Exchange public folder migration

Public folders in Microsoft Exchange are used to store and share emails, calendars, contacts, and documents across teams. Migrating these folders to a new Exchange server or a newer version can be challenging. Native methods often involve complex scripts, manual steps, and careful planning, which can make the process time-consuming and prone to errors—especially in large organizations or environments with many folders and subfolders.

If not handled properly, migration issues can result in broken folder structures, lost permissions, or downtime for users. Since public folders are a central part of team collaboration, such problems can disrupt productivity, increase administrative work, and affect business operations.
