Hi,

Yes the whole process was running according to technet documentation.

This is where I ran in to the problem.

Hello,

I suggest you run get-publicfolderdatabase on exchange 2010 to check the public folder datbase.

Please describe your environment detailed.

If there is any error in application log, please post the event source and event id.

If you have any feedback on our support, please click here

get-publicfolderdatabase returns my public folder database.

just get cmdlet failed error in the event log when running the shell command.

and the error in shell is:

Couldn't connect to the source mailbox.
    + CategoryInfo          : NotSpecified: (:) [New-PublicFolderMigrationRequest], RemoteTransientException
    + FullyQualifiedErrorId : 960CE187,Microsoft.Exchange.Management.RecipientTasks.NewPublicFolderMigrationRequest
    + PSComputerName        : exch2013.domain.com

Does anyone prehaps have Public Folder migration guide other than the technet supplied by microsoft?

Maybe I am missing something?

Ok. Still stuck but one question.

During the process I create 2 CSV Files.

1. Publicfolderstatistics

2. PublicFolderToMailboxMapGenerator

When running the New-PublicFolderMigrationRequest  wich CSV am i meant to refrence? I am refrencing the PublicFolderToMailboxMapGenerator.

This is the content of the csv file:

"FolderPath","TargetMailbox"
"\","mailbox1"

I created a public folder named mailbox1 on the exch 2013 server using the -holdformigr

Hello,

Per my known, I consider you are right.

Besides, you create the name of the public folder mailboxes that must match the name of the TargetMailbox in the mapping file.

Hi,

I had the same problem of migrating my public folder from Exchange 2007 SP3 to exchange 2013. After reading the technet's guide more carefully, I tried to install Update Rollup 10 for Exchange 2007 server and then New-PublicFolderMigrationRequest command worked fine. 

Hence, I think there are some updates required for Exchange 2010 SP3 as well.

I had the same problem (Couldn't connect to the source mailbox), when began Public folders migration from Exchange 2007 SP3 RU10 to Exchange 2013 CU1.

I tried Test-MAPIConnectivity -server **** | fl  , and get error:

No mailboxes were found on the server "****" to perform the operation.

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.

Bingo!

That did the trick.

Thanks.

Gil...which part did the trick the creation of empty mailbox database or the SP3 RU10 update?

Hi, I was using Exchange 2010 not 2007 so no RU10....

the problm was not the mailbox, it was the databsae.

I had deleted the users database after migrating all users and this affected Public folder mgration. creating an empty database fixed the issue.
