Hi @Chong ,
Thanks for posting in our Q&A forum.
First of all, please check the removed DB status, use the cmdlets Get-MailboxDatabaseCopyStatus
.
If you want to stop Exchange database’s index folder from recreating even after the database has been removed from the organization, you can disable indexing for that mailbox database. To do so, use the following PowerShell command:
Set-MailboxDatabase <DatabaseName> -IndexEnabled $False
You can verify that indexing is disabled by running the following command:
Get-MailboxDatabase <DatabaseName> | fl Name,IndexEnabled
If there are any update, feel free to let us know.
