A feature that is the best part of MailButler for me is where if I send an email with a follow up MaiButler automatically creates an entry in my Microsoft “To Do” app on the date specified for follow up. I then can go in to the app and click on a hypertext link which MailButler has established and it used to take me directly to the email that I needed to follow up. Now, before the email is opened, it takes me to a webpage and forces me to select “Open Mail.app”. This did not happen in the past and seems like an unnecessary step.
