Public Folders (On-promise to Cloud)

I have migrated Public folders from on-promise to cloud using PST file.

It's all there but now I have to disable the mail enabled PF in the on promise and put the same in PF in cloud.

but when I try it gives the error:
 The proxy address "smtp:" is already being used by the proxy addresses or LegacyExchangeDN of "". Please choose another proxy address.

I cannot see the SMTP in the on-promise anymore, so it should not exist....
so the problem is that I cannot enable PF mail enable on the cloud and need to do this before set the organization to use just cloud PF.

Thanks in advance,
