EXCHANGE 2016: FIND REMAINING FOLDERS OF DELETE OR NON EXISTING DATABASES

Story

Let’s assume that you work for a company that has Exchange 2016 and has big amount of databases (50-100 DB).

You constantly delete databases to clear white space or for whatever reason but don’t usually keep on deleting folders or lost track of which database is deleted in your DB Folder.

Real Life Scenario

In the following PowerShell script I am going to demonstrate how to check which of the folders in my D drive (Database drive) has an existing Database and which do not have.

Databases Folder path

OutPut:

Script

The below script gets all folders in the drive path D:\Databases to check if they exist or not.

# Get deleted database that still has remaining non deleted folders
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn
$databases = Get-ChildItem D:\Databases\*  -Directory | select Name

foreach ($database in $databases)
{
        $DB = $database.Name
        if ((Get-MailboxDatabase -Identity $db -ErrorAction Ignore ))
            {
            write-host "Database $($db) exists on Exchange Server" -ForegroundColor Green
            }
                else
                {
                Write-Host "Database $($db) doesn't exist on Exchange Server " -ForegroundColor Red
                }
}

I did not add the part to delete the folder through the script as it is still a risky thing to automate and would rather do the deletion manually after double confirming it’s totally gone.

Changing RDWeb default Port on Windows Server 2019

Story:

When you install RDS on a server which uses the port 443, you will get the following error when you try to access RDWeb main page.

Reason for this is the server you installed RDWeb on is most likely already using the port 443 or something else.

Error Message:

When trying to access RDWeb on the same server you’ll get the following error:

Service Unavailable

Http Error 503. The Service is unavailable
