I have found a solution that we have implemented with each user's outlook from the following question:
Going forward if we want to make changes we will now have to go and edit each users VBA code. Is there any way to have some code that would check for a file in a public file location and "update" the code? Say if we wanted to add/edit some conditions from the original code, or perhaps have the code check some sort of text table to determine conditions to check for? This would permit multi user changes without having to edit Outlook's VBA code for each work station.
