since the upgrade to SP2 it is not possible to log in to owa. We found the folling error in the eventvwr: "error trying to load the modul-DLL 'C:\Program Files\Microsoft\Exchange Server\V14\Bin\exppw.dll" (tranlated from German to English)
So we tried to reinstall the CAS-Rolle but we are getting the second error in the program/features: "exsetup can not start directly to excecute upgrades. Use Setup.com".
Is the Server still in the upgradeprocess? What ca we do?
Thank a lot in advance!
