More tools for Exchange accounts
If you use a corporate Microsoft Exchange account, Mail has some tweaks just for you that are smaller but still much needed and very welcome.
The availability will depend upon what your administrator has enabled, but there are more options to be found in the Advanced Settings.
You can use S/MIME, which adds higher-level encryption to messages. Messages from outside-the-organization can be marked in red if you want to step up your security. There is also an option for auto-reply messages, though again this takes some work on the back end by your IT department.
