Exchange Public folder to Office 365 migration simplified using EdbMails

Exchange Public folders were introduced as a method of creating a collaborative space for sharing information within a workgroup or organization. They were used to share calendars, documents, and contacts in the absence of a mail-enabled feature. In later versions of Exchange, public folders were mail-enabled, allowing users to send and receive emails from them. Public folders work similarly to a container in which you can store files and other information that other users with access to those files can view. It is a quick and simple way to collect, organize, and share information with the employees of the organization. Unlike a Shared Mailbox, a public folder does not have an associated email address. Previously, public folders had their own public folder database. When they were mail-enabled, public folders were integrated into the mailboxes using database availability group (DAG), and the previous architecture was done away with. A public folder’s permissions can be assigned and removed by an Exchange administrator, and they can be shared among multiple users in a specific group or team to collaborate on a project. It is important to understand that public folders have a deep hierarchy, which Exchange administrators can define and assign ownership status to different parts of the hierarchy to reduce administrative burden. The delegated owners can then manage permissions directly from Outlook. In this article, we’ll look at the challenges of migrating Exchange public folders to Office 365, as well as how EdbMails Exchange public folder migration tool can help.

What are the challenges of migrating Exchange public folders?

Many users prefer to migrate to Office 365 in order to take advantage of the cutting-edge collaborative features. When an organization has a large number of public folders, migrating them can be a never-ending task. Before we get into how to migrate public folders, it’s important to first understand the challenges.

  • Public folders, as previously stated, are organized in a deep hierarchy, and it is not uncommon for an organization to have a large number of public folders.
  • Second, unlike in the past, public folders are now part of mailboxes and do not require a separate database. Users who want to migrate from a legacy version of Exchange to Exchange 2016, 2019, or Office 365 must consider this factor additionally.
  • Users may be frustrated by public folder mailbox size limits, and the complex hierarchy may be intimidating if you only want to migrate data selectively from public folders.
  • Microsoft’s native method of migrating public folders necessitates the execution of PowerShell scripts, which may not ensure data consistency when migrating from older versions of Exchange to the most recent ones.
  • Traditional methods of migrating public folders, or doing it manually without any tools, take a long time.
  • Downtime is common, and important resources are tied-up when administrators migrate public folders on their own.
  • You cannot view or migrate public folders, if the Exchange database is severely corrupted.
