How to Send a Calendar Invite in Outlook: The 2026 Step-by-Step Guide

I’m Nir Sabato, co-founder of Catch. A good chunk of my week is spent watching how executives and their assistants actually use their calendars, and the same thing keeps surfacing. Sending a calendar invite in Outlook should take ten seconds. In practice it turns into a small chore. You open the wrong Outlook. The “New Meeting” button has wandered off somewhere. Someone gets left off the invite, or the Teams link just doesn’t attach.

So here’s a walkthrough of how to send a calendar invite in Outlook the right way, across every version you’re likely to be on in 2026: the new desktop app, classic desktop Outlook, Outlook on the web, and the mobile app. By the end you should be able to build a clean invite, add the right people, attach a meeting link, and avoid the handful of mistakes that make invites bounce around or quietly never show up.

What a calendar invite in Outlook actually is

A calendar invite in Outlook is a meeting event you create on your own calendar and then send to other people as attendees. It lands on their calendar with a time, a location or link, and an RSVP attached. The moment you add even one other person, Outlook stops treating the event as a private appointment and starts treating it as a meeting invite. Everyone on the list gets an email they can accept, decline, or mark tentative.

That difference is worth pinning down. An appointment is just a block on your own calendar. A meeting invite is that same block with attendees attached, and it’s what most people actually mean when they ask how to send a calendar invite in Outlook. Everything below creates real invites, not personal time blocks.

How to send a calendar invite in the new Outlook (desktop)

The new Outlook for Windows and Mac is the default at most US mid-market companies now, so odds are this is the version you’re sitting in. Here’s how to send a calendar invite on Outlook’s newest desktop app.

1. Open Outlook and click the calendar icon in the left navigation bar.
2. Click New event in the top-left corner (or just double-click the day and time you want).
3. Type a clear title - name the meeting for what it’s about, like “Q3 budget review,” not “Meeting.”
4. In the Invite attendees field, start typing names or email addresses. Outlook autocompletes from your contacts and company directory.
5. Set the start and end time, and toggle All day only if it genuinely runs all day.
6. Add a location for in-person meetings, or toggle on Teams meeting to attach a video link automatically.
7. Write a short note in the body so people know why they’re invited and what to prepare.
8. Click Send.

Hit Send and the invite emails out to every attendee while the event shows up on your calendar right away. People can respond, and their answers roll up in one place so you can see who’s coming without chasing anyone.

Optional and required attendees

You can mark each person you add as required or optional. Click their name after adding them, or use the Optional field if your version offers one. Small thing, but it tells people whether they genuinely need to be in the room, and meetings tend to stay leaner when you bother to do it.

How to send a calendar invite in classic Outlook (desktop)

Plenty of companies still run classic Outlook for Windows. The layout looks a bit different, but the idea hasn’t changed.

1. Click the calendar icon at the bottom-left of the Outlook window.
2. On the Home tab, click New Meeting (not “New Appointment” - that one has no attendees).
3. Add people in the To field, or click To to pick them from your address book.
4. Fill in the Subject and Location.
5. Set the Start time and End time.
6. Click Teams Meeting in the ribbon if you want a video link.
7. Use Scheduling Assistant in the ribbon to see when everyone is free before you lock the time.
8. Click Send.

The Scheduling Assistant is the part people overlook. It lines up each attendee’s free/busy bars side by side, so you can pick a slot that actually works instead of guessing and then rescheduling twice.

How to send a calendar invite in Outlook on the web

If you live in Outlook through a browser, whether that’s Outlook.com or Microsoft 365 webmail, the steps are nearly the same as the new desktop app.

1. Go to your Outlook calendar and click the calendar icon on the left.
2. Click New event at the top.
3. Add a title, then type names in the Invite attendees box.
4. Choose the date and time, and pick Repeat if it’s a recurring meeting.
5. Toggle Teams meeting on for a video link, or type a physical location.
6. Add a quick agenda in the description.
7. Click Send.

The web version comes in handy on a shared machine or a personal laptop where you’d rather not open the full desktop app. It all syncs back to the same calendar anyway.

How to send a calendar invite from the Outlook mobile app

Sending an invite from your phone earns its keep when you’re walking out of one meeting and want to lock in the next before it slips your mind.

