How to Set Multiple Reminders for an Outlook Calendar Event (2026)
A common Outlook question: “Can I get notified at 45, 30, and 10 minutes before a meeting?” By default, no. Outlook allows exactly one reminder per calendar event — in classic Outlook, new Outlook, and on the web. Pick 15 minutes and that’s your only built-in alert.
If one reminder isn’t enough — for travel, prep, or just because a single nudge is easy to dismiss and forget — here are four ways to layer on more.
1. Set the Built-In Reminder First
Start with the native one, then add to it.
- Open the event.
- Use the Reminder dropdown.
- Choose your lead time (e.g., 15 minutes).
- Save.
Every method below stacks on top of this single reminder.
2. Change the Default Reminder for All Events
This won’t give you multiple reminders, but it makes sure your baseline is always set so you’re not relying on memory.
Classic Outlook for Windows
File → Options → Calendar → set Default reminders.
New Outlook and Outlook on the web
Settings → Calendar → Events and invitations → set the default reminder.
3. Create a Second Event as an Earlier Reminder
The simplest no-tools trick: because each event carries its own reminder, two events = two reminders.
- Create a short event earlier in the day, or the day before.
- Title it
Prep: [meeting name]. - Set Show As → Free so it doesn’t block your time.
- Give it its own reminder (say, 1 day or 2 hours before).
You now get a day-before heads-up and the 15-minute warning on the real meeting. Add a third placeholder for a third nudge. It’s manual, but it works in every version with no setup.
4. Stagger Reminders with Power Automate
For true multiple reminders on a single event — no duplicates — use Power Automate (included with most Microsoft 365 business plans).
- Create a new flow.
- Trigger: When an event is added or modified (Office 365 Outlook).
- Add a Delay until action set to 45 minutes before the start.
- Add a Send me an email / mobile notification action.
- Repeat the delay + notify pair for 30 minutes and 10 minutes before.
This fires a notification at each interval you defined, all tied to one calendar event. It takes a few minutes to build but then applies to every matching meeting.
5. Automate Multi-Stage Reminders Without Building a Flow
Power Automate is powerful but fiddly — you’re maintaining a flow, mapping fields, and debugging delays. If you’d rather just say what you want, an assistant can handle it.
Carly connects to Outlook and 200+ other apps and can watch an event, then nudge you at several intervals — and across channels like email or chat, not just a desktop pop-up that’s easy to miss. Tell it “remind me 1 day, 1 hour, and 10 minutes before client calls” and it manages the rest. Carly starts at $35/month.
Quick Reference
| Method | True multi-reminder? | Setup |
|---|---|---|
| Built-in reminder | No (one only) | None |
| Default reminder | No | One-time setting |
| Second event | Yes (one per event) | Manual, per meeting |
| Power Automate | Yes | One flow, reusable |
| AI assistant | Yes, multi-channel | Just ask |
Outlook’s one-reminder limit is a real constraint, but a Power Automate flow (or an assistant that builds one for you) gets you the staggered 45/30/10 notifications most people actually want.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
