Dear StevenVE,
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description regarding "Microsoft Teams Room version 5.2.115.0 bug: Teams Room account can't login". My sincerest apologies for the inconvenience this might be causing you, kindly try to perform factory reset to check if it will make any difference Use the Microsoft Teams Rooms recovery tool - Microsoft Teams | Microsoft Learn
If the issue persists, I therefore believe that this issue should be further investigated by our online technical support team. A support Engineer can further connect with you remotely, for further troubleshooting and involve the backend team where need be. The team might request for your public IP address or collect certain detailed logs information with more technical resources. Please understand that as public forum support, we don’t have higher permissions to check and analyze these logs or check the IP addresses and considering your scenario maybe inconveniencing, to quickly help assist, kindly contact your organization admin or you can create a service request to report this symptom to our online channel. Here is contact support document: Get support - Microsoft 365 admin | Microsoft Learn
Important Note: If any organization's Office 365 Business / Enterprise subscription is from syndicate or reseller partner and if global admin cannot open service request from their side, they may need to contact reseller support provider so that they can help to global admin for opening service request from their side, after that Office 365 technical support team can involve in service request. Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
