What We Migrate
All types of Public Folders (appointment, contact, journal, mail, note, task, and so on) can be migrated in case they are supported in the target tenant.
Please consider the following migration specifics:
- If the public folder with the same path already exists on the target, the source public folder will not be migrated. Check the Events tab.
- The first processed mailbox will be set as a primary for a public folder. Other mailboxes will be set as secondary public folder mailboxes.
- Send As and Send on Behalf properties will only be transferred for mail-enabled Public Folders.
- Read and unread status is not migrated.

- Click the task name on the widget to see the details or use Show all link.
Once the discovery task is complete, you will see the source domain’s public folder summary on the Public Folders Migration Project Dashboard.
