How to ask for Outlook calendar access
To see someone else's Outlook calendar, you need them to share it with you first — you cannot request it directly through Outlook itself. The person who owns the calendar must open their settings and add your email address to their sharing list. Once they do, you will receive a notification, and the calendar will appear in your calendar list on the left side of Outlook.
The process takes less than a minute on their end, but it does require them to take action. You cannot force the share or work around it; Outlook's permissions are strict about who can see what. If someone declines to share, you have no technical workaround — you will need to find another way to coordinate, like asking them to send you their availability by email or text.
Key Takeaways
- The calendar owner must initiate sharing; you cannot request it through Outlook, only ask the person directly.
- Once shared, the calendar appears automatically in your Outlook sidebar under "Other calendars" and you can see their free and busy times.
- The owner can set different permission levels — some people share only their availability (free/busy), others show full event details.
- If you share a calendar with someone and they do not see it, ask them to check their junk email for the sharing notification.
What the calendar owner needs to do to share with you
The person whose calendar you want to see should open Outlook on their computer or phone and find their own calendar in the left sidebar. They right-click on the calendar name and select "Sharing and permissions" (on a Mac, this may say "Share calendar"). Then they type your full email address into the field that appears and choose what level of detail you can see.
They have three choices: "Can view when I'm busy", which shows only your free and busy blocks without event titles; "Can view titles and details", which shows everything; or "Can edit", which lets you add events to their calendar. Most workplaces use "Can view when I'm busy" for colleagues and "Can view titles and details" for direct reports or team members who need to know what someone is working on.
After they click "Share", Outlook sends you an email notification. You do not have to do anything — the calendar will show up in your Outlook automatically within a few minutes. If it does not appear, ask them to resend the invitation or check that they typed your email address correctly.
Where the shared calendar appears in your Outlook
Once someone shares their calendar with you, it lands in a section called "Other calendars" in your left sidebar, below your own calendar. You can click the eye icon next to it to hide or show it, and you can right-click on it to change the color so it stands out from your own schedule. The shared calendar stays in your Outlook until you remove it, even if the person stops sharing it with you later.
On Outlook's web version (outlook.com or Outlook on the web), shared calendars appear in the same "Other calendars" section on the left. You can overlay it on top of your own calendar to see both schedules at once, which is useful for finding meeting times. On Outlook mobile apps, shared calendars show up in the calendar list, though the interface is slightly different depending on whether you use iPhone or Android.
What happens if the person changes their mind about sharing
If someone shared their calendar with you and then removes the sharing, the calendar disappears from your Outlook within a few hours. You will not get a notification that they stopped sharing — you will just notice the calendar is gone. If you think this happened by accident, ask them directly; there is no way to see who has removed you from their sharing list.
The calendar owner can also change your permission level without removing you entirely. If they switch you from "Can view titles and details" to "Can view when I'm busy", you will still see their calendar, but event titles will disappear. Again, you will not get a warning — you will just notice the details are no longer visible.
Sharing your own calendar with others
If you want to share your calendar with a colleague, manager, or team member, follow the same steps the calendar owner used: right-click your calendar name, select "Sharing and permissions", type their email address, and choose a permission level. You can share with multiple people at once by adding them one at a time, or by typing several email addresses separated by semicolons (depending on your version of Outlook).
Think carefully about what permission level you give. "Can view when I'm busy" is safer if you work with people outside your team or organization, because it shows your availability without revealing what you are actually doing. "Can view titles and details" is more useful for people you work closely with, because they can see what meetings you are in and plan around them. "Can edit" should be rare — use it only for an assistant or someone who regularly schedules on your behalf.
Troubleshooting: Calendar does not appear after sharing
If someone shared their calendar with you but it is not showing up in your Outlook, first check your email junk or spam folder for the sharing notification. Outlook sends an email when someone shares a calendar with you, and sometimes email filters catch it by mistake. If you find it in junk, mark it as "not junk" and the calendar should appear in Outlook within a few minutes.
If the notification is not in your junk folder, ask the person who shared it to double-check that they typed your email address correctly. A single typo will send the invitation to the wrong address. They can also try removing you and re-adding you from scratch. On rare occasions, Outlook needs you to sign out and sign back in before a newly shared calendar appears — try that if nothing else works.
If you are using Outlook on the web (outlook.com) and a shared calendar still will not show up, try opening Outlook on your computer instead. Sometimes the web version lags behind the desktop app. Similarly, mobile apps can take longer to sync shared calendars than the desktop version does.
Frequently Asked Questions
Can I see someone's Outlook calendar without them sharing it with me?
No. Outlook does not allow you to view anyone's calendar unless they have explicitly shared it with you. There is no way to request access through Outlook itself — you have to ask the person directly, and they have to agree and set it up on their end.
What if my boss or coworker will not share their calendar with me?
You cannot force them to share. If you need to know their availability for scheduling purposes, ask them to send you their free times by email, or suggest a shared scheduling tool like When2Meet or a shared Google Calendar instead. Some organizations use calendar-sharing as a default practice, so if your workplace does not, that may be a conversation to have with your manager about team norms.
Can I see someone's calendar if they share it with my team email address instead of my personal email?
Only if your personal email is set up as an alias or forwarding address for that team email. If they shared it with a separate team mailbox that you do not have direct access to, you will not see it in your personal Outlook. Ask them to share it with your individual email address instead.
If I share my calendar, can people see my personal events or just work events?
That depends on the permission level you choose. If you set it to "Can view when I'm busy", they see only your free and busy blocks — no event titles at all, so personal events are hidden. If you set it to "Can view titles and details", they see the titles of all events, including personal ones, unless you mark those events as "private" before sharing. Mark an event private by opening it, clicking "Show as", and selecting "Private".
Do I need to accept a shared calendar invitation, or does it appear automatically?
It appears automatically. You will receive an email notification, but you do not need to click anything or confirm. The calendar will show up in your Outlook within a few minutes of the person sharing it. You can ignore the email notification if you want — the calendar is already in your account.
