• Create a new contact, task, note, journal entry, or appointment
• Change any configuration in the Outlook Web Access options folder

RESOLUTION

This Microsoft Exchange Server hotfix resolves the three issues that are mentioned in the "Symptoms" section. This hotfix enables a new editor for Internet Explorer. The new editor uses an Internet Explorer "iframe" instead of an ActiveX control. After you apply hotfix 911829, you are not required to first click in the compose frame in Outlook Web Access before you edit text.

Important For this resolution to work, you must apply the hotfix to both the front-end server and to the back-end server.
