I was surprised to learn how many professionals still rely on Pegasus Mail. While it’s stable, it doesn’t fit well with cloud-based workflows. When I needed to migrate Pegasus Mail to Office 365, I didn’t want to risk data loss through manual exports. The SysInfo IMAP Backup Software made the process straightforward by automating authentication and mailbox selection. It even removed duplicate emails before migration, which helped clean years of clutter. This made the transition not just safer, but cleaner overall. Apart from this, the software allows you to convert emails selectively using the Data Filter option. You can choose a specific date range, and the tool will migrate only the emails from those selected dates.
