I absolutely love the app Boomerang for Gmail. It made me so much more productive. Unfortunately, at work I'm on outlook (part of Office 365 Business) and Boomerang is not available for that. Boomerang for Outlook exists but only works in the web app with an outlook account.

E-mail reminders (email returns after x days without reply) Return an email to your inbox at a a specific time (snooze email) Mailbox Pauze Send later ...
Is there an alternative that works with Outlook?
