Can I escalate an Azure support issue directly to Microsoft if my CSP partner can't resolve it?

Generally, as a CSP customer, support escalation paths typically go through your partner rather than you opening a direct Microsoft ticket yourself, since your partner holds the support relationship with Microsoft on your behalf. If your partner genuinely can't resolve an issue, a good partner will escalate it to Microsoft directly rather than leaving you stuck — this is one of the things worth evaluating when choosing a partner.
