The public folder database ‘Public Folder Database 0206806109″ cannot be deleted
If you are migrating from an earlier version of Exchange to a newer version , you may come across a situation where you are not able to decommission the old exchange server due to the inability to delete the Public Folder databases with the below error message.
Public Folder Database 0206806109
Failed
Error:
The public folder database “Public Folder Database 0206806109” 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 database, see http://go.microsoft.com/fwlink/?linkid=81409&clcid=0x409.
You may opt to use the ADSI edit to forcibly delete the Public folder. But , I would not recommend this approach as the ADSI Tool there is no error check or validation is performed.
You can use the below powershell commands to safely delete the replicas of the remaining Public folders and System public folders after ensuring all the needed Public Folders are migrated to the new exchange servers.
Get-PublicFolder-ServerExch-2010 "\NON_IPM_SUBTREE"-Recurse-ResultSize:Unlimited | Remove-PublicFolder-ServerExch-2010-Recurse-ErrorAction:SilentlyContinue
Now you could remove the Publice folder dataabsae

How to check the AD Schema version
We all know , how to check the FFL & DFL version using the AD Snap-ins.However , if you want to check the AD schema version , you need to run regsvr32 schmmgmt.dll to active the MMC snap-in to get the required details.
Most of the time this process will fail and need additional troubleshooting steps. Instead of that , you can use the below PowerShell command to easily get the AD schema version. In the meantime , you could still use the ADSI Edit as well.
Get-ADObject (Get-ADRootDSE).schemaNamingContext -Property objectVersion
Output of the above command will give you a value for the ObjectVersion. This value need to be compared with below to obtain the correct schema version.

How to import Users to Windows 2012 Active Directory using PowerShell
Hi Guys
In many AD installations I do come across requirements to create multiple users in Active Directory(More than 200 in many cases) .In these cases we could use the below mentioned CSV template and use the PS command to directly import the users in to Active Directory.
Here the Path value is pointing to the OU that you want to place the users in the Active Directory , which could be find using the Attribute Editor of the OU(We need to enable the Advance Feature in the ADUC Management Console)
PS Command Syntax
Import-CSV C:\anyname.csv | New-ADUser –AccountPassword (ConvertTo-SecureString –AsPlaintext “any complex password” –Force) –PassThru | Enable-ADAccount.
Example:
Import-CSV C:\Users_1.csv | New-ADUser –AccountPassword (ConvertTo-SecureString –AsPlaintext “P@ssw0rd” –Force) –PassThru | Enable-ADAccount
Update2:
I am including here another method to achieve the same.
# Prepare the CSV file as per below(You could any details as much as you want, by adding the correct attribute.)
firstname,lastname,username,email,department,password,jobtitle,company,ou,Mobile
# Then run the below powershell.
+ You must change the active directory domain name.
+ You must change the csv file name.
+ Ensure that , you have given the proper DN namespace for the OU Value. Otherwise , the script will fail with the below error messages:
“No superior reference has been configured for the directory”
“New-ADUser : The object name has bad syntax”
