Exchange 2016 and Outlook 2010 scenario.
I currently have in production the Exchange in-place archiving for all users and have set the default 1 year to move to archive and user's archives folder structure is visible in their Outlook.
I now want to change the default to 3 years without effecting user's current archives and not sure how to do this without affecting current folder structure. I want to make it completely transparent to the users.
Thanks in Advance
