Did anything ever come of this tread? I have the exact same issue and have been told that MS is pushing people to groups. They don't work and you can't have subfolders..

Now we need to come up with a strategy regarding the data currently in Public Folders

We have looked at groups, but since its only possible to have "one folder, no subfolders" in a Office 365 Group, this can not replace Public Folders with this.

Then the question is, is Public Folders hosted in Office 365 any good?

And what is the future for Public Folders in Office 365, since Microsoft for many years have been talking about "the death of public folders".

Any input on this would be great :)

We decided to leave them on-prem for now. We will analyze our Public Folders and see what can be moved to Groups/Sharepoint etc.

Hi Michael

We have released the Public Folders to Groups tool. The documentation can be found here https://blogs.technet.microsoft.com/exchange/2017/09/25/migrate-your-public-folders-to-office-365-groups/

If you feel that Office 365 Groups do not work for you, you could still continue to use Public Folders. We do not have anything on our roadmap to deprecate Public Folders.
