Do you need to select the archive database explicitly for Retain to archive messages stored in the Exchange userâs archive folder?
No, you do not as long as you have selected to Include userâs archive mailbox in Profiles/Miscellaneous.
With that option enabled Retain is able to query Exchange such that it will be given access to the archive database. Any unarchived messages in the Exchange archive folder will be placed in an Archive folder in the userâs Retain mailbox.
If you choose only the archive database, the main Exchange mailbox will also be archived.
You may choose both the main database and the archive database in setting up the Retain job but that may effect performance.
