Hi ZENEI NAKATA,

Welcome to Microsoft Q&A forum. 

Based on your description and the screenshot (“Unable to cancel… Close and try again”), this behavior often happens when Teams Calendar can’t load/process the event details, so cancelling/deleting the item in Teams may fail. In that case, the most reliable approach is to manage the event directly from Outlook on the web (Outlook.com / Outlook on the web) using the same account you use to sign in to Teams.

To narrow this down quickly, could you please confirm these two points:

• When you sign in to Outlook on the web (Outlook.com) with the same Microsoft account you use for Teams (Gmail/Microsoft account), do you see that appointment/meeting in Calendar?
• Is this a one-time appointment/meeting, or a recurring series? (For recurring items, there are options to cancel an occurrence or the entire series.)

Once the two details above are confirmed, the most appropriate next steps will be provided to help remove/cancel the stuck item

Hello @ZENEI NAKATA,

Thank you for reaching out and for describing the issue you’re experiencing in Microsoft Teams.

 

To better understand what’s causing the problem and narrow down the root cause, could you please help clarify a few details below?

1/ Please confirm what type of account you are using. Is this a work or school account provided by an organization, or a personal Microsoft account (outlook.com, hotmail.com, gmail.com)?

2/ Could you let me know how the meeting was originally created. Was it scheduled from Microsoft Outlook or directly from Microsoft Teams?

3/ When deleting the meeting, which application are you using? Have you tried deleting it from both Teams (desktop or web) and Outlook (desktop or web), and does the issue occur in all cases?

4/ When the deletion fails, do you see any specific error message or warning, or does the action simply not complete without showing an error? If there is an error message, please take a screenshot and share it with me.

 

This information will help determine whether the issue is related to calendar synchronization, the client being used, or the account type.

Thank you for your cooperation. I look forward to your reply so we can continue assisting you.

 

Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. 

 

Kind regards,

To join new meetings and avoid issues from old appointments, try these steps:

1. Check if the old meeting is still active
   • Open the Teams app and go to the Calendar tab.
   • Locate the old meeting.
   • If it is in the past, it should not block joining new meetings. Deleting it is optional and mainly for cleanup.
2. Join the new meeting correctly Use one of these supported methods:
   • From Teams calendar:
     1. In Teams, select the Calendar tab.
     2. Find the new meeting and select Join.
   • If the invitation link does not work:
     1. In Teams, select the Calendar tab.
     2. Select Join with an ID (or Expand meetings menu → Join with Meeting ID on mobile).
     3. Enter the Meeting ID and Meeting passcode from the invitation.
     4. Select Join a meeting, then Join / Join now.
3. If “I can’t join” problems continue Common causes and actions:
   • The organizer has placed participants in the lobby → wait to be admitted or contact the organizer.
   • The meeting requires sign-in with a work or school account → sign in with the correct Teams work/school account if prompted with messages like “Sign in to join this meeting” or “Sign in with a different account to join this meeting”.
   • The meeting has end-to-end encryption or other org policies → contact the organizer if you see messages like “Your organizational policy does not allow you to join this meeting”.
   • The meeting is not an online meeting → ask the organizer to ensure the event is created as a Teams meeting.
   • On a phone/tablet, do not use a mobile browser; install and use the Teams mobile app.
4. If meetings do not appear in the Teams calendar
   • Check the email account where the invite was sent (including junk folder).
   • If using Teams for work or school as well as personal, switch to the correct account so the right calendar is visible.

Old appointments normally do not prevent joining new meetings. Focus on joining via the correct account, using the Join button in the Teams calendar or the Meeting ID and passcode method, and check any join error messages for policy or sign-in requirements.
