1. Key Challenges in Exchange 2013 Public Folder Migration with Solutions

   1. Public folder size and item count limitations:

      Solution: EdbMails simplifies large-scale public folder migrations, Microsoft 365 imposes size limits per public folder mailbox. To avoid failures:

      • Split large public folders into smaller mailboxes before migration.
      • Review and increase Office 365 public folder quotas if necessary.
      • Use incremental migration in EdbMails to transfer only new or changed items, reducing the data load in each cycle.
   2. Handling large hierarchies and subfolders:

      Challenge: Public folders often contain complex hierarchies and thousands of subfolders, making it difficult to ensure accurate mapping and migration continuity.

      Solution: EdbMails preserves the complete folder structure and hierarchy during public folder migration, ensuring that all subfolders and items are migrated exactly as they exist in the source Exchange server.

   3. Throttling and connection issues during bulk migration:
