How to Send a Calendar Invite in 2026 (Google, Outlook, Apple)

I’m Nir Sabato, co-founder of Catch, the AI Executive Assistant built to take admin work off executives’ plates. Most of my week is spent talking to leaders at US mid-market companies, and I keep noticing the same thing: a lot of them lose real time on tiny tasks. Sending a calendar invite is a classic one. It sounds like nothing, but picking a time, adding the right people, and then making sure the invite actually lands all stacks up over a busy week.

So this guide walks through how to send a calendar invite in the three tools most professionals live in: Google Calendar, Outlook, and Apple Calendar, on both desktop and mobile. I’ll keep it practical. The exact steps, the settings that actually matter, and why invites sometimes just vanish. And at the end, I’ll show you how to skip the whole thing.

How to send a calendar invite (the short version)

To send a calendar invite, you create an event, add the people you want to invite as guests, and save it. Your calendar app then emails each guest an invitation they can accept or decline. The buttons look a little different between Google, Outlook, and Apple, but the three steps never change: create the event, add guests, send.

That’s really all there is to the idea. The rest of this guide is the platform-specific stuff, plus the bits that trip people up: guest permissions, recurring meetings, and invites that quietly fail to show up.

How to send a Google Calendar invite

To send a Google Calendar invite, create an event, add guests by email, and save it. Google handles the rest, firing off an email invitation to each guest automatically. Here’s how it plays out on desktop and mobile.

On desktop (Google Calendar web)

1. Go to calendar.google.com and sign in.
2. Click Create in the top-left, or click directly on the day and time you want.
3. Give the event a clear title, then set the date, start time, and end time.
4. Click Add guests on the right and type each person’s email address. Google will autocomplete from your contacts.
5. (Optional) Add a location, a video conferencing link with Add Google Meet video conferencing, and a description or agenda.
6. Click Save. When Google asks if you want to send invitation emails, choose Send.

Each guest receives an email invite and the event appears on their calendar with Yes / No / Maybe buttons. For more detail, including guest permissions and fixes, see our full guide on how to send a Google Calendar invite.

On mobile (Google Calendar app)

1. Open the Google Calendar app and tap the + button in the bottom-right.
2. Tap Event.
3. Add a title, then set the date and time.
4. Tap Add people and enter the guests’ email addresses.
5. Tap Save in the top-right. Invitations send automatically.

Guest permissions worth setting

Before you hit save, glance at the three guest permission checkboxes: modify event, invite others, and see guest list. For most meetings, leave “invite others” and “see guest list” on so people can coordinate among themselves. For sensitive or one-on-one meetings, switch off “see guest list” so attendees can’t tell who else got invited.

How to send a calendar invite in Outlook

To send a calendar invite in Outlook, create a new event or meeting, add attendees in the Required or Optional field, and click Send. Outlook then drops the invite into each person’s inbox and calendar. The steps shift a little depending on whether you’re in the new Outlook, the classic desktop app, or mobile. For a deeper walkthrough, see our dedicated guide on how to send a calendar invite in Outlook.

In the new Outlook and Outlook on the web

1. Open Outlook and go to the Calendar from the left sidebar.
2. Click New event in the top-left.
3. Add a title, then set the date, start time, and end time.
4. In the Invite attendees field, type each person’s email address. Use the Optional option to mark attendees whose presence isn’t required.
5. (Optional) Add a Teams meeting link with the Teams meeting toggle, plus a location and an agenda in the body.
6. Click Send. The invite goes out and lands on each attendee’s calendar.

In classic Outlook for Windows

1. Open Outlook and switch to the Calendar view at the bottom-left.
2. On the Home tab, click New Meeting (not “New Appointment” - an appointment has no attendees).
3. In the To field, add the email addresses of everyone you want to invite.
4. Set the subject, location, date, and time. Use Scheduling Assistant at the top to see when attendees are free.
5. Click Send.

On the Outlook mobile app

1. Open the Outlook app and tap the Calendar icon at the bottom.
2. Tap the + button to create a new event.
3. Add a title, then tap People to add attendees by email.
4. Set the date, time, and any location or online meeting link.
5. Tap the checkmark or Save in the top-right to send.

A note on the Scheduling Assistant

The Scheduling Assistant is far and away the biggest time-saver in Outlook. It overlays everyone’s free/busy times so you can grab a slot that actually works, no back-and-forth emailing required. Inviting more than two people? Use it. It’s the difference between sending one invite and sending five reschedules.

How to send an Apple Calendar invite

To send an Apple Calendar invite, create an event, add people in the Invitees field, and the invitation goes out the moment you save. Recipients get it by email, or as a calendar notification if they’re on Apple devices. Apple Calendar runs the same way across Mac, iPhone, and iPad.

