Hi

Ive run all scripts to get the csv files and after creating the public folder mailbox on exchange 2013 with the command:

New-Mailbox -PublicFolder MailboxName -HoldForMigration:$true

Then when running the command for starting the migration:

New-PublicFolderMigrationRequest -SourceDatabase (Get-PublicFolderDatabase -Server <Source server name>) -CSVData (Get-Content <Folder to mailbox map path> -Encoding Byte)

i get the following error:

Couldn't connect to the source mailbox.
    + CategoryInfo          : NotSpecified: (:) [New-PublicFolderMigrationRequest], RemoteTransientException
    + FullyQualifiedErrorId : [Server=ServerName,RequestId=76d6f674-c4d9-4c67-b0ff-bc16385551dd,TimeStamp=2015-02-24
    01:13:18] [FailureCategory=Cmdlet-RemoteTransientException] 69ADCDAD,Microsoft.Exchange.Management.RecipientTasks
  .NewPublicFolderMigrationRequest
    + PSComputerName        : fasad-mail01.fasadglas.sto

Ive search for the error code "RemoteTransientException" and all i get is that the mailbox should be corrupted and i have to remove it from the quarantine via regedit, but the quarantine is empty

thanks for your help

regards

Carlos

Please refer to this well explained blog post and it will help you a bit to understand the secret about public folder migration : http://thoughtsofanidlemind.com/2013/12/13/migration-modern-public-folders/

Also, I would like to refer you on this informative article that will provide you step-wise instructions to accomplish public folder migration in more easier way :http://www.petenetlive.com/KB/Article/0000789.htm

Moreover, if you still unable to achieve your goal, I would recommend you to have a look on this automated solution (http://www.exchangemailboxmigration.com/) that could be an appropriate alternative solution to get this job done in more easier way.

Dismount and Mount the Public Folder Database on Exchange 2010 and run the command again.

Hi

Thanks for your answers

@briskalcandy, ive read those blogs on how to migrate public folders. The problem is that the step where im going to begin the migration fails because of the error i posted

@Gulab, no luck when dismounting and mounting the database

What antivirus you are using? Check on the application too

no antivirus is installed on the servers

Hi Carlos,

According the error message, please make sure whether there is some mailbox database in this public folder.
I find a similar thread about your question, for your reference:
https://social.technet.microsoft.com/Forums/office/en-US/56080971-15e8-4227-8074-9ccc25c8cd74/couldnt-connect-to-the-source-mailbox-when-running-newpublicfoldermigrationrequest?forum=exchangesvrdeploy

The reason was, that old Exchange 2007 server had only one Public Folders database and no Mailbox databases. I create empty mailbox database on it, after AD replication across the forest command new-publicfoldermigrationrequest worked well.

Hi

I have a mailbox database on the same server as the public folder. The mailbox database only contains system mailbox but its there
