1) The msg being left in the "Work In Progress" folder offers a few support problems:
a) user will complain they have an unexpected copy of an email (which one is the original? will they save it twice?)
b) it uses up the mailbox quota and requires the user to clean up (thats hard enough getting them to do already)
2) When opening a 2nd saved to 'internet mail' message which has been saved as an .eml it opens the message over the top of the 1st message - it appears to display HTML content in my case and is very confusing to the average user, not ideal if you want to open many emails saved out in the past and collate information from each.
So in summary its definately a step in the right direction but at this time its not a robust enough tool to be used in a production environment such as my workplace - oh well better get back to my exchange plan - if only Novell would just give this functionality out of the box with GW !
