Microsoft Outlook vs Zoho Mail: Which is best for you?

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.

They offer quite a few features (mail - with all the features you'd find in GMail or other big providers, calendar, to do lists / task boards etc.)

Think about where your users store the recovery codes and you see that you may create a weakness in the security - voids the point of 2FA in some ways (some not all).
