Firstly, I am not a notes admin - but a user of Notes and of a Blackberry linked to my Notes mail and Calendar. I am asking the question as a user to know if this is doable.
When you first are setup for a Blackberry - its email folders are all empty. As emails come into your inbox and are filed they are stored on the blackberry and can be filed using the method above. However existing emails in your notes client view which may be filed in folders are not available on the Blackberry. I would like to know if there is a way to push these filed emails (say the last 6 months worth) down to the Blackberry email folders.
