What makes Allegient Services' email migration approach unique?

Allegient Services has a tried-and-tested approach to complex Exchange migrations to Microsoft 365, taking care of everything from legacy Lotus Notes environments to hybrid setups. Their own tools take care of public folder migrations, calendar coexistence, and mail flow routing with minimal disruption. For a 20,000-user company, they performed a phased migration in three months that involved message journaling for compliance and SMTP routing changes for 150 subsidiaries. After migration, they tune Outlook performance using Cached Exchange Mode and OST file management policies in the Microsoft 365 environment.
