Microsoft Outlook may warn that messages contain potentially unsafe attachments after attachments have been removed.

Applies To:

E-mail Management Server 2006

Conditions / Symptoms

If the ‘keep paperclip icon’ feature is turned on, Microsoft Outlook may report in messages that have had attachments removed, “Outlook blocked access to the following potentially unsafe attachments:”.  The attachments listed will have the file extension “.lnk”. 

Issue / Cause

In order to keep paperclip icons on messages after attachments have been moved, E-mail Management Server places very small shortcut link files in the messages.  These link (“.lnk”) files are the same as shortcuts you might create on your desktop. 

Work Around / Fix

No work around or fix is required.  This is normal behavior.