1. Open the Outlook app and tap the calendar icon at the bottom.
2. Tap the + button to create a new event.
3. Enter a title, then tap People to add attendees by name or email.
4. Set the date, start time, and end time.
5. Tap Location for a place, or turn on Teams meeting for a link.
6. Tap the checkmark or Send in the top corner.

The mobile flow is deliberately bare-bones, but it still produces a real invite that lands on everyone’s calendar.

How to add a Teams or video link to your invite

For a Microsoft Teams link, flip on Teams meeting while you’re building the event. Outlook generates the join link and dial-in details and drops them straight into the invite. Nothing to schedule separately over in Teams.

Running Zoom or Google Meet instead? Install that tool’s Outlook add-in, then click its button in the event window to drop in the link. Once the add-in is set up, it behaves more or less like the Teams toggle does.

How to forward or resend a calendar invite

Already sent the invite and now you need to add someone? Two clean ways to do it.

• Add an attendee: Open the event from your calendar, drop the new person into the attendees field, and click Send Update. You can choose to notify only that one person so you don’t re-ping the whole group.
• Forward the invite: Open the event and click Forward. This sends it along as an email the recipient can accept, which is handy when you want to loop someone in without formally changing the meeting.

One caution worth flagging: forwarding works fine, but it can quietly leave the organizer in the dark about who’s actually attending. When that matters, add people directly and send an update instead.

Common Outlook calendar invite problems (and fixes)

A handful of issues show up over and over. Here’s how to deal with each.

• Attendees say they never got the invite. Double-check that you clicked Send, not Save. Saving keeps the event on your own calendar without telling a soul.
• The invite went out but nobody can RSVP. Usually this means you made an appointment, not a meeting. Reopen it, add attendees, send an update.
• The “New Meeting” button is nowhere to be found. You’re likely sitting in the mail view rather than the calendar. Switch over to the calendar first.
• Times look off for remote attendees. Confirm the time zone on the event, and switch on the second time zone display if your team is scattered across the country.
• A recurring meeting only updated one instance. When you edit, pick This and following events or All events instead of the single occurrence.

Most invite headaches come back to one of these. Get them right and your calendar stays clean.

Best practices for calendar invites that people actually accept

Sending the invite is the easy part. The fast, clean response is where a little discipline pays off. A few habits I’d push on any executive or admin:

• Name the meeting clearly. The title should tell people what it’s about before they ever open it.
• Add an agenda in the body. Even two lines on the purpose and the decision you need tends to lift your acceptance rate.
• Check availability first. Lean on Scheduling Assistant so you’re not playing reschedule tag. For a deeper look at picking the right times, our guide to smart scheduling goes further.
• Mark optional attendees as optional. Respect people’s time and they’ll respect your invites back.
• Send a short, well-written note. The same rules that make a good email apply here. See how to write a professional email for the format.

These are the instincts a great executive assistant brings to your calendar. Doing them by hand, for every meeting, every single day, eats up real time.

Let Catch handle the invites for you

Knowing how to send a calendar invite in Outlook is worth knowing. But actually building each one, every time, checking everyone’s availability, adding the right attendees, attaching the link, writing the note, then chasing the people who haven’t replied, is exactly the kind of admin you didn’t take a leadership job to do.

That’s the work Catch lifts off your plate. Catch is an AI Executive Assistant that lives in the channels you already use, Slack, email, text message, iMessage, and phone, and runs scheduling end to end. Tell it “set up a 30-minute review with Mark and Sarah next week, mornings only,” and it checks your calendar, coordinates the time, sends the Outlook invite, and manages the attendee list, all without you opening the calendar yourself. It connects to your Outlook calendar and email directly, so the invites go out exactly as if you’d built them by hand.

It also stays on top of the things that slip. When a conflict forms on your calendar, Catch flags it for your attention and reaches out to reschedule. When someone hasn’t responded to an invite that matters, it nudges them. To see how this fits a wider workflow, our piece on the AI executive assistant lays out the full picture, and our AI scheduling assistant guide digs into the scheduling side specifically.

At a flat $99 a month, that’s a lot of calendar admin you simply stop doing. You decide what the meeting is for. Catch sends the invite.
