I am migrating public folders, but it is giving me an error.

Error: failed to migrate public folder, it may be deleted intentionally

Cannot create public folder hierarchy to complete the task.

We have Public folder in Forest A, Forest B and  Forest C Exchange 2016 on-prem which need to be migrated to Office 365 exchange online.  Which tool we can use to migrate to office 365 and is it possible to migrate all the forest public folder to EXO one…
