Hello, thanks for this very good article, it was exactly what i was looking for. My old server sends the backfill response and it is received on the new e2k7 smtp but according to exchange message tracking it fails with:
554 5.6.0 STOREDRV.Deliver; Corrupt message content
or
554 5.6.0 STOREDRV.Deliver.Exception:ObjectValidationException; Failed to process message due to a permanent exception
So the debugging steps you described helped me futher. Here is what I get from ContentConversionTracingInboundFailures:
Microsoft.Exchange.Data.Storage.ObjectValidationException: The object is invalid and cannot be saved.
at Microsoft.Exchange.Data.Storage.StoreObject.ValidateStoreObject()
...
Any ideas what might cause the exception? Or how do I futher investigate this?
As a solution to other cases you suggest to edit the items on the old server. How exactly should we gain access to these items? Outlook shows me the pf store on the new server. Should I make a temporary account into the mailbox store of the old server and reassociate this mailbox store with this public folder store?
Thanks in advance!
