Public Folders can contain years of shared business information, including emails, discussions, and important records. When an organization plans to restructure its Exchange environment or move to another Microsoft 365 tenant, administrators need to decide how this information should be retained and accessed afterward. Simply moving user mailboxes may not cover every requirement, especially when teams still depend on shared Public Folder data.

One common requirement is to export Public Folder to PST so that the data can be stored locally or retained for future reference. Before starting, administrators should identify which Public Folders are important, review their contents, and decide whether the data needs to be archived or restored into another mailbox environment. It is also worth checking the available folder structure and the destination requirements.

The SysInfo Office 365 Backup Tool supports Public Folder mailboxes as part of its Microsoft 365 tenant-to-tenant migration capabilities. It can also migrate supported mailbox data, including emails, contacts, calendars, tasks, notes, rules, and permissions. Administrators can map source and destination mailboxes, apply filters, and use the Skip Previously Migrated Data option when running an incremental migration.

For organizations that need to backup Office 365 mailbox data, it is important to define the scope first. Decide which mailboxes and items need protection, whether shared or archive mailboxes are involved, and how historical data will be accessed. The tool also supports restoring PST and OST files into Office 365, with a PST corruption check available before restoration.

When comparing Office 365 backup software, I would suggest checking mailbox coverage, authentication methods, filtering options, duplicate removal, and reporting rather than looking only at the number of supported file formats. A small test with selected data can help administrators understand the workflow before handling a larger project.

How does your organization handle Public Folder data during tenant changes? Do you prefer keeping a separate PST archive or migrating the required content into the new Microsoft 365 environment?
