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.

When deploying Skype for business, you might want to deploy a Hybrid deployment where users are hosted on both on-premises servers and on Office 365 Skype for business.

In this case You’ll need to make sure that integration is working and that you can move users directly from the SfB Control panel without even needing the use of Powershell.

Although sometimes it’s easy but problems could rise anytime like the one below.

Error

HostedMigration fault: Error=(507), Description=(The user could not be moved because he or she has not been an assigned a Skype for Business Online license. Users must be licensed before they can be moved to Skype for Business Online.)

Cause:

In case you wanted to move a user from on-prem s4b to Online and you get this error … then most likely you didn’t assign the user a license after you have used DirSync or Azure AD connect to sync this user.

Resolution:

Login to your O365 Portal and assign the user a license or subscription that includes Office 365 Skype for Business Online … then try to move the user

I assigned a license

For changes to take effect, I will go to Dirsync and force the user to be synced..

If the moved user that was moved is logged on, it will log off and try to login with Skype for business Online

Moving users from cloud to on-prem.

Moving user at 4:05PM Exactly. The client disconnected automatically and kept on trying to connect again.

It took the client about 2.5 minutes to connect back to the user after he was successfully moved back to on-premises

EXPORTING AND IMPORTING GROUP POLICY OBJECTS – WINDOWS SERVER 2008

 

There may be times when it is useful to use an existing Group Policy Object (GPO) as a template for a GPO on another server, or perhaps you just need to perform a GPO backup and restore. Here is how to export and import GPOs from the command line.

Starting the Group Policy Cmdlet in Powershell

Firstly, from the command line start powershell and import the Group Policy Cmdlet:

Exporting a GPO

Check that the backup directory you wish to use exists. If not, create it.

Powershell command:

Example: to backup a GPO called “Example GPO” to the directory “C:GPOBackup”

Importing a GPO

Keeping the same GPO Name

Powershell command:

Example: to import a GPO called “Example GPO” from the directory “C:GPOBackup”

Renaming the GPO

Powershell command:

Example: to import a GPO called “Example GPO”, renaming it to “New GPO”, from the directory “C:GPOBackup”
