3. Launch the Application: After installation, open the program from the Start menu (Windows) or Applications folder (macOS). The first launch may request administrator privileges to configure network settings.
4. Configure Source & Destination Accounts: In the main dashboard, click “Add Gmail Account” and provide OAuth credentials. Then add your Office 365 tenant details (admin account, tenant ID, and client secret). The tool validates both connections automatically.
5. Select Migration Options: Choose the mailboxes you wish to migrate, apply date‑range filters, decide whether to include attachments, and enable the “Skip Duplicates” toggle.
6. Start the Migration: Click “Start Migration”. A progress bar displays real‑time status, and logs are written to the logs directory for later review.
7. Review Results: Once completed, the summary screen shows migrated items, any errors, and suggestions for post‑migration cleanup.

Compatibility: The software is built on .NET Core, making it fully compatible with Windows 10/11 (64‑bit) and macOS 10.15 Catalina or later. While there is no native Linux version, the tool can run under Wine or a Windows virtual machine if needed.

For organizations with mixed environments, you can install the application on a dedicated migration server and grant remote access to IT staff via RDP or VNC. The tool also supports command‑line arguments, enabling integration with PowerShell scripts or CI/CD pipelines for fully automated migrations.

Security‑conscious users will appreciate that all credentials are stored only in memory and never written to disk. The application adheres to the principle of least privilege, requesting only the scopes necessary for reading Gmail messages and writing to Office 365 mailboxes.
