Outlook Calendar Permissions Explained

Outlook calendar permissions control exactly how much of your schedule another person can see and whether they can change it. There are five levels: Can view when I'm busy, Can view titles and locations, Can view all details, Can edit, and Delegate - ranging from showing only free/busy blocks up to letting someone manage meetings on your behalf. This guide explains what each level reveals, how to set and remove them, how to view a colleague's calendar, and how to export your own.

The steps below were checked against Microsoft's current support documentation in June 2026 and cover new Outlook for Windows, Outlook on the web, and classic Outlook where they differ.

Outlook calendar permission levels explained

When you share a calendar, Outlook asks which level of access to grant. Each higher level includes everything the levels below it show, plus more. Here's what each one actually exposes:

• Can view when I'm busy - The person sees only blocks of time marked Free, Busy, Tentative, or Away. No subjects, no locations, no details. This is the right level for scheduling meetings without revealing what you're doing.
• Can view titles and locations - Adds the event's subject line and location to the free/busy view. Good for teammates who need to know roughly what a block is for.
• Can view all details - Reveals the full event: subject, location, attendees, and the description/notes. Use this only with people you trust with the contents of your calendar.
• Can edit - Everything in view all details, plus the ability to create, move, and delete events on your calendar. This is genuine write access.
• Delegate - The same power as an editor, but the delegate also receives meeting requests and responses sent to you and can respond on your behalf. Delegates can only be assigned to your primary calendar.

Two important limits: you can't grant Can edit or Delegate to people outside your organization, and delegate-level access is reserved for your primary calendar, not secondary ones. For private events, a delegate sees them only if you check Let delegate view private events when assigning the role.

How to set Outlook calendar permissions

Setting permissions starts from the calendar you want to share. The flow is nearly identical in new Outlook and on the web.

New Outlook for Windows and Outlook on the web

1. Go to Calendar in the left sidebar.
2. On the Home tab, click Share Calendar (on the web, hover the calendar name, click the ... menu, and choose Sharing and permissions).
3. Type the person's name or email address.
4. Use the dropdown next to their name to choose a permission level - Can view when I'm busy, Can view titles and locations, Can view all details, Can edit, or Delegate.
5. For a delegate, optionally check Let delegate view private events and choose how meeting invites are routed.
6. Click Share.

Classic Outlook for Windows

1. Open Calendar and select the calendar.
2. On the Home tab, click Calendar Permissions (or Share Calendar).
3. Click Add, choose the person, then pick a Permission Level from the list.
4. Click OK.

If your goal is simply to send an invite for a single meeting rather than grant standing access, that's a different task - see how to send a calendar invite in Outlook.

How to change or remove calendar permissions

Permissions aren't permanent. You can dial someone up to an editor or strip access entirely at any time.

1. Open Calendar and go back to Share Calendar / Sharing and permissions for that calendar.
2. Find the person in the list of people who already have access.
3. To change their level, click the dropdown next to their name and pick a new level.
4. To remove access, click Remove (the trash or X icon) next to their name.

Changes take effect quickly but not always instantly - if the other person already added your calendar, it may take a sync cycle for their view to reflect the new level. If access seems wrong after a change, give it time before assuming something broke; our notes on Outlook calendar not syncing cover the usual delays.

Or skip the permissions dance for one-off events: highlight the event text anywhere in your browser, right-click, and the Text to Outlook Calendar extension creates the event for you - dates, times, and locations filled in automatically. When you just need to get an event onto your own calendar fast, that's quicker than configuring sharing for anyone.

How to view someone's calendar in Outlook

Viewing a colleague's calendar requires that they (or an admin) have granted you at least Can view when I'm busy. Once that's in place, there are two ways to open it.

Accept a sharing invitation

The simplest path: when someone shares their calendar with you, you receive an email. Open it and click Accept. The calendar appears under People's calendars (or Shared calendars) and respects whatever permission level they granted.

Add the calendar from the directory

If no invitation arrived but you have permission, add it yourself:

1. In Calendar, click Add calendar in the left pane.
2. Choose Add from directory (classic Outlook: Open Shared Calendar).
3. Select your account, then type the person's name or email address.
4. Pick them from the results and click Add.

