3] Check the server status of Teams as well as Sharepoint and OneDrive
You might be unable to send files over Teams because of an ongoing server issue going on at the end of Microsoft Teams. Hence, do check the current server status of Teams and make sure the services are up and running.
To do that, you can use the Office Service Status page and check if Teams services are down or not. If the servers are facing downtime or they are under maintenance, wait for some time and then try uploading the files.
Apart from that, you also need to check if Sharepoint and OneDrive services are unreachable or down currently. For file sharing in businesses, Microsoft uses SharePoint and OneDrive services. You won’t be able to share files on Teams if any of these services are unavailable at the moment. Hence, do check if Sharepoint and OneDrive services are down using an online website monitors tool like DownForEveryoneOrJustMe.com, IsItDownRightNow.com, DownOrIsItJustMe.com, etc.
If Teams and Sharepoint and OneDrive services are running fine, move on to the next fix to resolve the issue.

7] Check SharePoint permission
You might be denied permission to upload files by your organization. Hence, you can try contacting your admin and check with him/her if you are allowed the file-sharing permissions or not. If not, request the admin to grant you the required permissions.
