As a software it is very good option. Nice looking UI, user friendly, good email management, directly integrated in Microsoft office.

What I like the best about Outlook is the ability to integrate so many other Microsoft programs like Teams and To Do. If I flag an email, it shows up in To Do as a task to go back to.

The best thing about outlook is, the ease of use and the professionalism of the costumers service.

The worst part I would say however is the app. They developed an app for the apple store and quite honestly it is slow and very difficult to navigate around compared to the desktop version.

Scientist 1

Good product overall for workplace solutions. The integration with other office tools really helps.

I can even add an image to my signature which is a very attractive feature. The customer care team were very responsive when I had a problem last year.

Crash , no easy access from my phone , new emails update rate , older emails storage , retriving the older emails or lost emails is a big deal.

The interface has too much going on. There are a lot of useless features that i needed to turn off.

Student 

I dislike the difference in the email interface when emails are from external users.

Great tool for basic business needs for the price paid.

Reliable, stable Software, fast, and gets continuously improved.

When I contacted the support, I was asked to paid 8$ to get assistance. I bought a lifetime licence and now I am stuck with a broken software.

I like the theme option with the software and the ability to organize accounts groups as well as folders etc easily on the fly.
