Problem
The calendar is missing from Microsoft Teams, meetings do not appear, or Teams does not sync correctly with Outlook. You may see your meetings in Outlook but not in Teams, or Teams may show an empty calendar even though your account has scheduled meetings.
This is usually caused by account mismatch, Exchange Online mailbox issues, Teams app cache problems, Outlook calendar sync delays, missing licences, or organisation policies that disable the Teams calendar app.
Solution
Confirm you are signed in with the correct account, check whether your calendar works in Outlook and Outlook on the web, compare Teams desktop with Teams on the web, then ask your IT administrator to check licensing and Exchange settings if the calendar is still missing.
Step by step instructions
Confirm you are using the correct Microsoft account
Start by checking which account is signed in to Teams.
Open Microsoft Teams.
Select your profile picture or initials.
Confirm the email address shown.
If you use multiple Microsoft accounts, make sure Teams is signed in with the same work, school, or personal account that contains your Outlook calendar.
If the wrong account is signed in, sign out and sign back in with the correct one.
Check whether the calendar icon is hidden
The Teams calendar app may be hidden from the left side menu.
Look at the left navigation bar in Teams.
Select More apps or the three dots if available.
Look for Calendar.
If Calendar appears there, open it and pin it to the left menu if the option is available.
Check Outlook calendar
Open Outlook and confirm whether your meetings appear there.
You can also check Outlook on the web at:
Sign in with the same account used in Teams.
If the calendar is missing or empty in Outlook as well, the issue is not just Teams. It may be related to your mailbox, account, or calendar data.
Check Teams on the web
Open your browser and go to:
Sign in with the same account.
Check whether Calendar appears in Teams on the web.
If the calendar works in the browser but not in the desktop app, the installed Teams app may need restarting, repairing, resetting, or reinstalling.
Restart Teams fully
Close Teams completely.
On Windows, right click the Teams icon in the taskbar or system tray and choose Quit.
On macOS, quit Teams from the dock or menu bar.
Reopen Teams and check whether the calendar syncs.
If Teams has been open for several days, restart your computer as well.
Check whether meetings were created as Teams meetings
If a meeting appears in Outlook but does not behave like a Teams meeting, it may not include a Teams meeting link.
Open the Outlook calendar event.
Check whether it includes a Microsoft Teams meeting link.
If not, edit the meeting and add Teams meeting details if you are the organiser.
If someone else created the meeting, ask them to resend or update the invite.
Check calendar sync delay
Teams and Outlook can take a short time to sync meeting changes.
If a meeting was just created or changed, wait a few minutes.
Then refresh Teams and Outlook.
Sign out and back in if the meeting still does not appear after a reasonable delay.
Repair or reset Teams
If the calendar works in Outlook and Teams web but not the desktop app, reset the installed Teams app.
On Windows, open Settings.
Go to Apps.
Find Microsoft Teams.
Open Advanced options if available.
Select Repair first.
If that does not work, select Reset.
Reopen Teams and sign in again.
Check Microsoft 365 licence and mailbox access
For work or school accounts, the Teams calendar depends on Microsoft 365 services such as Exchange Online.
Ask your IT administrator to check:
- Your Microsoft 365 account is active
- Your Teams licence is assigned
- Your mailbox is active
- Exchange Online is available for your account
- Calendar access has not been restricted
- Teams app policies allow the Calendar app
Check organisation policies
Some organisations hide or restrict Teams apps through policy.
If the calendar is missing for several users, IT should check whether the Teams Calendar app is blocked, unpinned, or hidden by policy.
This is especially likely on managed work or school accounts.
Optional methods or tools
- Use https://outlook.office.com to confirm whether the calendar works outside Teams
- Use https://teams.microsoft.com to compare Teams web with the desktop app
- Pin the Calendar app in Teams if it is hidden under More apps
- Ask IT to check Exchange Online and Teams app policies
- Reinstall Teams from https://www.microsoft.com/microsoft-teams/download-app if the desktop app remains faulty
Best practices or tips
- Use the same account in Outlook and Teams
- Create Teams meetings directly from Outlook or Teams calendar
- Keep Teams and Outlook updated
- Restart Teams if calendar changes do not appear
- Report missing calendar issues to IT if Outlook web also has problems
Microsoft Teams calendar problems are usually connected to Outlook, Exchange Online, or account settings. If your calendar is missing from Teams, checking Outlook on the web at https://outlook.office.com helps confirm whether the issue is with Teams or the underlying mailbox.
If the calendar appears correctly in Outlook and https://teams.microsoft.com but not in the desktop app, the problem is likely local to the Teams installation. Restarting, repairing, or resetting Teams should usually restore calendar visibility and sync.