The person's calendar opens beside yours. How much you see depends entirely on the level they assigned: with Can view when I'm busy you'll get colored blocks only; with Can view all details you'll see subjects, locations, and notes. If you're seeing less than you expected, ask them to raise your permission using the steps in the section above. To request access cleanly, you can also have them follow how to share their Outlook calendar.

For team-wide visibility rather than one-to-one sharing, a shared calendar in Outlook is usually the better structure.

How to export Outlook calendar

Exporting writes your calendar - or a date range of it - to an .ics file you can back up, move to another account, or hand to someone outside Outlook. The method depends heavily on your version.

Classic Outlook for Windows (full export to .ics)

Classic Outlook has the most complete export:

1. Open Calendar and select the calendar to export.
2. Click File > Save Calendar.
3. In the dialog, set Save as type to iCalendar Format (.ics).
4. Click More Options to choose a date range (for example, Whole calendar) and the level of detail (Availability only, Limited details, or Full details).
5. Click OK, then Save.

New Outlook and Outlook on the web (publish to get an ICS link)

New Outlook and the web don't offer a one-click file download of your whole calendar. Instead you publish it and copy a link:

1. Open Settings (gear) > Calendar > Shared calendars (in new Outlook, this is under View > Calendar settings).
2. Under Publish a calendar, choose the calendar and the permission - typically Can view all details.
3. Click Publish.
4. Copy the ICS link (or the HTML link).

That ICS link is a read-only, subscribable URL. Anyone you give it to can subscribe to it in their own calendar app, and it stays in sync. If you instead need a static file, open the ICS link in a browser to download a snapshot, or use classic Outlook's Save Calendar route above.

A few realities to keep in mind when exporting: the classic desktop method exports one calendar at a time, and the published ICS link is read-only - editing the file or link won't change your live calendar. If you only need a single event or a small batch as a clean .ics, it's often faster to build one with a free ICS file generator than to publish your entire calendar.

For moving events into Outlook rather than out, see how to add a calendar to Outlook, which covers subscribing to ICS URLs and importing files.

Quick reference: which permission level to choose

Grant Can view when I'm busy when someone only needs to find open slots to book you. Step up to Can view titles and locations for teammates who coordinate closely. Reserve Can view all details for trusted colleagues who need the full context of your events. Use Can edit for an assistant or partner who manages your calendar, and Delegate when that person should also field meeting invites on your behalf.

And whenever the real task is just getting an event onto a calendar from some text you're looking at, you don't need to touch permissions at all. Highlight the text, right-click, and the Text to Outlook Calendar extension parses the date, time, and location and creates the event in one click. It's rated 4 stars and free for your first five events - grab it from the Outlook extension page.

Frequently Asked Questions

What are the Outlook calendar permission levels?

There are five: Can view when I'm busy (free/busy blocks only), Can view titles and locations, Can view all details (subject, location, attendees, and notes), Can edit (create, move, and delete events), and Delegate (editor rights plus receiving and responding to meeting invites on your behalf). Each level includes everything the levels below it show.

How do I view someone's calendar in Outlook?

First, they need to grant you at least Can view when I'm busy. Then either accept the sharing invitation they emailed you by clicking Accept, or add it yourself: in Calendar, click Add calendar > Add from directory (Open Shared Calendar in classic Outlook), search their name or email, and click Add. How much detail you see depends on the permission level they assigned.

How do I export my Outlook calendar to an .ics file?

In classic Outlook, open Calendar, click File > Save Calendar, set the type to iCalendar Format (.ics), use More Options to pick a date range and detail level, then Save. In new Outlook and on the web, you publish the calendar instead: go to Calendar settings > Shared calendars, choose the calendar and Can view all details, click Publish, and copy the ICS link.

Can I give someone outside my company edit access to my Outlook calendar?

No. Can edit and Delegate permissions can only be granted to people inside your organization. External users can be given view-only access - at most Can view all details - typically through a published ICS link rather than a direct edit grant.

How do I remove someone's access to my Outlook calendar?

Open Calendar, go to Share Calendar or Sharing and permissions for that calendar, find the person in the list of people with access, and click Remove (the trash or X icon) next to their name. The change applies on the next sync cycle, so it may take a short while before their view updates.
