new Server, Did clean install of Windows 2012 Server, followed by all updates. Then installed Exchange 2010 SP3. Installed additional updates. Configured Exchange 2010 SP3 as part of an existing Exchange 2007 environment. Prior to new Server, Exchange 2007 (latest rollup) running on Windows 2008 Server, with no problems.
New Server now seems to be running fine, except the Queue Viewer keeps giving error with the following message:
Cannot process argument transformation on parameter "BookmarkObject". Cannot convert the "Microsoft.Exchange.Data.QueueViewer.PropertyBagBasedMessageInfo" value of type "Deserialized.Microsoft.Exchange.Data.QueueViewer.PropertybasgBasedMessageInfo" to type
in the queue viewer, some (not all) emails get stuck in the submission queue with the error
"A storage transient failure has occurred during content conversion."
not sure if the two are related.
I have stopped the transport service, deleted the messages from the directory that holds the messages in the queue (C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\data\Queue)
restarted transport service. But, then more emails get stuck with the same error.
