Microsoft Store developer account creation fails at Account verification: "PartnerIntegrationService call failed: timeout of 30000ms exceeded"

I'm trying to register a new Microsoft Store developer account (company account) at storedeveloper.microsoft.com/onboarding.

The first three steps complete successfully (Account type, Business details, Contact details), but the last step, Account verification, always ends with:

Account creation failed

PartnerIntegrationService call failed: timeout of 30000ms exceeded

Reference: 68c5a50e90b71716f0b440dfe3972e0d

Pressing Retry gives the same error. This first happened on October 20, 2026, around 8:20 PM (US time).

What I've tried:

• Retrying several times
• Two browsers (Chrome and Safari) on macOS
• Signing in with a personal Microsoft account (MSA)

I also tried to open a support case through the "Create support case (MSA)" link, but the Engage Center page loaded indefinitely in Chrome, and in Safari it showed "No Access" with only a "Support for Business" workspace available.

Could someone from the Partner Center / Store team look up the reference ID above and let me know how to finish creating the account, or how to reach the right support team? Thank you!
