Composing Your First Email in Outlook
Starting a New Message
To begin, click New Mail on the web, the New Email button on the desktop, or the compose icon on mobile. The message window opens with standard fields including To, Subject, and body area.
Adding Recipients and Details
Enter email addresses in the To field, and use Cc for secondary recipients or Bcc for privacy. Type a clear subject line and add context in the message body, formatting as needed with bullets, bold, or italics.
Sending Messages with Confidence
Review Before You Send
Check recipients, subject, and tone before sending. Use the reading pane or open the message in a separate window to confirm links, attachments, and formatting.
Using Delay and Rules
Schedule send times with Delay Delivery to align with working hours or peak engagement. Apply simple rules to organize outgoing mail and reduce errors.
Tracking and Managing Sent Items
Enable read receipts when appropriate and verify that sent items are filed correctly. Use categories and search folders to manage large volumes of sent messages efficiently.
Customizing Outgoing Email Settings
Default Signature and Formatting
Set a professional signature in Settings or Options so it appears automatically. Choose font styles, colors, and image handling preferences to match your brand.
Encryption and Security Options
Use encryption and sensitivity labels to protect confidential information. Control external sharing settings to manage who can reply or forward your messages.
Troubleshooting Common Delivery Issues
Checking Outbox and Errors
If a message stays in Outbox, review error prompts, verify account connectivity, and ensure SMTP settings are correct. Retry send or resend after correcting identified issues.

Compress images and use OneDrive links for large files to avoid delivery problems. Confirm that attachments are under size limits and not blocked by policy.
