Pros / Cons
  • Overall, Outlook is a solid, dependable email and productivity platform that’s well-suited for professional and business use. While it has a learning curve and occasional performance issues, its reliability, integration, and organizational tools outweigh its drawbacks.
  • It also has a few glitches with showing read vs unread emails and the number of unread emails icon on mobile doesn’t update in real time.

  • I am able to work over multiple email boxes, be quick in my responses (as a quick reply option!) and i can change my email signatures with ease.
  • Furthermore, I use it strictly for emails - so no Task Management, Chats, Grouping, etc. that is included in many other tools (but which I don't need).
