An Azure relational database service.
Hello @Ryan M,
Thank you for posting your query on Microsoft Q&A.
Typically, "Microsoft Services" appears when you're using a personal account (such as Gmail, Hotmail, or MSN) to authenticate to Azure resources, where your users may have been added as guest accounts in the tenant.
Could you please confirm whether you're using a personal account or a work/school account to authenticate with Azure SQL Server?
If you're using a personal account, try directing the authentication to your tenant by modifying the token URL in your Python script to: https://login.microsoftonline.com/<Replace your tenant_ID>.
Please check these steps, and let me know if the issue persists.
Additionally, if the affected users try to log into the Azure Portal or Office portal, do they encounter the same error message?
Thanks,
Raja Pothuraju.
