Paperclip icon present on the message with no attachments


Sometimes CodeTwo Exchange Rules users are facing the problem where a attachment icon (a paperclip symbol) is visible on the list of messages right next to the email but it actually contains no attachments at all (Fig.1.). This might be caused by the way OWA (Outlook Web Access) client treats hidden attachments.

When the user creates a signature in CodeTwo Exchange Rules that contains pictures, they are placed in the message, as hidden attachments. OWA changes the properties of such attachments, and "un-hides" them. In other words - if the message that was stamped with the signature by CodeTwo Exchange Rules is opened/replied/forwarded in OWA then it will appear in Outlook as the one that contains attachments.


Unfortunately, there is currently no solution to fix this problem - it stems from the OWA client architecture and the way it reads/writes messages.
