I'm forced to use MS-Outlook in my job, while I very much like the feature that shows all the messages of a discussion thread (that are stored in different folders) in the inbox when a new message is received for that thread, if the previous messages are in a different data file (which I'm forced to have as the MS-Exchange server quota is very very small) then the message list only shows the name of the data file and not the name of the folder where the messages are stored.

As a result, because I file my message by context (i.e. all the emails for project A go into a "Project A" folder, etc), and its important for me to have all the messages in a single thread in the same folder, it is sometimes hard to figure out into which folder should I file the new message.

It would be great help if there was some add-on or VBA script that I could add to my setup that will offer a shortcut key or a button to "file this message to the same folder as the previous messages in the conversation thread".
