Composing and sending your first email in Outlook is simpler than you might expect with the built-in tools available. Whether you use Outlook for work, school, or personal communication, learning how to send email on Outlook is a basic skill that saves time and keeps you organized. This guide walks you through every step, from opening the app to attaching files and managing sent messages.
Outlook comes in several versions—desktop, web, and mobile—but the core process stays the same. You click a button, fill in the fields, and hit send. Let’s break it down so you can start sending emails with confidence.
How To Send Email On Outlook
To send an email in Outlook, you first need to open the application and sign in to your account. The exact steps vary slightly depending on whether you use Outlook 2019, Microsoft 365, Outlook on the web, or the mobile app. But the main idea is identical: create a new message, address it, write your content, and send it.
Step 1: Open Outlook And Sign In
Launch Outlook on your computer or open the web version at outlook.com. Enter your email address and password if prompted. For desktop users, Outlook usually opens to your inbox automatically after sign-in. If you use a work or school account, you might need to enter your organization’s credentials.
Step 2: Click The New Email Button
Look for the “New Email” button in the top-left corner of the ribbon menu. In Outlook on the web, it says “New message” instead. Clicking this opens a blank email window where you can compose your message. On mobile, tap the compose icon, which looks like a pencil or a plus sign.
Step 3: Fill In The Recipient Fields
In the new message window, you will see several fields. The “To” field is where you type the recipient’s email address. You can enter multiple addresses separated by semicolons. The “Cc” field is for carbon copies—people who need to see the email but are not the primary recipient. The “Bcc” field hides recipients from each other. Use Bcc for privacy when sending to a group.
- To: Main recipient(s)
- Cc: Secondary recipients (visible to all)
- Bcc: Hidden recipients (not visible to others)
If you have saved contacts, start typing a name and Outlook will suggest matching addresses from your address book. This speeds up the process and reduces typos.
Step 4: Add A Subject Line
The subject line should briefly describe the email’s purpose. Keep it clear and concise, like “Meeting Agenda” or “Invoice Attached.” A good subject helps the recipient understand the email’s importance and makes it easier to find later. Avoid leaving the subject blank, as that can look unprofessional or get flagged as spam.
Step 5: Write Your Message
Click inside the large message body area and start typing. Use short paragraphs and bullet points for readability. Outlook includes a formatting toolbar where you can change fonts, add bold or italics, create lists, and insert hyperlinks. Keep your tone friendly but professional. Proofread before sending to catch mistakes.
If you need to include a signature, Outlook can add one automatically. Go to Settings > Mail > Signature to set this up. A signature typically includes your name, title, and contact information.
Step 6: Attach Files Or Images
To attach a file, click the paperclip icon in the toolbar or select “Attach File” from the Insert menu. Browse your computer or cloud storage (OneDrive, Google Drive) and select the file. Outlook supports most file types, including PDFs, Word documents, and images. For large files, consider using a link instead of an attachment to avoid size limits.
You can also insert images directly into the email body. Click “Insert” > “Pictures” and choose your file. This works well for photos or logos that should appear inline with your text.
Step 7: Send The Email
Once everything is ready, click the “Send” button at the top-left of the message window. Outlook moves the email to your “Sent Items” folder. If you change your mind immediately after sending, you can recall the message in some versions, but this feature is not always reliable. Double-check the recipient, subject, and attachments before clicking send.
After sending, Outlook may show a confirmation message. You can also set a delay for sending emails by using the “Delay Delivery” option under the Options tab. This is useful if you want to schedule an email for later.
Common Outlook Versions And Their Differences
While the basic steps are the same, each Outlook version has slight variations. Here is a quick breakdown for the most common platforms.
Outlook Desktop (Microsoft 365 And Office 2019)
The desktop app offers the most features. You can customize the ribbon, set rules for automatic sorting, and use advanced formatting. The “New Email” button is in the Home tab. Attachments are added via the Insert tab. This version also supports offline composing, meaning you can write emails without an internet connection and send them later.
Outlook On The Web (Outlook.com)
The web version is free and works in any browser. Click “New message” in the top-left. The compose window appears as a sidebar or pop-up. Attachments are added via the paperclip icon. One advantage is that you can easily access OneDrive files without downloading them first. The web version also integrates with other Microsoft services like Teams and Calendar.
Outlook Mobile App (IOS And Android)
The mobile app is designed for touch screens. Tap the compose icon (usually a pencil or plus sign) at the bottom. The interface is simplified but includes all essential fields. You can attach photos from your gallery or cloud storage. Voice typing is available on some devices. The mobile app also supports swipe gestures to delete or archive emails quickly.
Tips For Sending Emails Efficiently In Outlook
Once you master the basics, you can use these tips to save time and avoid common mistakes.
