Analyse your current public folder hierarchy

Visualise and drill into your public folders before migration to size up the effort and make informed decisions on what needs moving and where…and whether it needs moving at all.

Ensure a seamless end-user experience

By checking for mail-enabled folders, data ownership, and permissions in advance you can ensure that public folders behave correctly for on-premises and cloud-based users as they migrate.

Zero-downtime migration methodology

We can ensure your migration allows business activities to continue uninterrupted, with the option to synchronise content between on-prem and the cloud.

Cope with complexity

Modern public folders have many sizing requirements.  For example, your legacy public folder hierarchies may be too big to map directly into Microsoft 365.  We can help you tackle these niggling issues in advance of your move.

Escape the shackles of legacy workloads. Harness the benefits of Microsoft 365 any place, anywhere collaboration & Azure flexibility.


Migrate public folders to a range of locations

Essential delivers migration without downtime to a range of different targets:

  • Modern public folders online: Easily migrate public folders from Microsoft Exchange Server 2010, 2013, and 2016 to modern public folder mailboxes in Microsoft 365
  • Microsoft 365 groups: We provide you with the easiest process for mapping your Public Folder contents into the Microsoft 365 groups model. By migrating Exchange on-premises public folders to groups you can enhance social collaboration features across mail, calendar and content while reducing the costs associated with public folder management.
  • SharePoint online: Move public folder content that is often updated (such as company policies) into SharePoint online, and share it out using more appropriate methods.


The challenge was to migrate 11TB of Public Folders for our 5,000 users, which the Essential team carried out professionally with a minimum of downtime.
