Hi,

I am trying to run the below command but with the following error:

New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server HO-EX2010-PF) -CSVData (Get-Content C:\PFMigration\PFMailboxMap.csv -Encoding Byte)

However I am getting the following error:

Object Reference not set to an instance of the object

I can see this in event viewer but it doesn't seem to give much detail, anyone else seen this?

(PID 2280, Thread 11) Task New-PublicFolderMigrationRequest throwing unhandled exception: System.NullReferenceException: Object reference not set to an instance of an object.

Many Thanks

What happens if you just put the database identity in there instead of the Get-PublicFolderDatabase?

Or, try one of the following cmdlets.

New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server HO-EX2010-PF).Identity -CSVData (Get-Content C:\PFMigration\PFMailboxMap.csv -Encoding Byte)

or

New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server HO-EX2010-PF).DistinguishedName -CSVData (Get-Content C:\PFMigration\PFMailboxMap.csv -Encoding Byte)

Hi,

At times in Exchange 2013, If you remove the Public Folder Mailbox which holds the Master hierarchy abruptly, or deleting Using Adsiedit.msc , It doesnt get removed properly. Where as a result of that master hierarchy goes disappeared. Even if you Create Public Folders it will create as Secondary hierarchy.

So in the First place. We need to check the Hidden Master hierarchy. Running the Below Command, it will show Which mailbox is the Master hierarchy.

Get-OrganizationConfig | Format-List Name,RootPublicFolderMailbox

Get the ExchangeGuid Value from RootPubicFolderMailbox, and then run

Get-Mailbox PublicFolder | FL Name,ExchangeGuid

Now you should see which Public Folder holds the Master hierarchy. Post and let me know the result.

Best Regards.
