How to request someone's calendar in Outlook

To see someone else's calendar in Outlook, you send them a sharing request — a message asking permission to view their schedule. The person you're asking can accept, decline, or grant you limited access (like seeing only free/busy time instead of event details). Outlook handles this through the calendar sharing feature built into the application itself, not through a separate tool or email.

The exact steps depend on whether you're using Outlook on the web, Outlook desktop, or Outlook on a phone. The core idea is the same: you find the person's name, request access, and wait for them to respond. They'll see a notification asking whether to share their calendar with you.

Key Takeaways

  • Calendar sharing requests go through Outlook's built-in sharing feature, not through email or a separate system.
  • The person you're asking receives a notification and can choose what level of access to grant — full details, free/busy only, or no access.
  • Outlook on the web, Outlook desktop, and Outlook mobile all have slightly different steps, but all use the same sharing mechanism.
  • Once someone shares their calendar with you, it appears in your calendar list and updates in real time as they add or change events.

Requesting calendar access in Outlook on the web

Open Outlook on the web and go to the Calendar section. On the left side, you'll see your own calendars listed. Below that, look for a plus sign (+) or an Add calendar option. Click it and select Subscribe to a calendar or Add someone else's calendar — the exact wording varies by your Outlook version.

Type the person's email address in the box that appears. Outlook will send them a sharing request automatically. They'll see a notification in their Outlook inbox asking whether to share their calendar with you. Until they respond, you won't see their calendar in your list.

Once they accept, their calendar appears in your left sidebar under "Other calendars" or "Shared calendars." You can click their name to show or hide their events on your main calendar view.

Requesting calendar access in Outlook desktop

In Outlook desktop (Windows or Mac), click the Calendar tab at the bottom of the window. On the left side, you'll see your calendars listed. Right-click in the empty space below your calendars or look for a plus sign next to "Other calendars" or "Shared calendars."

Select Open Shared Calendar or Add Calendar (wording depends on your version). A dialog box opens asking for the person's email address. Enter it and click OK or Open. Outlook sends the sharing request to that person.

The person will receive a notification in their Outlook. Once they accept, their calendar appears in your sidebar. If they decline or don't respond, you won't see their calendar, and you may see an error message saying the calendar is unavailable.

Requesting calendar access on Outlook mobile

On Outlook for iPhone or Android, tap the Calendar tab at the bottom. Look for a plus sign (+) or a menu icon (three horizontal lines) at the top of the screen. Tap it and select Add calendar or Subscribe to calendar.

Enter the person's email address and tap Add or Send request. The request goes to them immediately. On mobile, you may see a slight delay before their calendar appears in your list after they accept, as the app syncs with the server.

What happens after you send a sharing request

The person you've asked receives a notification in their Outlook inbox. The notification says something like "[Your name] wants to view your calendar" and gives them options: Share, Share limited details, or Don't share.

If they choose Share, you see all their events, including titles, times, and descriptions. If they choose Share limited details, you see only whether they're busy or free at each time — not what they're doing. If they choose Don't share, you see nothing, and their calendar doesn't appear in your list.

Some organizations set up default sharing rules, so the person might not see a notification at all — their calendar might share automatically based on your company's policy. Check with your IT department if you're unsure whether requests are needed in your workplace.

Troubleshooting when a calendar request doesn't work

If you send a request and nothing happens, first check that you entered the correct email address. A typo is the most common reason a request fails silently. If the address is correct, the person may not have seen the notification yet — calendar sharing requests can take a few minutes to arrive.

If several hours pass and the person hasn't responded, they may have declined without telling you, or their Outlook settings may block sharing requests. Ask them directly whether they received the notification. They can also manually share their calendar with you by going to their calendar settings and adding your email address, which bypasses the request step entirely.

If you see an error message like "Calendar not found" or "Access denied," the person has either declined your request or removed your access. You'll need to send a new request, and they'll need to accept it again.

Sharing your own calendar with someone else

If someone asks to see your calendar, you don't have to wait for them to request it — you can share it proactively. In Outlook on the web, right-click your calendar name and select Sharing permissions or Share. In Outlook desktop, right-click your calendar and look for Properties or Sharing. Enter the person's email address and choose what level of access to give them.

You can share your calendar with multiple people at different permission levels. For example, you might give your manager full access to see all event details, but give colleagues only free/busy access so they can see when you're available without knowing what you're doing.

Frequently Asked Questions

Can I see someone's calendar if they don't accept my request?

No. Until they accept and choose a sharing level, their calendar won't appear in your list. If they decline, you'll need to ask them again or request access through a different method, like asking them to share their calendar directly from their settings instead of waiting for your request.

What's the difference between "Share" and "Share limited details"?

"Share" shows you everything — event titles, times, descriptions, and locations. "Share limited details" shows only whether they're busy or free at each time slot, without revealing what the events are. Use limited details if you just need to find a free time to meet.

How long does it take for a calendar to appear after someone accepts?

Usually a few seconds to a minute. On mobile, it may take a few minutes as the app syncs. If it doesn't appear after 10 minutes, try closing and reopening Outlook or refreshing the calendar view.

Can I request access to someone's calendar if they're outside my organization?

Yes, if they use Outlook or Microsoft 365. The process is the same — enter their email address and send the request. They'll receive it and can accept or decline. If they use a different email service, you may not be able to request access through Outlook's sharing feature.

What if I accidentally sent a sharing request to the wrong person?

You can't unsend a request, but you can ask the person to decline it, and you can send a new request to the correct person. The wrong recipient will just see a notification they can ignore or decline.
