Microsoft Office Outlook Alternatives
Microsofts Office Outlook is one of the most used software in the world. It's of course most famous as a e-mail client but it can do much more.

Maybe Calendar Integration or a built in RSS-feed support is important to you. Also remember that you can browse other apps as well if you for example looking for a dedicated todo-manager or a RSS reader.

Fast and User friendly. Light-weight and classic menus really give a touch of old classic office 2003. Easy integration of mails especially exchange mails without facing any bottlenecks.Support for EWS allows me to connect to exchange and get all the benefits like contacts and calendar I wouldn't so easily get on Thunderbird. Also it nicely integrates with the built in Ubuntu calendar as well which is a big plus.I've found it better than thunderbird and it can work with exchange just with one free plugin - Open source Android email client with support for multi-folder sync, keyboard shortcuts, and more.

Ease-of-use, simple setup, already installedvirtueisitsownreward Lots of limitations a la Apple's usual attempts to protect users from themselves. E.g. you can choose one default send-from address, or let Mail choose, and the choices it makes are useless. You can't just click on one of your mailboxes, create a new email, and have it always send from the mailbox you chose. Also no way to turn off in-line attachments so you can attach files the way literally every other email client does.Outlook is an all-in-one solution including mail calendar etc. this soft does only one thing - Geary is an email application built around conversations, for the GNOME 3 desktop.
