Microsoft does not have a official Outlook email client for GNU / Linux, although yes for Android. For the moment, if you want to use something similar, you have to be content with Prospect Mail, an unofficial client for this email platform.
Another option is to use the great alternatives of existing email clients natively for your distro, in addition to being open source and free, and that can also be configured to use Microsoft email accounts without any problem. In this article you will be able to know the 3 most recommended:
- Thunderbird: is one of the best known and most used clients for Linux. It was created by Mozilla, although it would later be released and is now maintained by the community. This email client is really exceptional, and very versatile. It allows to have a professional, efficient, highly customizable, feature-rich, and simple email manager for both beginners and advanced users. It has support for a huge number of mail services both normal and business.
- Evolution- This other email client has also ranked among the best and the favorite of many users. It is a manager created under the GNOME project and in which you can have an integrated package manager, along with an agenda, calendar, etc., all in a single software. A fantastic way to manage workgroups, always keep your tasks in mind, and communicate with whoever you want. Also, it supports Exchange Server.
- Contact: this service comes from the KDE project. It is a very powerful and manageable manager, with an email client, calendar, contacts and other functions. Very feature-rich for email and with support for many protocols. Its interface is also very clean and simple. By the way, both Evolution and Kontact can be installed in all desktop environments ...
Thunderbird is the best option, I have 2 years full linux, and it really is the one I recommend the most.
It was necessary to add vivaldi with its mail manager, which although it is in beta phase is doing quite well
Well, I installed the outlook.com email account in the sylpheed client and it works perfect
