I’d love to say it’s simple to get started, but if you use the version of Outlook that I use - Outlook 2013 - you’ll need to navigate a rabbit’s warren of clicks and commands. It’s come to my rescue many a time, allowing me to pop into my outbox and fix inaccuracies add the PowerPoint file I forgot to attach or re-edit a sensitive message for nuance.
It’s for these sorts of reasons that several years ago I decided to put a two-minute delay on all of my office emails. Don’t let poorly-crafted communications hold you back.
