Email with no attachments is displayed with the paperclip icon
Sometimes recipients of messages stamped with signatures created in CodeTwo Exchange Rules see an attachment icon (a paperclip symbol) even though the message contains no attachments. The paperclip icon appears on the list of messages, right next to the message's subject line (Fig. 1.).
The attachments icon might appear unnecessarily due to the way OWA (Outlook Web Access) processes hidden attachments. When you create a signature with images in CodeTwo Exchange Rules, these images are added to messages as hidden attachments. OWA changes the properties of such attachments and unhides them. If the message stamped with signature by CodeTwo Exchange Rules is opened / replied to / forwarded in OWA, the message is displayed as if it contained attachments.
Unfortunately, there is currently no fix to this problem, as it is caused by the OWA's architecture and the way OWA processes emails.
