We have created a new comprehensive guide to migrating public folders to help those faced with such a project. The guide provides a detailed outline across 13 steps including undocumented quirks and challenges inherent with Microsoft Exchange Public Folders. The guide was born out of the past few years in which Priasoft Consulting Services led several very large projects from start to finish.

Recent activities with some very large customers, one with over 20 terabytes of data and more than 470,000 folders in the hierarchy, has given our team unique insight and experience that is now being shared so that others may achieve the same success.

Public Folders are just not a simple problem. They are complex regardless of total size and there are many oddities and idiosyncrasies that are rarely or never exposed or explained – by Microsoft or others. This guide tries to expose as much details as possible while at the same time presenting it in a way that can be understood.