Use Keyboard Shortcuts
Keyboard shortcuts speed up email composition. In Outlook desktop, press Ctrl+N to create a new email. Ctrl+Enter sends the message. Ctrl+K checks names in the address fields. On the web, shortcuts are similar but may vary by browser. Learn a few shortcuts to reduce mouse clicks.
Set Up Quick Parts Or Templates
If you send similar emails often, create a template. In Outlook desktop, compose a message, then go to Insert > Quick Parts > Save Selection to Quick Part Gallery. You can reuse this text later. For the web, use the “My Templates” add-in to store canned responses. This is great for repetitive replies like meeting confirmations or status updates.
Check Spelling And Grammar
Outlook includes a built-in spell checker. It underlines misspelled words in red. Right-click to see suggestions. You can also run a full check by clicking Review > Spelling & Grammar. Enable automatic checking in Options > Mail > Spelling. This catches typos before they reach the recipient.
Use The Delay Send Feature
To avoid sending an email at an awkward time, set a delay. In Outlook desktop, click Options > Delay Delivery. Choose a date and time. The email stays in your Outbox until that moment. On the web, you can schedule send by clicking the dropdown arrow next to the Send button and selecting “Send later.” This is useful for working across time zones.
Organize With Folders And Rules
After sending, you might want to track replies. Create folders in your mailbox to sort sent emails. You can also set up rules to automatically move or flag messages. For example, create a rule that moves all emails from your boss to a “Priority” folder. This keeps your inbox clean and helps you find important messages quickly.
Troubleshooting Common Issues When Sending Emails
Sometimes emails do not send as expected. Here are solutions to frequent problems.
Email Stuck In Outbox
If your email stays in the Outbox folder, it usually means Outlook cannot connect to the server. Check your internet connection. In desktop Outlook, click the Send/Receive tab and select “Send All.” For the web, refresh the page. If the problem persists, restart the app or check your account settings for incorrect server details.
Attachment Size Limit Exceeded
Outlook limits attachments to 20-25 MB depending on the version. If your file is larger, compress it into a ZIP folder or use a cloud link. In Outlook desktop, you can insert a OneDrive link by clicking Attach File > Browse Web Locations. This bypasses the size limit and lets recipients download the file from the cloud.
Recipient Not Receiving The Email
If the recipient says they did not get your email, check the “Sent Items” folder to confirm it was sent. Verify the email address is correct. Ask them to check their spam or junk folder. If you use Bcc, remember that those recipients are hidden, so they might not appear in the sent message. Also, some corporate firewalls block external emails.
Email Sent To Wrong Person
Mistakes happen. If you sent an email to the wrong person, try to recall it. In Outlook desktop, go to Sent Items, open the message, and select “Recall This Message” from the Actions menu. This only works if the recipient has not opened it yet and uses the same Exchange server. For the web, recall is not available, so you may need to send a follow-up apology.
Advanced Features For Power Users
Once you are comfortable sending basic emails, explore these advanced options.
Using Mail Merge With Outlook
Mail merge lets you send personalized emails to a list of recipients. You need Word and Outlook together. Create a list in Excel, then use Word’s Mailings tab to insert merge fields. Complete the merge to Outlook and send individual emails. This is ideal for newsletters or bulk announcements.
Setting Up Automatic Replies
When you are away, set an automatic reply. In Outlook desktop, go to File > Automatic Replies (Out of Office). Choose a date range and write your message. On the web, click Settings > View All Outlook Settings > Mail > Automatic Replies. This sends a response to everyone who emails you, letting them know you are unavailable.
Encrypting Sensitive Emails
For confidential information, use encryption. In Outlook desktop, click Options > Encrypt. Recipients need a digital ID to read the message. On the web, use the “Encrypt” button under the Options menu. This protects the email content from being intercepted. Check with your IT department if encryption is required for your work.
Frequently Asked Questions
Can I send an email to multiple people without them seeing each other?
Yes, use the Bcc field. Add recipients there, and their addresses will be hidden from other recipients. This is useful for mailing lists or group announcements.
Why does my email show as “Unsent” in Outlook?
An unsent status usually means the email is still in your Outbox. Check your internet connection and click Send/Receive to push it out. If it remains, verify your account settings are correct.
How do I send a email with a high importance flag?
In the new message window, click the “High Importance” icon (exclamation mark) in the toolbar. This adds a red flag to the email, alerting the recipient that it is urgent. Use this sparingly to avoid desensitizing readers.
Can I schedule an email to send later in Outlook?
Yes, in Outlook desktop, use the Delay Delivery option under the Options tab. On the web, click the dropdown next to Send and choose “Send later.” Pick your desired date and time.
What is the maximum number of recipients I can add to one email?
Outlook limits the To, Cc, and Bcc fields combined to around 500 recipients for most accounts. For larger lists, use a distribution group or mailing list service to avoid hitting limits.
