We are receiving the following error when attempting to migrate Public Folders
"Failed to create public folder, reason: The specified parent folder could not be found. Cannot create public folder hierarchy to complete the task. Current running task"
To migrate public folders to or from Microsoft 365, the administrator account used by On Demand Migration (ODM) must have root-level permissions on the public folders.
Follow the steps below:
Sign in to the Microsoft 365 admin account.
In the top-left corner, select the App Launcher (grid icon).
Select Admin to open the Microsoft 365 admin center.
In the left-hand navigation pane, scroll down to Admin centers and expand the section if needed.
Select Exchange to open the Exchange admin center.
Select Public folders from the Exchange admin center.
Locate the public folder list. Select the More options (three dots) menu and then select Root permissions.
In the Root permissions window, select the + icon, select Browse, and choose the administrator account that will be used for the migration.
From the permissions drop-down menu, select Owner.
Ensure that all available permission options are selected.
Select Save to apply the changes. Spot-check the top-level public folder and its subfolders to confirm that the ODM service account has the required permissions.
Allow up to 60 minutes for the permission changes to replicate.
In the ODM Public Folders dashboard, open Configure Connections and verify the source and target connections. It is recommended to type the password into Notepad first and then copy and paste it into ODM to help avoid password entry errors.
In ODM Public Folders, delete the existing public folders.
Run the Discover Public Folders task.
After discovery completes, run the Migrate Public Folders task.
