Learning how to use Outlook opens the door to more than just email. Microsoft Outlook combines your inbox, calendar, contacts, and tasks in one place, which is why it is the standard tool at millions of workplaces and schools in 2026. Whether you are using the free web version at outlook.com, the new Outlook app on Windows and Mac, or the mobile app on your phone, the core layout and features are the same.
This beginner guide focuses on the essentials you will actually use every day: opening and reading messages, replying and composing new email, organizing your inbox with folders and categories, and scheduling events on the calendar. We will keep the language plain and point out exactly where each button lives so you never feel lost inside the app.
Getting to know the Outlook layout
When Outlook opens, the screen is divided into three main areas. On the far left is a narrow bar of icons that switch between Mail, Calendar, People (contacts), and To Do. Next to it is your folder list, showing Inbox, Sent Items, Drafts, Junk Email, and any folders you create. The large area on the right is the reading pane where messages appear.
The Focused and Other inboxes
Outlook often splits your inbox into two tabs: “Focused,” which holds important messages, and “Other,” which collects newsletters and low-priority mail. If a message lands in the wrong tab, right-click it and choose “Move to Focused” or “Move to Other” to train the system. You can also turn this feature off in Settings if you prefer one single inbox.
Step-by-step: reading and sending mail
These core actions are the heart of Outlook. Once you have them down, everything else builds on top.
- Sign in. Go to outlook.com or open the Outlook app and enter your Microsoft account email and password.
- Open a message. Click any email in the message list; it appears in the reading pane on the right.
- Reply or forward. Use the Reply, Reply All, or Forward buttons at the top of the open message.
- Start a new email. Click “New mail” in the top-left corner to open a blank compose window.
- Fill in the details. Add recipients in the To field, write a subject, and type your message.
- Attach files. Click the paperclip or Insert menu to add documents, photos, or files from OneDrive.
- Send. Click the Send button, and a copy is stored in your Sent Items folder.
Organizing your inbox
Outlook shines at keeping mail tidy. You can create folders to sort messages by project or sender, apply colored categories, and set up rules that automatically file incoming mail. To make a folder, right-click “Folders” in the left pane and choose “Create new folder,” then drag messages into it.
Archiving moves a message out of your inbox into an Archive folder without deleting it. Use it for mail you want to keep for reference but no longer need front and center. You can always search it later.
Rules automate your inbox. For example, a rule can send every message from your bank straight into a “Finances” folder. Set them up under Settings, then Mail, then Rules to save time each day.
Using the Outlook calendar
The calendar is one of Outlook’s biggest advantages over basic email apps. Click the calendar icon on the left to switch views, then double-click any date to create an event. You can invite others, set reminders, and mark yourself busy or free so colleagues can see your availability.
| Feature | What it does |
|---|---|
| New mail | Opens a blank email to compose and send. |
| Calendar | Schedules events, meetings, and reminders. |
| People | Stores contacts and their details. |
| Folders | Organizes messages by topic or sender. |
| Search bar | Finds any email, contact, or event fast. |
| Categories | Color-codes messages for quick sorting. |
Outlook on the web vs. the desktop app
The web version at outlook.com needs no installation and works in any browser, which is ideal for beginners or shared computers. The new Outlook desktop app for Windows and Mac offers the same clean design plus offline access, so you can read and draft mail without an internet connection. Both sync automatically, so a message read on one appears read on the other. To keep building your skills, check out more of our how-to guides.
Frequently Asked Questions
Is Outlook free to use?
Yes, the web version at outlook.com and the basic Outlook app are free with a Microsoft account. Advanced features, extra storage, and the classic desktop apps come with a Microsoft 365 subscription, but most beginners are fully covered by the free version.
What is the difference between Outlook and Gmail?
Both are email services, but Outlook is made by Microsoft and integrates tightly with the calendar, Microsoft Teams, and Office apps like Word and Excel. Gmail is made by Google. The core email experience is similar, so choosing between them often comes down to which ecosystem you already use.
How do I add another email account to Outlook?
Go to Settings, choose “Accounts,” then “Email accounts,” and select “Add account.” Outlook can manage several addresses in one place, including Gmail and Yahoo accounts, so you see all your mail in a single inbox.
Why are my emails going to the Other tab?
The Focused Inbox feature sorts less important mail into the Other tab automatically. If something important lands there, right-click and choose “Move to Focused” and, if asked, “Always move.” You can also disable Focused Inbox entirely in Settings.
Can I use Outlook on my phone?
Yes. The free Outlook app for iPhone and Android puts your mail, calendar, and contacts on your phone with notifications. It syncs with the web and desktop versions, so your inbox stays consistent across every device.
