Hi All,

When performing the new-publicfoldermigrationrequest command on exchange 2013 server I receive the following error:

Couldn't connect to the source mailbox.
    + CategoryInfo          : NotSpecified: (:) [New-PublicFolderMigrationRequest], RemoteTransientException
    + FullyQualifiedErrorId : 19495301,Microsoft.Exchange.Management.RecipientTasks.NewPublicFolderMigrationRequest
    + PSComputerName        : svr12365.bcb.local

I am copying from Exchange 2007 on sbs2008 server. if I run get-publicfolderdatabase from exchange 2013 powershell it returns with the correct database name and server.

any ideas?

Many Thanks

Hi
Can you get public folder mailbox? Maybe it is mailbox issue.

Nore: The name of the public folder mailboxes that you create must match the name of the TargetMailbox in the mapping file. You can edit the TargetMailbox names in the mapping file to match your organizations naming conventi

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.
