Effect of Virus Scanning on Outlook Web Access

There is an error message that users may receive in Microsoft Office Outlook Web Access for Exchange Server 2007 when an antivirus program changes a message in the Drafts folder.

Resolving the Error

If a message in the Drafts folder in Outlook Web Access is scanned by an antivirus program and triggers a screening rule that causes the message to be modified, the user will receive a warning message when they open the message and try to modify it or send it.

To resolve this issue, instruct the user to save and close the message, and then reopen it and try again.
