    It seems you are encountering a server error (500) when trying to access the calendar. This type of error typically indicates an issue on the server side rather than a problem with your application or device. Here are a few steps you can take to troubleshoot this issue:

    1. Refresh the Application: As suggested, try refreshing the application to see if that resolves the issue.
    2. Check Service Status: Sometimes, server errors can be due to ongoing maintenance or outages. Check the Microsoft service status page to see if there are any reported issues with the calendar service.
    3. Clear Cache and Cookies: Clear your browser's cache and cookies, then try accessing the calendar again.
    4. Try a Different Browser: If the issue persists, try accessing the calendar using a different web browser or device to rule out any browser-specific issues.
    5. Contact Support: If none of the above steps work, consider reaching out to Microsoft support for further assistance, as they may have more insight into the server error you are encountering.

    Hi @George Lubas

    Welcome to Q&A Community! 

    Please understand that our forum is a public platform, and we will modify your question to cover your organization domain name in the description. Please notice to hide these personal or organization        

    You're encountering a known error code 500 in Microsoft Teams, specifically when trying to access your Calendar. This error, despite your M365 Business Premium license, strongly indicates a problem with your Exchange Online mailbox status, not necessarily your Teams license itself. 

    May I double confirm that you checked with Admin if your account still has License?  

    To check this kindly sign into admin.microsoft.com with Admin credentials > choose Active User under Users > click on your username > choose Licenses and apps > Expand Apps > Make sure that Exchange Online(Plan1 or 2) is selected.  

    If your account has License, kindly uncheck it and reapply it then wait the sync period to see if it will make any difference.

    Moreover, please try clearing Teams cache and let me know if there are any changes: Clear Teams cache - Microsoft Teams | Microsoft Learn 

      If the issue persists, I'd recommend you submit a support ticket. Kindly ask your admin to go to Office 365 Admin Center > Support > New Service Request.  

    The support engineers there have the correct escalation channel, and this is the most efficient way to report such issue. You can refer to this article to check the way how to raise a ticket: Ways to contact support for business products - Admin help.  

    I look forward to your response. Kindly note that the above requested information is required for further analysis and troubleshooting of your situation. Your patience and cooperation are much appreciated.
