CAUSE

This issue occurs when the following conditions are true:

  • An Exchange Server 2003 hotfix or update package that contains the Microsoft.Exchange.OMA.UserInterface.dll file is installed.

WORKAROUND

To resolve this problem, manually replace the Microsoft.Exchange.OMA.UserInterface.dll file. To do this, follow these steps:
  1. Download the English version of the hotfix, and then unzip the package.
  2. Extract the Microsoft.Exchange.OMA.UserInterface.dll file. To do this, open a command prompt, type the following command, and then press Enter:
    Exchange2003-KBxxxxxx-x86.exe /x
    In this command, xxxxxx is the Microsoft Knowledge Base (KB) article number that describes the hotfix.
  3. Copy the Microsoft.Exchange.OMA.UserInterface.dll file that you extracted in step 2 into the following folder:
    \Exchsrvr\OMA\browse\bin
