Outlook lets you make your own custom rules (like always send emails from x to this folder, and so on).You can also share or assign tasks (like a to-do) with your coworkers, and you can also share your calendar with them.You can create new meetings/tasks/contacts right from inbox (no switching windows involved).

Here are some of Outlook’s other best selling points: Many large companies use Outlook for their email, and it offers robust calendar, task manager, and other customizable features. It's not quite as simple to use as Gmail, for example, but you can do more with it. If you're looking for a powerful email service that offers tons of features plus the ability to integrate with a bunch of business-friendly applications, Outlook is a good option for you. If you want to create a Gmail account, you can do so here. So if you have multiple gigabytes of photos on your computer in Google Photos, you might strain your email storage capabilities. Now while that sounds like a lot, keep in mind that it's used by Google Photos, Google Drive, and any other Google tools you use as well. Storage: Gmail gives you 15GB of free storage. Some other cool features? Customize the amount of time you have to undo sent emails, auto-advance through your inbox (under the Advanced tab in Settings), Offline mode, and dragging email between tabs.It also has 'Confidential mode' and you can set expiry times on your messages. Gmail has good security, and you can send/receive money through your email.

In addition to regular search functionality (by folder, and so on), you can also find emails by date (type before:date – like – and it’ll search in just those messages).

There are advanced search options available (just click the down arrow on the right of the search bar).

Use the reading pane feature so you can see your inbox and the email you're reading at the same time (just go to Settings - Reading Pane - and choose where you want it).

You can use smart compose (like auto-complete) to help you write your emails faster – and you can even translate your message right in Gmail (under the three dots - 'Translate message').You can email large attachments through Google Drive (and save docs there so they don't clutter up your local computer).

You can schedule emails to send at a certain time, snooze them so you don't lose track of them, and customize your notifications.
