Hello Exchange Experts, I am hoping you might be able to provide some good stuff for someone new to the environment.
We are running Exchange 2013 in our school district. We mainly have users on Macs with Outlook 2011, Outlook Web App, and some on the PC version of Outlook (2010, 2013 Primarily) We have our head secretary that sends out an email to all users through a Dynamic Group titled "News" that tend to be quite large due to pictures inserted. They aren't necessary to retain and I would like to have them auto-delete after a month or so. What is the best method of creating a rule set or something entirely that would cause these items to be purged?
We have a lot of boxes that are created for Substitute teachers which are never accessed. This causes a plethora of email that is simply just garbage.
