Hi Guys

Need some help, im trying to remove the last exchange server on my org, but i got this error.

Uninstall cannot continue. Database 'PublicDB01': The public folder database "PublicDB01" contains folder replicas. Before deleting the public folder database, remove the folders or move the replicas to another public folder database. For detailed instructions about how to remove a public folder.

I already try using the console to remove any replicas, and i only got the Internet Newsgroups. And the only replica is the local public database itself.

Try also the removereplicafrompfrecursive.ps1 and the moveallreplicas.ps1 without success. I want to remove it using the cleanest method, and not forcing it from the ADSI edit.

Any help is appreciated. Thank you

    Since Exchange caches information, as does IIS sometimes we need to simply allow time. The same is also true for Active Directory. Depending on the environment, AD replication latency may also need to be factored in. This may take hours. For a large enterprise, do not expect to run through all of the decommission tasks in a 30 minute maintenance window.

    Hi @BrunoRocha-4314

    Have you run the following commands to delete user public folders and system public folders:

    Get-PublicFolder -Server <server containing the public folder database> "\" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server <server containing the public folder database> -Recurse -ErrorAction:SilentlyContinue  
      
    Get-PublicFolder -Server <server containing the public folder database> "\Non_Ipm_Subtree" -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server <server containing the public folder database> -Recurse -ErrorAction:SilentlyContinue  
    

    If not yet, please run the commands first and check if you can successfully remove the public folder database to uninstall Exchange.

    Here are also two links for your reference:
