Outlook is the email app I use daily for work. It started as just email but Microsoft turned it into a full workspace – email, calendar, tasks, contacts, and now Copilot AI. Worth learning beyond just opening and sending.
Here's the core features that make Outlook actually useful.
Set up Outlook
Open Outlook on desktop, mobile, or web (outlook.live.com). Sign in with your account – work or personal email.
Outlook supports any email provider via IMAP/POP. But it works best with Microsoft 365 (Exchange) and Outlook.com accounts. Gmail and Yahoo work but with some feature limitations.
Compose and send email
Click New mail top left. Enter recipient address. Type subject and body. Click Send.
Shortcuts to know:
- Ctrl + N – new email
- Ctrl + Enter – send
- Ctrl + R – reply
- Ctrl + Shift + R – reply all
- Ctrl + F – forward
Learn these. Way faster than clicking buttons for every email.
Use folders to organize
Right-click your Inbox in the sidebar. Pick New folder. Name it something useful – Projects, Clients, Receipts, etc. Drag emails into folders to organize.
Don't go crazy with folders. 5-10 useful ones beat 50 ones you forget exist. Search works better than folders for most cases anyway.
Create rules to automate
Right-click any email > Create rule. Outlook offers to filter future emails like this one. Pick conditions and actions:
- Move emails from a specific sender to a folder
- Mark as read automatically
- Flag for follow-up
- Delete forever (for known spam)
- Forward to another address
Rules save hours over time. Set up a few for newsletters, client emails, or specific topics. Outlook processes incoming emails automatically.
Use Calendar
Outlook's Calendar lives in the same app. Click the calendar icon in the bottom left of the sidebar.
Create events with New event. Invite attendees by typing emails. Outlook shows their free/busy status automatically if they're in your organization – useful for finding meeting times.
Share your calendar by right-clicking it > Sharing permissions. Useful for coordinating with colleagues without back-and-forth emails.
Out of office responder
Going on vacation? Set up auto-reply. File > Automatic Replies in classic Outlook. Or Settings gear > Account > Automatic replies in new Outlook.
Set the date range, write a short message, save. Anyone emailing you during that time gets the auto-reply once. Inside-organization and outside-organization messages can be different.
Use tasks and flags
Flag emails for follow-up. Right-click an email > Flag. Pick today, tomorrow, this week, or custom.
Flagged emails show in the Tasks view (To Do icon in sidebar). Acts as a quick reminder system without leaving the inbox.
For full task management, use Microsoft To Do which integrates with Outlook tasks. Add detailed tasks, due dates, reminders.
Focused Inbox
Outlook tries to separate important emails from newsletters automatically. The Focused tab shows what Outlook thinks is important. Other shows everything else.
Right-click any email and move to Other or Focused to teach Outlook. Within a few weeks, the algorithm gets pretty accurate at filtering important emails for you.
Some people love Focused Inbox, others hate it. Disable in View > Show Focused Inbox if you want to see everything together.
Schedule send
Write an email now but send later. Useful for after-hours work without disturbing recipients or hitting time-zone-appropriate windows.
Compose your email. Click the dropdown arrow next to Send. Pick Send later or Schedule send. Set the date and time.
Outlook holds the email and sends at the scheduled time even if you're offline. Email lands when you wanted.
Search effectively
Outlook search is powerful if you use operators. Some useful ones:
- from:name – emails from a specific person
- to:name – emails sent to specific recipient
- subject:keyword – search in subject only
- hasattachment:yes – only emails with attachments
- received:thisweek – filters by date
Combine them – "from:john subject:invoice hasattachment:yes" finds emails from John with the word invoice in subject, with attachments. Way faster than scrolling.
Outlook on mobile
The mobile app on iOS and Android is solid. Same Focused Inbox, swipe gestures customizable to archive, delete, snooze, or flag emails.
Set up multiple accounts in the same app. Work and personal can both live in Outlook without switching apps. Settings > Add account.
