The Mail Security service is stuck in a starting state

The following are the most common reasons that the Mail Security service gets stuck in a starting state:

Spam data is not collected by default

If spam-related data does not appear in reports, ensure that the "Include spam data" checkbox is enabled on the Report Settings page.

Cannot connect to server

One possible cause for this error is if the Domain Controller is running on the same server as Microsoft Exchange. Microsoft acknowledges this as a defect and has provided a manual workaround for this issue.

Unique identifier (UID) errors might occur in Outlook or Outlook Express when using IMAP

This error can occur when the mail client is open on the desktop at the same time a violation is detected on the server. These warnings can be ignored. Refresh the mailbox. Outlook, Exchange, and Mail Security will continue to function normally.

HTTP 500 Internal

An Outlook Web Access user might receive this error in the following circumstances:

This occurs because Outlook Web Access uploads attachments immediately, rather than when the user clicks "send." Mail Security automatically deletes the violating attachment, which results in the upload operation failing.

OWA message: The action could not be completed because of a conflict with the original item

A message sender who is using Outlook Web Access might get the following error message if Mail Security detects a violation:

The action could not be completed because of a conflict with the original item. The conflict may have occurred when an existing item was updated on another computer or device. Open the item again and try making your changes. If the problem continues, contact technical support for your organization.

This issue is a defect in Exchange 2007. There is currently no workaround. For more information, see the Microsoft Web site.

This error only occurs on Outlook Web Access 2007.
