What do you like best?
I love that outlook has an integration into virtually every business product I use. From my CRM, company chat, virtual meeting, scheduling, marketing, and more - all fit into outlook.
What do you dislike?
While very likely my PC's fault, I tend to have to restart my outlook every week or so because of updates or outlook crashing, so that can be a bummer, but it tends to be 30 seconds to a minute maximum. Just enough time to grab a coffee.
Recommendations to others considering the product
Honestly, I would recommend taking an outlook class. It seems absurd to have to take a class on your email/calendar/task software, but Outlook can do so many things that I didn't know it could do, and I think for me at least, I could benefit from taking an outlook class yearly.
What business problems are you solving with the product? What benefits have you realized?
It makes tracking communication really easy. I'm a big fan (and user) of all of the tasks and folder capabilities, and I very much appreciate that you can set up rules to automatically tag things or send them to different folders.
