PST files remotely into the new mailboxes. Additionally, TMG assisted users with setting up Multifactor Authentication (MFA) to secure their new Office 365 accounts. This will ensure the security of all emails and cloud data. The Result By migrating to Office 365, the Law Firm will meet its compliance requirements, including the necessary 7-year email retention. The migration also grants them access to Microsoft’s industry-leading email hosting service and the full Microsoft 365 Office product suite. However, the migration will not involve using a separate licensed tool for the email transfer.”
