Cannot access a shared calendar in teams accepted the invite

Hello @Tami Kaido,

Thank you for posting your question in the Microsoft Q&A Forum.  

To help us investigate further, could you please provide:

• A screenshot of the error message or pop-up you see when trying to access the shared calendar?
• Could you ask the person who shared the calendar to send the invite again, and let us know if the issue persists?
• Are you experiencing this issue on the Teams desktop app or the web version?
• Does this problem occur only for you, or do other users who received the same invite also encounter the same error?
• Can you access the shared calendar through Outlook Calendar without any issues?

If possible, could you try following this guide to share the calendar again and let us know if it works: Share an Outlook calendar as view-only with others - Microsoft Support

Please provide as much information as you can, the more details we have, the better we can investigate and guide you toward a solution.

Thank you for your patience, and I’m here to assist as much as possible within my role.
