Hi, We noticed the following problem with version 1.0.3 and 1.0.4 of the Outlook Plug-in All machines are WindowsXP SP2 all latest patches All machines are Office 2003 SP1 all latest patches Scenario User logs into windows User opens Word or any application that supports the Send-To feature User sends an email using the Send-To As Attachment feature. Message is delivered Try to send a second attachment Error "Operation Failed" Look in Task Manager - there are two OUTLOOK.EXE process' running. The first process did not end gracefully when the first message was sent. For some reason the two processes are causing a problem that prevents messages from being delivered from an external application. Disable the Spambayes COM Add-In within outlook and the OUTLOOK.EXE process ends gracefully every time. Scenario 2 User logs into Windows Opens Outlook Opens Word Uses the Send-To As Attachment feature User can send documents all day long provided they don't close Outlook. Every indication points to the Spambayes program causing the Operation Failed error. I haven't been able to reproduce this with 1.1a1 Is this a known bug in the older versions? Thanks. Robert Mezzone
