  • Folder Organization: Allows users to create and manage folders.

  • No Calendar or Contacts Sync: IMAP is limited to email only.
  • Limited Offline Access: Full functionality requires an internet connection.
  • Minimal Security Features: Lacks enterprise-grade security controls.

Microsoft Exchange Server

Exchange is Microsoft’s enterprise-grade email server and collaboration system. Apart from handling emails, it syncs calendars, contacts, tasks, and more. Exchange is commonly used by organizations that require advanced collaboration tools and enhanced security.
