Thanks for the reply. We do not currently have an archiving solution, such as ArchiveToGo or GWAVA Retain, and the native GroupWise archiving is disabled for the majority of users. However, we need to allow certain users the ability to archive messages into personal archives.

    I am developing an applet that will run once daily on GroupWise startup and move messages exceeding a specified age (and other conditions such as folder, read/opened etc) to a central archiving server. The code includes a check to establish if there is an existing archive, so I need to know the FID for the mailbox so that I can build the archive folder name (of***arc), where *** is the FID.
