Moved a bunch of mailboxes over to Exchange 2010 from 2003 and only one failed, but I can't figure out why it keeps failing.
This is the error that it gives:
Error: MapiExceptionPermanentImportFailure: Data import failed --> MapiExceptionInvalidParameter: IExchangeFastTransferEx.SetProps failed (hr=0x80070057, ec=0)
There were a bunch of other mailboxes that moved over perfectly, only this one is giving me problems. Anyone know what this error is?
