How to Create a Shared Calendar in Outlook for a Team

If your team needs to add and edit events together, create a Microsoft 365 group calendar. Creating the group gives it a shared calendar, and group membership controls access. A blank Outlook calendar or shared mailbox calendar may fit better if you need individual sharing permissions or a shared email address.

How to Create a Shared Calendar in Outlook for a Team
How to Create a Shared Calendar in Outlook for a Team

If your team needs to add and edit events together, create a Microsoft 365 group calendar . Creating the group gives it a shared calendar, and group membership controls access. A blank Outlook calendar or shared mailbox calendar may fit better if you need individual sharing permissions or a shared email address. [2]

Quick checklist

  • Choose a group calendar, a new Outlook calendar, or a shared mailbox calendar.
  • Check whether a team group already exists.
  • Create the group and confirm its privacy setting.
  • Add the right members and another owner.
  • Save a test event on the group calendar.
  • Ask a teammate to confirm they can see it.
  • Add attendees when an email invitation is needed.

Before you start

You’ll need: A work or school account with a qualifying Microsoft 365 subscription, access to Outlook on the web, a team name, and your teammates’ email addresses. Your organization may restrict who can create groups. [1]

Time and cost: Plan roughly 10 minutes if you can create groups yourself; an IT approval can take longer. The group uses your organization’s Microsoft 365 subscription. Check with your admin if you need a subscription or a shared mailbox.

Privacy: Choose Private if calendar details should be limited to approved members. People across your organization can view a public group’s content. [1]

Which type of shared calendar should you create?

Choose When it fits Important trade-off
Microsoft 365 group calendar Team members should schedule and edit events together. Members can change group events. Use a private group when access should be limited. [2]
New, blank Outlook calendar You want a separate calendar under your account to share with selected people. You grant access to people individually; it is not a Microsoft 365 group calendar. [4]
Shared mailbox calendar The team also needs a shared email address and admin-managed access. An admin creates the mailbox and adds members. [6]

Already have a Microsoft 365 group for this team? Check its calendar before creating another. A calendar group in classic Outlook is different: it collects existing calendars in one view rather than creating a shared schedule. [8]

How to create a Microsoft 365 group calendar in Outlook

Use Outlook on the web for these steps. In new Outlook for Windows , you can also open Groups → New Group ; the web version is a fallback if your menus differ. [1]

How to create a Microsoft 365 group calendar in Outlook

  1. Sign in to Outlook on the web with the work or school account your team uses.
  2. Select Groups in the left app bar. If it is missing, ask IT whether Microsoft 365 Groups are available to your account.
  3. Select New Group → New Group. The group setup form should open.
  4. Enter a name and description, such as “Field Operations Schedule” and “Site visits and team coverage.” Enter a group email address if prompted.
  5. Set Privacy to Private unless everyone in your organization should be able to view the group’s content. Check the selection before continuing.
  6. Select Create. Confirm that the group appears in your Groups list.
  7. Add your teammates when prompted. Enter their names or email addresses, select Add , and check the member list for missing or unintended people.
  8. Assign another owner. Open the group, select its member count, and change a trusted teammate’s role from Member to Owner . Confirm that both owners appear in the list. [3]
  9. Open Calendar and select the group under Groups in the calendar list. Its calendar may be empty until you add an event.
  10. Add a test event with the group calendar selected, then ask a member to confirm they can see it. If members also need invitations in their inboxes, add the group as an attendee. Placing an event on the group calendar does not automatically invite every member. [2]

The calendar belongs to the Microsoft 365 group, not to one teammate’s additional calendar. Adding someone to the group gives them access to its shared resources, including the calendar.

Other ways to create a team calendar in Outlook

Create a new Outlook calendar without a group

In new Outlook, open Calendar → Home → Add Calendar → Create blank calendar . Name it, choose where to add it, and select Save . In classic Outlook, use Calendar → Folder → New Calendar . This creates a separate calendar under your account, not a group-owned calendar. [4]

To give teammates access to that new calendar , follow Microsoft’s calendar editing and permissions guide . Select the new calendar—not your primary one—when granting access. Editor access can be given on an additional calendar; delegate access is for the primary calendar. If you meant to share your existing personal calendar instead, use Microsoft’s personal-calendar sharing instructions .

Create a shared mailbox calendar

Ask an admin to open the Microsoft 365 admin center → Teams & groups → Shared mailboxes → Add a shared mailbox , enter a name and address, save, and select Add members to this mailbox . The mailbox comes with a calendar. After the admin adds members, they can reopen Outlook and select the shared mailbox in Calendar. [6]

Choose this route when the team also needs a shared email address or IT-managed access. Members with mailbox access can create and manage calendar appointments; adding them does not provide calendar-only, read-only access. [7]

Use an existing team group

Open Calendar → Groups and select the group your team already uses. Ask its owner to add missing teammates through the member list. The group already has a shared calendar, so you do not need to create another group. [2]

Troubleshooting

  • No Groups or New Group option? Sign in with your work or school account. If it is still missing, ask IT whether your subscription and organization settings allow group creation.
  • A teammate cannot find the calendar? Open the group’s member count, select Add members , and confirm their address is listed.
  • People outside the team can see the group? Ask a group owner or admin to check its privacy setting before adding sensitive event details.
  • An event appears on your own calendar? Check which calendar was selected in the event form, then create the team event with the group calendar selected.
  • Members see an event but received no invitation? Add the group to the attendee list or select Invite members when available.
  • Someone edits or cancels a group event? Group members can manage its events. For a meeting only you should control, create it on your own calendar and invite the group.
  • A shared mailbox calendar is missing? Ask the admin to confirm your membership, then close and reopen Outlook. In new Outlook, check Calendar for the shared mailbox.
  • Events on an additional calendar do not block your availability? Outlook’s Scheduling Assistant uses your primary calendar for availability. Put appointments that must mark you busy on your primary calendar. [4]

Menus vary between Outlook on the web, new Outlook for Windows, and classic Outlook. Your organization may also limit group creation. If a label is missing, check your version and account permissions before creating a different type of calendar.

Frequently asked questions

How do I create a new calendar in Outlook?

In new Outlook, open Calendar, select Add Calendar, then Create blank calendar. Name it and save it. This creates an additional calendar under your account, not a Microsoft 365 group calendar.

What is the best Outlook shared calendar for a team?

Use a Microsoft 365 group calendar when members should schedule and edit together. Use a shared mailbox calendar if the team also needs a shared email address and admin-managed membership.

Is an Outlook calendar group the same as a Microsoft 365 group calendar?

Can I add team members after creating the group?

Yes. Open the group, select its member count, and choose Add members.

Will a group-calendar event invite every member?

No. Add the group as an attendee if members need an invitation, rather than only placing the event on the shared calendar.

Why can’t I see New Group in Outlook?

Check that you’re signed in with your work or school account. If the option is still missing, ask IT whether your subscription and organization settings allow group creation.

Want a desktop email client?
