Question

Hi. Exchange 2016, on-premise, last cu, last su.

I've lost the shared folder base. It is not possible to restore it. How to forcibly delete them?

If you delete the database from ADSIEDIT, the boxes are still in the /ECP. Because of this, the clients to which the boxes were connected cannot log in to Outlook.

There is a known issue on Exchange 2016 regarding the deletion of public folders. After you delete a public folder from the EAC, but when you run Get-MailboxStatistics, you will notice that the public folder mailbox is still displayed. In this case, you should use EMS to permanently delete the public folder mailbox using the command "Remove- MailboxStatistics".

Remove-StoreMailbox -Database “DBname” -Identity “GUID of the disabled PF mailbox” -MailboxState Disabled

In addition, you can also use ADSIEDIT to clean up AD:

Open ADSIEDIT>Connect to the Configuration partition>Drill down to "Services > Microsoft Exchange > YourExchangeOrg > Administrative Groups > YourAdminGroup > Databases">Right-click and delete the database object
