When this feature is enabled, users can view attachments as HTML. If this feature is disabled, users can only view attachments if they have the appropriate application on their computer.
The ability to view email attachments as HTML can be enabled in global settings, Class of Service, or accounts.
You can configure accounts to be able to view attachments only in HTML or to have the option to view either in the original format and as HTML. Opening an attachment can be faster than opening the original format.
If Attachments are viewed in HTML regardless of COS is enabled in Global Settings, all accounts can view attachments only in HTML. If this feature is not enabled as a global setting, the Account attachment setting overrides the COS attachment setting for that account.
Do one of the following:
Open the user account; go to the Advanced tab
Click the Class of Service to edit and go to the Advanced tab
Select either Attachments may be viewed in HTML only, or Attachments may be viewed in HTML and their original format.
Click Save.