On a Mac

1. Open the Calendar app.
2. Double-click a day, or click the + button, to create a new event.
3. Type the event name, then set the date, start, and end times.
4. Click Add Invitees and enter each person’s email address.
5. Add a location or notes if you need to, then click Send.

On an iPhone or iPad

1. Open the Calendar app and tap the + in the top-right corner.
2. Add a title, then set the start and end times.
3. Tap Invitees, enter the email addresses of the people you’re inviting, and tap Done.
4. Tap Add in the top-right. The invitations send automatically.

One thing to know about Apple invites

Apple Calendar sends invites cleanly to other Apple users and to anyone on iCloud. Inviting people on Google or Outlook? The invite still arrives by email. Just make sure the event lives on your iCloud calendar and not your phone’s local “On My iPhone” calendar, which can’t send invitations at all. That’s the single most common reason an Apple Calendar invite never reaches anyone.

What to do when a calendar invite doesn’t arrive

When a calendar invite doesn’t arrive, it’s usually one of three things: a mistyped email address, the invite landing in spam, or the event sitting on a calendar that can’t send invitations in the first place. Run through these before you resend.

• Double-check the email address. One typo and the invite disappears into the void, no error message, nothing. Confirm the address character by character.
• Ask the recipient to check spam. Invitations from an unfamiliar sender get filtered all the time. Have them search their inbox for the event title.
• Confirm the event is on a sending calendar. In Apple Calendar that means iCloud, not a local calendar. In Google and Outlook it means your main account, not a read-only shared calendar.
• Verify you actually chose “Send.” Google Calendar is the worst offender here. It’s easy to save an event and breeze right past the “send invitation emails” prompt, and then nobody gets notified.
• Resend the invitation. Open the event, remove the guest, save, then re-add them and save again. That forces a fresh invite out the door.

Nearly every “the invite never showed up” headache traces back to one of these five. None are hard to fix. They’re just easy to miss when you’re moving fast.

How to send better calendar invites every time

Sending the invite is the easy part. Sending a good one, the kind that doesn’t spark three follow-up questions, is really just a handful of habits.

• Write a specific title. “Q3 budget review, Mark + finance” tells people a lot more than “Meeting.”
• Always include an agenda or purpose. Even one line in the description sets expectations and tends to make the meeting shorter.
• Add the video link before you send. Nobody should be scrambling for the Zoom, Meet, or Teams link two minutes before the call.
• Respect time zones. Inviting people in other regions? Double-check the time zone on the event so no one shows up an hour off.
• Set the right guest permissions. Decide up front whether attendees should see each other or invite others, especially for anything sensitive.

Each of these takes seconds, and together they’re the difference between an invite people trust and one they ignore.

Let an AI assistant handle the invites for you

Here’s the real point of everything above: you shouldn’t be the one doing it. Knowing how to send a calendar invite in Google, Outlook, and Apple is handy. But spending your week creating events, hunting for free slots, and resending invites that didn’t land is not the work you’re there to do.

Which is exactly why we built Catch. It’s an AI Executive Assistant that handles scheduling end-to-end. You tell it what you want, by text message, email, Slack, iMessage, or voice, and it runs with it. Something as loose as “set up 30 minutes with Mark next week, mornings only” is plenty. Catch checks your calendar, coordinates with the other person, lands on a time that works, sends the invite, and keeps the guest list straight. You never open a calendar app.

And it lives in the same tools you already use. Catch connects to your Gmail or Outlook in under three minutes, then reads and writes to your Google Calendar or Outlook Calendar the way any calendar integration would. From there it’ll create new meetings, generate scheduling links with your exact constraints, book times from scheduling links other people send you, and tweak existing invites: adding or removing participants, shortening or stretching a meeting, accepting or declining on your behalf.

It’s also proactive, which is the part people don’t expect. When two meetings start to collide, Catch doesn’t just flag the conflict and leave it for you. It reaches out to reschedule and actually resolves it. When it has enough context, it acts. When something’s genuinely murky, like which “John” you meant, it can ask a quick question or reasonably infer the answer from what it already knows about you, rather than rigidly stopping every time. It weighs the situation the way a human assistant would before doing anything on your behalf.

For executives at mid-market companies, that’s the real shift: going from knowing how to send a calendar invite to never having to think about it again. It’s the same leap you get from any good AI scheduling assistant that runs your calendar end-to-end. Catch is a flat $99/month, with a 10-day free trial and no per-action fees. If your calendar is eating hours you’d rather spend leading, that’s a trade worth making.
