To resolve this issue, install Hotfix Rollup 5 for Antigen 9.0 with Service Pack 1. For more information, click the following article number to view the article in the Microsoft Knowledge Base: Note

• You must install Antigen 9.0 for Exchange with Service Pack 1 before you install Hotfix Rollup 5 for Antigen 9.0 with Service Pack 1.
• There are two hotfix rollup packages available. One is for stand-alone server only. The other is for clustered environments only. If you are running a clustered environment, you must install the full install package instead of the rollup-only package.
