Hello,
We also had the problem of the "empty sent items". After reading and searching, it seems that the the sollution was to remove the Update Rollup 6 for Exchange Server 2010 Service Pack 2 (KB2746164).
But if i want to remove the update ( i simply do this by going to the control panel - programs - en there uninsall the update), it wont pull true. Half way i get the messege that i have to sellect the "exchangeserver.msi". If i select the exchangeserver.msi from the installation disk, it doesnt accept is.
What am i doing wrong??
Thanks!!
