Public Folder Migration issues RRS feed

  • Question

  • Good morning, I am in the process of trying to migrate my exchange 2007 databases to Exchange 2013. I have been following a couple guides to do so. My environment has two exchange 2007 servers with public folders on them. When I try to run the new-publicfoldermigration request, I get : Couldn't switch the mailbox into sync source mode. I have tried restarting the replication service ,and dismounting and mounting the public folder database. Can anyone suggest what actions I should try next? I have deleted and readded the public folder mailbox on exchange 2013 a couple of times. thank you.

  • Have you reviewed this 4 part article? https://blogs.technet.microsoft.com/meamcs/2013/07/25/part-1-step-by-step-exchange-2007-to-2013-migration/


    Search, Recover, Export Mailboxes, Folders, Email, Contacts, Calendars, Tasks, etc. from Offline Exchange Databases (EDBs), On-Premise Exchange Servers and Office 365. Migrate/Recover direct from any offline EDB into any On-Premises Exchange Server, even cross version i.e. 2003 → 2007 → 2010 →2013 → 2016 → Office 365 with Lucid8's DigiScope

  • Hi Dmg,

    Did you try to restart the information store service ? 

    Here is an similar case for your reference:

    Manually Move Public Folders from Exchange 2010 to 2013

    Solution: finally it was a heavy network issue that it freeze the information store, that always ends in stalledduemailboxlock, so every time it happens I had to restart the information store service and the migration started to work fine again 

    Hope it helps,


    Best Regards,

  • I have tried that. The information store was restarted on all servers just to be sure. This happens almost instanaously. I have moved user mailboxes over just fine that were GBs big. The public folders are relatively small with just a few  calendars. When I try to perform the migration on what server I get the sync source error, when I run it on the other I get the mailbox stall after about ten percent and within a couple of minutes. I followed the said document above to the T. I am stuck at trying to migrate the public folders over.

  • Hi Dmg,

    Try to remove all public folder migration requests and check again:

    Get-PublicFolderMigrationRequest | Remove-PublicFolderMigrationRequest

    If still persists, follow the below steps and clear all move requests, then move again to check if any helps:

    Open regedit on the Exchange 2007 server:

    Navigate to HKEY_Local_Machine > System > CurrentControlSet > Services > Tcpip > Parameters >Create a new D-Word (32 bit) value called 'KeepAliveTime' Set it to 3600000 as Decimal >Exit registry.

    Then, performed similar changes on the Exchange 2013 server 

    Restarted all Exchange services on both of servers.

  • Same issue - what was your final solution. I've tried all of the above as well and still instantly get the sync source mode error.

  • Tried this same error, any other thoughts?

  • There was a different method that Microsoft suggested how to do. The way i was using was not the suggested method after a certain update. I will try to find it but it has been about a year since i solved it.
